SUMMARY
Results of aquatic monitoring at Byron Generating Station during the fourth year of the current study are presented in this report. The five-year construction and preoperational monitoring program includes sampling at stations on I the Rock River between Byron aad Oregon, Illinois, at the mouths of tributaries and in Woodland Creek, which drains the site. Also included are statistical comparisons of the data of the current year with that of previous years of the study. Composition of major algal groups and dominant species was similar in both phytoplankton and periphyton studies. Diatoms continued to predominate in the algal flora, particularly in the periphyton. Peak phytoplankton abundance occurred in spring, continuing a trend seen in previous years, while periphyton I reache d maximum density in fall, a result similar to Years 1 and 2. High river flows l from late spring through early fall were the apparent cause of shifts in seasonal periphyton abundance, as well as an unusual cyanophyte pulse in summer periphyton, II which replaced the usual chlorophyte pulse at that time. Although river and creek stations care consistently different in periphyton species cornposition and abun-l dance, such differences were not apparent between river stations for either periphyton or phytoplankton. Higher spig primary productivity at R5 was repeated in the current year and is probably an impoundment effect of the Oregon Dam, l which results in greater water clarity at that station. In general, algal diversity was l reduced in Year 4, possibly a result of high flow stress. Algal community structure and population densities continue to indicate that the Rock River is moderately eutrophic. The zooplankton community of the Rock River in the study area I continued to display a fauna typical of large rivers and impoundments, and, as in all previous years of the study, was strongly dominated by rotifers in all but the winter quarter. Community structure was similar at upstream and downstream stations, although the upstream community exhibited greater density except in winter. ~ l 11 1
e I ESPEY, HUSTON & ASSOCIATES, INC. Overal! densities were low in Year s, probably due to high flow rates, turbidity and lower water temperatures in spring and summer. Comparable seasons in different years were usually different in terms of density and diversity, due probably to differences in physical parameters. Macroinvertebrate densities in both the natural and artificial substrate programs in Year 4 were intermediate between the low densities of Year 1 and the g higher denrities of Years 2 and 3. Unusually high summer flows were the major E factor contriouting to low overall densities. The dominant taxa in Year 4 were similar to previous years in both programs, with the exception of unusually high abundances of Simulium jenningsi which coincided with peak flow periods of May and July. Station WZ (Woodland Creek) was differentiated from other stations by a different assemblage and low densities, attributable to habitat differences. Sta-tion S5 tended to have higher densities and S3 lower densities than river stations. Of river stations, R1 was most distinct in composition and lower abundance of benthos and was most similar in that regard to R2. 2R was most often separable in the artificial substrates program on the basis of abundance. Of the 50 species of fish collected in the . study to date, 39 we*e collected in Year 4. One of these was new to the study, the brook stickleback. As before, rough fish dominated the catch by biomass and number of individuals caught. The black crappie was the most abundant gamefish caught, followed by channel catfish. Fish condition factors, year class data, and parasitism appeared within the ! normal range, although parasitism was the highest yet noticed in the current study. The Year 4 catch, by all gear types, was second only to Year 3, primarily due to a low catch in fall. The creel census indicated that fishermen had the highest catches l per rod-hour and per man-hour during the four years studied. Channel catfish and carp were the fish most commonly caught. i E i Upstream and downstream fish sampling stations were not differentiated E in statistical tests, but the discharge area appeared to have greater fish abundance, l iii
I e ESPEY, HUSTON & ASSOCIATES, INC. especially during periods of high water. Creek stations yielded larger gamefish catches than river stations. I Levels of most physico-chemical parameters indicated continued slight improvement in water quality of the Rock River in the vicinity of Byron Generating Station. Phosphate concentrations, as in previous years, exceeded the Illinois General Standards at most stations in all quarters. Iron exceeded the General Standards at only one or two stations in spring, summer and fall, but was above Public and Food Processing Water Supply Standards at most stations in spring and summer and at creek mouths in fall. Ammonia was within standard limits at all times for the second consecutive year. I Most biological parameters analyzed appeared to follow normal seasonal trends, except as affected by the unusual temperatures and hydrologic regimes during the fourth year of study. The only effect of power plant construction noted was the higher abundance of fish in the vicinity of the newly constructed discharge I, canal, especially at times of high water levels. I I I .

1.0 INTRODUCTION
I Results of the 1978-1979 (Year 4) aquatic monitoring survey at Byron Generating Station are presented in Sections 2.0 - 7.0 and in Appendix A. Samples were collected at designated sampling locations on the Rock River between Byron and Oregon, Illinois, at the mouths of tributaries and in Woodland Creek. The I specifi sampling locations are shown in Fig.1.1. The detailed descriptions of materials and methods are presented in Appendix B. The same statistical methods were applied, where appropriate, to all programs. Comparisons between stations (and years) were made using data that had been nortualized by the use of the In(x+1) transform. The only exceptions to this were water chemistry and cell volume data. Differences between station means within the current study year were first tested using the one-way analysis of variance (Snedecor and Cochran 1967). When significant results were obtained from the one-way ANOVA, the station means were tested by the Scheffe multiple t g comparison to detect significant differences between station means. Interstation 5 differences in the frequencies of dominant spe'cies were tested by the use of a chi-square test for the similarity of multinomial probabilities. The data for the first four years were used to compare stations and equivalent seasons of the four years by a two-way ANOVA and Scheff% test. In an statistical tests an a priori level of significance of 5% was used. 1 I The term " dominant", as used in this report for statistical purposes, for inclusion of species in ranking tables, and for discussions, refers to any species or taxonomic unit that constitutes 5% or more of the total standing crop at the lI locations under consideration.

I e ESPEY, HUSTON & ASSOCIATES, INC. I 2.0 PHYTOPLANKTON I The 1978-1979 quarterly phytoplankton samples were collected on 23 May (spring),1 August (summer),8 November (fall) 1978 and 20 February (winter) 1979. Materials and methods are described in Appendix B. 2.1 RESULTS 2.1.1 Data Analvses Absolute and relative abundance (number /ml) of phytoplankton, by quarter, is presented for Stations R2 and R5, respectively, in Figs. 2.1 and 2.2. Absolute zad relative abundance based on biovolume (pl/1) is presented for these stations in Figs. 2.3 and 2.4. Average, maximum, and minimum densities (number /ml), along with associated variances 4.ad relative abundances, are listed for I, total phytoplankton, algal divisions and dominant species on a quarterly basis in Table 2.1. These analyses are reiterated on a biovolume basis (pl/1) in Table 2.2. Table 2.3 lists, by replicate, diversities and redundancies calculated for each phytoplankton sample during the current study year. Results of the quarterly in-situ primary production measurements are listed in Table 2.4, and chlorophyll a, concen-trations are given in Table 2.5. Results of the one-way analysis of variance (ANOVA) and, when appropriate, Scheff( multiple cornparison test, are presented by quarter, in Table 2.6 along with the data of Table 2.1 expressed as a In(x+1) transform. Average and range of cell volumes (p ) are given for dominant phytoplankton species in Table 2.7. Also included in Table 2.7 are the results of the one-way analysis of variance and Scheffd multiple comparison test on cell sizes I between stations. The results of the one-way analysis of variance and Scheffi multiple comparison tests on chlorophyll a densities, between stations, are presented in Table 2.8. Table 2.9 lists the results of the chi-square test of similarity comparing the distributions of densities among dominant species between stations. Dominant species are ranked in Table 2.10 on the basis of annual average numerical I m
e l ESPEY, HUSTON & ASSOCIATES, INC. density (number /ml), with rankings based on annual average biovolume density (pl/1) listed in Table 2.11. The two-way ANOVAs comparing this year's phytoplankton standing crops to those observed during corresponding seasons in the 1975-1976, 1976-1977, and 1977-1978 study years are presented in Table 2.12. Table 2.13 lists the water temperatures and current velocities at one meter and the Secchi disk readings obtained during the four years of study. A complete listing of the phytoplankton species encountered in each sample replicate and corresponding densities (number /ml) is presented in Appendix Table A.1. The same species are listel in Appendix Table A.2 with biovolume densities (pl/1). I 2.1.2 Seasonal Patterns 2.1.2.1 Standing Crops I Total phytoplankton standing crop (no./ml) was greatest at both stations during the spring quarter (Figs. 2.1, 2.2; Table 7.1). Both stations had approximately I the same standing crop in the spring quartet with 82,619 cells /ml at R2 and ! 84,923 cells /ml at RS. A dramatic decrease was observed in standing crop for the surnmer quarter, with 13,295 and 1,297 cells /ml at R2 and RS, respectively. An I increase to approximately 34,000 cells /ml at R2 and 28,000 cells /ml at R5 occurred during the fall quarter, followed by a decline to approximately 390 cells /ml at both stations during the winter quarter. While no significant difference in total phytoplankton between stations I was observed in spring and winter quarters, statistically significant differences were found for the summer and fall quarters (Table 2.6). Seasonal patterns in total standing crop expressed as biovolume (pl/1) followed the pattern cf absolute abundance expressed as individual cell counts. The greatest biovolume occurred in the spring with a sharp decline in the summer, followed by an increase in the fall and a decrease in the winter (Figs. 2.3, 2.4; Table 2.2). I ! 2-2 E
I e ESPEY, HUSTON & ASSOCIATES, INC. The diatoms (Bac.illariophyta) were the dominant group at both stations during the spring, fall, and winter quarters (Figs. 2.1, 2.2; Tables 2.1, 2.3, 2.4). However, during the summer quarter, the diatoms accounted for only 38 and 36% of the phytoplankton populations of Stations R2 and R5, respectively (Figs. 2.1, 2.2; Table 2.2). This was less than half their celative abundance during the spring quarter (86 and 85% for R2 and RS, respectively). Blue-green algae formed 54 and 51% of the phytoplankton population at Stations R2 and RS, respectively, in the
.,ummer quarter. Likewise, the blue-green algae dominated in terms of biovolume during the summer quarter at both R2 and RS, forming 68 and 65% of the population, respectively.
The summer dominance of blue-greens and low total densities is an occurrence unique to the four years of sampling conducted at this site, and may well be a result of the unusual summer high flow conditions of 1978. Although planktonic species of Oscillatoria exist, a more likely source for this organism is the flushing of backwater areas and farm ponds. I. The Euglenophyta never formed more than 1% of the population density at either station throughout the year, and only reached maximum biovolumes of 8 and 5% (RZ and R5, respectively) during the fall quarter (Tables 2.1, 2.2, 2.3, and 2.4). l The Chlorophyta contributed a maximun2 rek.tve abundance of 11% in l the spring (both stations). During the summer, the Chlorophyta dropped to 6% at R2 lule rematcing steady at RS. The fall quarter saw chlorophyte densities at both I stations reduced to 6% with another reduction to 3% (both stations) during the winter quarter. This pattern was not mirrored by the biovolume of Chlorophyta which remained at 1% throughout the year except for an increase to 6% at Station R5 during the summer quarter (Table 2 2). The Cryptophyta (uncertain status) densities were the same at both stations for the year, comprising 2% of the population during the spring and summer I . 2-3
e I ESPEY, HUSTON & ASSOCIATES, INC. quarters and less than 1% during the fall and winter quarters. The biovolumes for tais group generally followed the density pattern except for the increase in biovolume (5%) at R5 over the value at R2 (2%) during the spring quarter (Table 2.2). The greatest difference between the two stations (R2 and R5) occurred during the summer quarter when the densities of six of the seven algal divisions were found to be significantly different (Tabic,2.6). Otherwise, each quarter had only one algal division in which the mean density between stations was significantly different (Table 2.6). During the spring and fall quarters, the centric diatom Stephanodiscus minutus was the most abundant species at both stations. This was true in terms of both numerical density and biovolume (Tables 2.1 and 2.2). In the summer quarter, however, this species was not present as dominant and the filamentous blue-green alga Oscillatoria sp. dominated both stations in terms of both number and volume (Tables 2.1 and 2.2). The centric diatoms Cyclotella meneghiniana and Melosira granulata made up a combined average of 26% of total numbers at both stations during the summer quarter compared to 49% for Oscillatoria sp. (Table 2.1). hhanodiscus minutus again appeared as a numerical dominant in the winter quarte.r at botn stations (15%). During this period the pennate diatoms Gomphonema olivaceum, Nitzschia dissipata, N. linearis, Diatoma vulgare, and l Synedra ulna occurred as dominants along with Chroccoccus sp. (Cyanophyta). This l was the only sample period other than summer in which the centric diatoms did not completely dominate the phytoplankton. In terms of biovolume (Table 2.2) Stephanodiscus minutus was not represented at all among dominant algae. The most notable change between the fall and winter quarters was the decrease of the centric diatom Stephanodiscus minutus and the increase, in both number and biovolume, of the pennate diatoms Gomphonema olivaceum, Nitzschia dissipata, N. linearis, Diatoma vulgare, and Synedra ulna (Tables 2.1 and 2.2). E l E l 2-4 ! E
I e ESPEY, HUSTON & ASSOCIATES, INC. I The one-way analysis of variance between stations for dominant algal species in terms of density was the reverse of that observed for biovolume (Tables 2.6 and 2.7). While no statistical differences existed between the numerical density of dominants for the spring, fall, and winter quarters, all three dominants were significantly different between R2 and R5 for the summer quarter (Table 2.6). By contrast, there was no significant difference in cell volumes between R2 and R5 for the summer quarter. However, significant cell volume differences between the stations existed for Cvelotella meneghiniana during the spring and fall quarter and for Synedra ulna during the winter quarter (Table 2.7). . I ';. l.2.2 Diversity I ' Fhytoplankton species diversity was highest during the winter quarter with values of 2.6 and 2.8 for Stations R2 and RS, respectively (Table 2.3). By contrast, species diversity was lowest during the spring quarter with a value of 1.7 for both stations. Summer and fall ranked second and third, respectively behind the
'I winter high for species diversity. The mean redundancies were similar for both the spring and summer populations and slightly lower for the fall quarter. The lowest redundancies (winter) corresponded to the highest diversities at R2 and R5 (Table 2.3).
2.1.2.3 Chlorophyll a I Mean chlorophyll a concentrations varied from a winter low of <1 p g/l to a fall high at R2 of 26 pg/l (Table 2.5). The spring quarter had the largest variation of chlorophyll a_ values between the stations for the year. However, this variation was still statistically insignificant (Table 2.8). The fall chlorophyll a_ values of 26 and 24 ug/l for R2 and RS, respectively, were similar to the R5 spring value of 25 pg/1. The mean summer values of 3 p g/l for both stations were actually closer to the winter values of <1 pg/l than any other value. The low summer values are reflective of both the low numbers present and the difficulty of chlorophyll I extraction from blue-green algae, relative to diatoms. I .E 2-5

e I ESPEY, HUSTON & ASSOCIATES, INC. I 2.1.2.4 Primary Productivity Phytoplankton primary productivity values for the fourth year are given in Table 2.4. Generally speaking, the low values occur during the spring and winter 3 quarters (89 to 144 u gC/m /hr). During summer, primary production ranged from u average of 102 pgC/m /hr at R2 to 627 pgC/m /hr at RS. The summer value for Station RS (627 pgC/m3 /hr) is extremely high for the amount of chlorophyll a recorded from this station, and is opposite to the summer numerical and biovolume relationship discussed above. The high fall values recorded for both stations are consistent with observations in previous years of fall blooms in this reach of the Rock River. 2.1.2.5 Dominant Species Comparisons The chi-square analysis for similarity of dominants detected significant differences between stations in all quarters except spring (Table 2.9). 2.1.3 Comparisons with Previous Years I The results of the two-way analysis of variance and Scheffe' comparisons pcrformed on the four years of data are presented in Table 2.12. As previously mentioned in prior reports, statistically significant differences between stations and years were observed within all four years. There seems to be an increasing number of significant differences between stations in terms of algal divisions over the four year period. This increase is most notable in the spring and summer quarters be, seen the 1976 and 1977 annual surveys. Likewise, the number of significant variations between years and algal divisions has increased over the survey period to the point that during the 1978-1979 survey, only two algal divisions in the spring and two in the fall (the same two) were not shown to be significantly different from the previous year. I I 2-6
I e ESPEY, HUSTON & ASSOCIATES, INC. The numerical abundances during the various quarters throughout the four year survey have been erratic at best. No patterns are distinguishable beyond those of a very general nature. As examples of this behavior, a tenfold increase was observed between the summer quarters of 1976 and 1977 for both stations. Then in the 1978 summer quarterly survey, algal densities experienced a fourfold decrease at R2 and a 48-fold decrease at R5. I Although diatoms have always been observed to be the a .ainant algal form over the years of the study, there was an increase in the occurrence of green algae (Chlorophyta) and blue-green algae (Cyanophyta). Chlorophyta have generally been a dominant algal form during the spring and summer quarters, although this has only become pronounced during the last two years (Years 3 and 4). Blue-green algae are much less a dorninant algal form than the green algae, and the blue-greens are almost always confined to the summer quarter. The first survey year (1975-1976) was very different from the remaining years due to the total absence of both green and blue-green algae from the dominant forms. There has been a great amount of variation in the phytoplankton species I diversity over the four year period. Af ter experiencing an increase during the second annual survey period and a slight decline during the third annual survey, the spring quarter phytoplankton species diversity during the fourth annual survey was back to its 1975 level. By contrast, the phytoplankton diversity of the winter quarter increased from approximately 2 to 3 between the first and second annual surveys, and has consistently stayed at that level. The fall quarter 1977 survey demonstrated a decrease from the same quarter of the first and second annual surveys. However, the fall quarterly survey for 1978 showed the diversity to be identical to the same quarter of the first annual survey (1975). Diversity during the summer quarter over the four year survey has been relatively stable. Like the numerical abundance, chlorophyll a, values are somewhat erratic over the four year survey. The winter quarter values are generally low and with the exception of the 1977 fall quarter, fall values are generally the highest of any lI
- 2-7
e l ESPEY, HUSTON & ASSOCIATES, INC. annual survey. Spring quarter chlorophyll values were only similar during the years 1976 and 1978. During the spring quarter of 1977, the values were twice tne aforementioned values, whereas the spring 1975 values were the lowest observed for any spring quarter (11 pg/1). Summer quarter values for 1976 were the highest observed during the four year study with a decrease to less than one-half that in 1977. Summer quarter values for 1978 and 1975 were equally low. Primary production is an extremely variable parameter, being dependent upon a number of biological, chemical, and physical factors. There is a general increase in carbon fixation during the four year study, although there is a great deal of variation between years and between stations during certain quarters of the same year. 2.2 DISCUSSION Numerical abundances at Stations R2 and R5 have been roughly similar throughout the four year study. The one exception to this is the summer quarter for this year (1978), where a tenfold decrease occurs between R2 and RS. Other than that, seasonal trends in relative abundances of the major groups were quite similar at both stations during all four years of the study. Table 2.13 lists water temperature and current velocities at one meter I depth as well as the Secchi disk readings obtained during the four year study. These data show that Station R5 generally had a lower current velocity and during the spring had a consistently greater transparency than did Station R2. The dam just below Station R5 at Oregon, Ill., is the major determinant of the aforementioned conditions. The lack of consistent differences between the algal flora of Stations R2 and RS, however, indicates that the biological effects of this impoundment, at least on the phytoplankton, are relatively small. Increased abundances of non-diato m algae, including Chlorophyta, Cyanophyta, Euglenophyta, and Cryptophyta, were apparent during the second, third 2-8 I E
I e ESPEY, HUSTON & ASSOCIATES, INC. and fourth years of the study when compared to Year 1 (Table 2.12). Although the most abundant species, centric diatoms, were fairly similar during the four years of I the study, increases in pennate diatoms and in non-diatom species were noted among the dominants in the second, third, and fourth years of the study. Among the centric diatoms, the decline of Cyclotella meneghiniana as a dominant during the fall and winter c,f the fourth year brought to an end its presence as a dominant for the entire year, as had been the case for Years 2 and 3. By far, the major portion of algae making up the phytoplankton popula-tions v as diatoms (Bacillariophyta) (Table 2.11). In terms of biovolume and density, the ccatric diatoms occurred in excess of the pennate forms. The increase in the number of dominant species with each succeeding study year is a complement of the observed changes in diversity with time. The very high standing crops, chlorophyll a_ concentrations, and primary production rates, together with the large number of species and genera tolerant of enriched conditions (Lowe,1974; Palmer 1969), indicate that the Rock River continues to carry a heavy nutrient lo.ai and that observed diversity changes are not reflective of a decrease in nutrient levels. ' Ibis conclusion is supported by the continued high levels of phosphorous, nitrogen and silica reported in Table 7.4. l l The temporal changes apparent in this data are probably best explained as resulting from the flood events of spring 197:s and summer 1978. D' lerences between the first year and subsequent years represent a recovery in abundance of major groups and species better adapted to standing waters or low current velocities l
- and warmer water temperatures than were present during 1975.
t Although the impoundment at Station R5 may be exerting some effect on the phytoplankton, those effects have not been pronounced to date. No effects attributable to construction were evident in the phytoplankton. I I 2-9

2.3 CONCLUSION
S
- 1) Little consistent differenc<. an be demonstrated in phytoplankton parameters between Stations 12 and RS. The consistently higher rates of spring primary production at Station R5 suggest that the greater clarity of wate resulting from the impoundtnent at Oregon, Blinois may be responsible for these differences.
- 2) Peak phytoplankton abundance occurred during spring at both I
stations. Timing of peak phytoplankton abundances has varied in each study year, but the observed seasonal shif ts in abundance peaks are as likely to be char.ce occurrences as to be real changes in se asonal succession.
- 3) Major group composition and dominant species were very similar between years, as was the seasonal succession of dominant species.
However, Years 2, 3, 2nd 4 were more similar to one another than i to Year 1, especially with regard to relative abundances of major groups and to the dominant species observed. These differences I are most likely to have been caused by the differences in hydro-logical regime G.e., the spring 1975 and summer 1978 floods).
- 4) Phytoplankton community structure and production parameters continue to indicate that the Rock River is at least moderately eutrophic.
- 5) The diversity was lower in Year 4 than in Year 3 during spring and summer and higher in fall.
- 6) No effects on the phytoplankten due to construction were evident.

I e ESPEY, HUSTON & ASSOCIATES, INC. 3.0 PERIPHYTON Periphyton samples were collected, in this study, in two separate programs: the " Quarterly" series, and the " Bimonthly" series. I For the quarterly periphyton program, slides wi .e incubated for approxi-mately one month in diatometers located at Stations R1, R2, R3, R4, RS, S3, S4, S5, W1, and W2. These slide sets were recovered for analysis on 20 May, 8 August, 3 November 1978, and on 19 February 1979. For the bimonthly periphyton prt, gram, slide sets were recovered from diatometers at Stations 2R (right, or west bank), 2L (lef t, or east bank), 3R, 3L, 4R, and 4L after approximately one month's residence in the river. Slide sets were collected from these stations on 20 March,19 May,13 July,13 September, and 3 November 1978 and 31 January 1979 In both programs, missing samples and the reason for this absence are noted on the summary data tables. 3.1 RESULTS I 3.1.1 Data Summary I Absolute and relative abundances of algal divisions, by number density 2 (number /10 cm ), are graphed for each station in the quarterly periphyton program in Figs. 3.1-3.9 Absolute and relative abundances based on biovolume density (pl/10 cm ) for the quarterly periphyton stations are graphed in Figs. 3.10-3.18. I Graphs, by station, of absolute and relative abundance of algal divisions, as 2 number /10 cm , for the bimonthly periphyton are presented in Figs. 3.19-3.24, while the same information, based on biovolume density, is presented in Figs. 3.25-3.30. Average and range of densities (number /10 cm2), along with the associated I I

l e I ESPEY, HUSTON & ASSOCIATES, INC. variances and proportions of total standing crops, are presented in Table 3.1 for algal divisions and dominant species in the quarterly program. This data is repeated in Table 3.2, except that density is based on biovolume (pl/10 cm 2). Average and range of biomass (ash-free dry weight, mg/10 cm ) are presented for quarterly periphyton samples in Table 3.3. Table 3.4 lists diversity and redundancy estimates, by replicate, for all quarterly periphyton samples. Tables 3.5, 3.6, 3.7, and 3.8 present cell number density, biovolume density, biomass, and species diversity, respectively, for the bimonthly periphyton program. These tables follow the same formats as Tables 3.1-3-4. The results of the one-way analyses of variances (ANOVA) and Scheffi multiple comparison tests are listed for the quarterly periphyton program in Table 3.9 along with the In(x+1) transform of the data in Table 3.1. Table 3.10 presents average and range of cell volumes for dominant species in the quarterly program and one-way ANOVA and Scheffi Test results and that data. Table 3.11 contains the one-way ANOVA and Scheffi Test results and the In(x+1) transform data from Table 3.5 for the bimonthly g periphyton program. Average and range of cell volumes, one-way ANOVA results, 5 and Scheff( Test results for the bimonthly periplyton are shown in Table 3.12. Table 3.13 presents the results of the chi-square test of similarity for the distribu-tion of dominant species between stations of the quarterly periphyton program, while this data is presented for the bimonthly program in Table 3.14. The annual ranking based on cell number of all dominant species encountered in the quarterly program is presented in Table 3.15, while dominant species ranking based on biovolume is presented in Table 3.16 Table 3.17 presents the annual ranking of dominant species encountered in the bimonthly program based on cel. number, and the ranking based on biovolume is shown in Table 3.18. Tables 3.19 as ?.20 present the two-way ANOVA results and Scheff( Test results for the quarterly and bimonthly programs, respectively. Complete listings by station, date, and replicate of all species found in 2 the quarterly program and their number densities (number /10 cm ) are presented in Appendix Table A.3. This information is repeated in Appendix Table A.4, except E 3-2 I
I e ESPEY, HUSTON & ASSOCIATES, INC. that biovolume densities (pl/10 cm ) are given. Appendix Table A.5 presents complete aecies listings and number densities for the bimonthly program, while biovolume densities for these species may be found in Appendix Table A 6. The results of the two periphyton programs are discussed separately in the following subsections to avoid confusion. The discussion of the Rock River ) periphyton community in Section 3.2 covers both programs together, since they differ only in sampling schedule. 3.1.2 Quarterly Periphyton l 3.1.2.1 Current Study Year Z
. Periphyton densities (cells /10 cm ) were generally highest during the fall quarter and lowest during the winter quarter. Due to the large number of samples lost during the spring quarter, comparisons between the spring and summer quarters
.I. are difficult to make. Total periphyton densities of the river stations ranged from 6 3 2.74 x 10 cells /10 cm at R5 in the fall to 8.1 x 10 cells /10 cm at R4 in the winter. The creek stations, likewise, demonstrated low densities during the winter quarter with S3 having a density of only 113 cells /10 cm2 . This same station had a total periphyton density of 56,973 in the fall. The maximum density recorded at a 5 creek station was 1.59 x 10 at S5 during be spring. Biovolumes (pl/10 cm ) generally reflected the same trends observed with density, although the green algae (Chlorophyta) at R3 during the winter quarter constituted a greater portion of the total density than they did in terms of biovolume. Like density, biovolumes were greatest in the fall and smallest in the I winter quartar. 2 The range of biovolumes in the river stations extended from 2 3.0 pl/10 cm at R3 in the fall to .02 pl/10 cm at R4 in the winter. The river station with the maximum density (cells /10 cm ) had a biovolume of 2 9 pl/10 cm . There were so few biovolume calculations for the creek stations (due to inadequate counts) that generalizations regarding these stations are impossible. I 3-3
.I
e I ESPEY, HUSTON & ASSOCIATES. INC. One-way analysis of variance and subsequent Scheffe' multi-group com- : parisons are summarized in Table 3.9. In the spring quarter, W2 was significantly lower in density than SS, R2, or R3, all of which were statistically siri,ilar. The : extremely low values at S3 in the summer caused it to differ significantly from all other stations. During the fall quarter, the river stations w-re not significantly different from ocu another. The same was true for the creek stations. Here was, however, a statistical difference between the river stations and tne creek stations. His difference between river and creek was obliterated in the winter quarter. He W extremely low values at S3 dt"ng the winter quarter caused this station to be significantly different from all others during this quarter. The Chlorophyta only formed a significant portion of the total peri-phyton during the winter quarter at R3, when it constituted 38% of the population. At all other times, the Chlorophyta accounted for 2% or less of the total periphyton standing crop. Most of the dominant species encountered d. iring this survey were pennate diatoms. Some incree.ses in the centric diatoms were observed throughout the year, especially in the creek stations. Melosira varians accounted for 26% of l total numbers at S4 in the summer quarter. At this same station in the fall, an unidentified centric formed 51% of the standing crop while at S3 the same diatom E W had a relative abundance of 57%. Winter saw the return to dominance by the pennate diatoms. However, the dominance by this group was not, then, centered around the dominants Navicula tripunctata schizonemoides, Nitzschia linearis, j and/or Gomphonema parvulum as was the case during the spring and summer l quarters. Rather, a larger group of pennate forms came to occupy smaller individual portions of the dominant group (Table 3.1, winter quarter). The annual ranking of dominnt species based on numerical and bio-volume densities is presented in Tables 3.15 and 3.16, respectively. It both cases l there was a preponderance of pennate diatom species, with Gomphonema parvulum heading both lists. I I E 3-4 1 I
E e ESPEY, HUSTON & ASSOCIATES, INC. Cell volumes of dominant species and statistical comparisons thereof between stations in each quarter are presented in Table 3.10. Statistically signifi-cant differences in cell volumes were observed for at least one species in all quarters, except the fall. During the spring, volumes of Navicula tripunctata were significantly greater at R3 than at either SS or W2. During summer, volumes for I Gomphonema_ parvulum were significantly higher at R2 than at R3, R4 and S4. He cell volume for Cymatopleu g solea was significantly higher at R4 than at S4 during the winter. Periphyton biomass (ash-free dry weight, Table 3.3) values werd gen-erally higher during the summer quarter and lowest during the winter quarter. Spring and fall tended to have values intermediate between the summer and winter values. There was no station which consistently showed values lower than other stations. Mean diversity values seerned initially to be slightly lower in the river I than in the creeks during the spring (an average cf 1.4 for R2 and R3 compared to 2.3 for SS and W2)- ne increase in diversity of the river stations over the creek stations which begins in the summer, reached a climax in the fall quarter with a large difference in diversities between the river and creek stations. However, the winter quarter, like spring, reveals little if any difference in terms of species diversity. Redundancy values were uniformly low in all quarters ranging from 0.084 at Station S3 in fall to 0.582 at Station R2 in the spring. 3.1.2.2 Comparison with Previous Years ne spring 1978 levels of total periphyton at the river stations were less I than one half of those recordeu in 1975. The rPrer stations in 1978, for which data is available, were almost completely dominated by diatoms. Although diatoms dominated in 1975 as well, there also occurred small percentages (1-3%) of Chlorophyta and Cyanophyta. Likewise, the creek stations in 1975 also contained much higher levels of total periphyton than occurred in 1978. For example, W2 had I
, 35
e I ESPEY, HUSTON & ASSOCIATES, INC. a total of 23,186 in spring 1978 and over 64 million in the same area in spring 1975. Densities for both river and creek stations in the summer of 1978 were, again, less than one half those of 1975. In addition, more algal divisions were dominant in 1975 than in 1978. Station S4 in 1978 had only 142,000 individuals per 10 cr: as opposed , to over 1,300,000 in 1975. The differences in densities between the spring and summer quarters of g 1975 and 1978 are, at least in part, due to the fact that natural substrates (rocks, E submerged grasses, etc.) were sampled for periphyton during these quarters in 1975. Thereaf ter, diatometers were used for collection of periphyton. With the change to diatometers in the fall of 1975, total periphyton values rose to over 4 million individuals per 10 cm . This was twice the number observed at the river stations in 1978. However, the proportions of diatoms and other algal divisions were similar between the two years. Creek stations in 1978 had much lower densities with between 25 and 73 Thousand individuals per 10 cm as opposed to between 3 and 5 million in 1975. There was no winter sample in 1975 to compare with 1978 values. I The trends in biovolumes were much the same for all seasons in the river except that R1 had a much higher absolute abund. ace in the spring of 1978 than in the same quarter of 1975. This difference could be the result of differing substrates (artificial as opposed to natural). Station R5 showed the same pattern as R1 in the spring quarters of 1975 and 1978. The creek Stations S3 and S5 had large biovolumes in the spring and fall of 1975, but lacked sufficient numbers for this calculation in 1978. In addition, there was a large amount of Chlorophyta present in the spring of 1975 at the creek stations and almost none at the same stations in the same quarter of 1978. Corresponding to the density, ash-free dry weights were much higher in 2 1975. A 1975 spring quarter range of 9.38 to 15.00 mg/10 cm was found for the river stations and a range of 3.5 to 43.75 was found for the creek stations of the 3-6 I I
I e E3PEY, HUSTON 4. ASSOCIATES, INC. same quarter. The range for all stations during the spring quarter of 1978 was 0.75 to 3.63. His same general trend applied to the summer and fall quarters. Only one station was sampled during the winter quarter of 1975 (W2) and its ash-free dry weight value of 0.63 was very close to the 1978 value for the winter quarter (same station) of 0.88.
.I Diversity in the river stations was lower during the spring quarter of 1978 than during the same quarter of 1975. However, the creek stations for the two years were about the same for that quarter. Diversities for the summer quarters of 1975 and 1978 were similar, ranging from 1.6 (at S3) to 2.8 (at RS) fcr 1975 compared to 1.6 (at R2) to 2.3 (at RS) in 1978. While the diversities at Station R1 for the fall of 1978 and 1975 were almost identical (1.95 and 1.97, respectively),
that at Station R5 was much lower in 1975 than 1978 (fall quarter). Creek stations sampled in the fall generally had higher species diversities in 1975 than in 1978. Although only three stations are available for comparison, the spring I. 1976 quarter was roughly similar to the same quarter of 1978. The summer quarters, however, were totally dissimilar, with all stations in 1976 exceeding 2 million cells /10 cm while the 1978 values never exceeded 620,000. During the years 1976 and 1978, the river stations were similar for the fall quarters in that values of 3 million cells /10 cm were approached. However, the creek stations were drastically different. While the range of densities for the creek stations in fall 1978 varied from 25,510 to 73,980, the range for 1976 was 1 million to over 4 million. The upper river stations (R1, R2, and R3) were comparable during the winter quarters of 1977 and 1979; however, R4 was at least three times lower in 1979 than in 1977. The creek stations were likewise very low in comparison to the winter quarter of 1977. llm l The ash-free dry weight reached a maximum during the summer in both l years (1976 and 1978). However, the values for the spring, summer and fall quarters of 1976 were considerably above those of 1978. Whereas the maximum biomass reached at S3 in 1976 was 14.5 mg/10 cm , the maximum value for 1978 (at R2) was lI 3-7
e I ESPEY, HUSTON & ASSOCIATES, INC. 2 2.63 mg/10 cm , ,nte winter quarters, however, were reversed in that the 1979 winter quarter values exceeded those of 1977. Species diversity values were fairly even throughout the 1976-1d . .tudy - year with the majority of values above 2.0 and no real demarcation betwet, a c:ceek g and river stations, as occurred in the spring and fall quarters of 1978. 5 The dominance of diatoms in the periphyton during 1976-77 was com-plete to the point of almost eliminating the other algal divisions from the community. With the spring 1977 survey, however, the Chlorophyta and Cyanophyta began to appear in such numbers that they formed 1 small percentage of the periphyton population. The total periphyton density once again exceeded one cillion in the river stations during the spring quarter, surpassing by a factor of over 2 the 1978 values. The creek values for total periphyton were generally lower in 1978. So few diatometers were recovered during the summer quarter of 1977 that comparison with the summer quarter of 1978 is very hard. Generally, periphyton densities seemed to be higher during the summer quarter of 1977. m Periphyton densities in the creek stations during the fall of 1977 never exceeded 600,000 and hence were lower than the river station values of over 2 million. The fall 1977 values for the creek stations, however, were higher than the values for the corresponding stations in 1978. The 1978 winter quarter, in l comparison with the same quarter of 1979, is again reversed with respect to the river and creek stations. The 1979 river stations exceeded in density the 1978 river stations, but the 1978 creek stations exhibited lower densities than the 1979 stations. Unlike 1976 and 1978, the maximum biomass of periphyton in 1977 occurred in the spring. However, even the summer biomass of 1977 was larger than te maximum biomass values in the summer of 1978. Winter biomass values were slightly lower than the 1978 biomass of the same quarter. I 3-8 I I
I e ESPEY, HUSTON & ASSOCIATES, INC. Like 1976, species diversity generally remained above 2.0. The only noticable differences in diversity between the river and the creek stations occurred in the winter quarter, when the creek diversity indices were lower. Although there are significant differences between stations for the total I periphyton density as well as the component algal divisions (Table 3.19), there are more significant differences contributed by the variation in the annual samiIrg I program. ' Ibis holds true for all quarters except the winter, where regardless of the year, all samples were similar with respect to total periphyton and the component algal divisions. 3.1.3 Bimonthly Periphyton 3.1.3. Current Study Year The results of the bimonthly sampling program are presented in I Figs. 3.19 to 3.24 and Table 3.5. The pattern shown by the bimonthly samples is similar to the quarterly results in that the peak densities were recorded in the fall 'I (September through November). Small but significant quantities of Chlorophyta were observed in March and the Cyanophyta were observed in the months of July and September. No differences between right and left bank could be discerned for Stations R2 and R3. At Station R4, the Cyanophyta reached peak densities during July at 4L and during September at 4R. In terms of absolute abundance, biovolume peaks during the months of September and November were the reverse of density (Figs. 3.25 to 3.30, Table 3.6). At Stations 2R, 2L, 3R, 3L, and 4R peak densities were reached in November, but peak biovolumes were reached in September. At Station 4L, however, biovolumes were essentially the same for September and November, although the density peak W occurred in November. I I 3-9 m

'Ihere was not always good agreement between the dominant species observed during the bimonthly samples and the quarterly samples. The worst J
agreement seemed to be during the summer months and the best agreement was during the winter months (compare Tables 3.1 and 3.5, Tables 3.15 and 3.17). Biomass (ash-free dry weight) exhibited a peak in May and again in Il September. This was different from the quarterly values which reached a maximum 1 during the summcr. The July ash-free dry weights are actually closer to the
)
quarterly values for the winter. ! 11 The species diversity indices of the bimonthly samples followed closely the pattern set by the quarterly samples. After low values during the months of March and May, the diversity generally climbed to just above 2.0 and remained there I for the duration of the annual survey. Results of the one-way analyses of variance and Scheffe' Test on the bimonthly periphyton results are presented in Table 3.11. While there were no significant differences between densities of periphyton between stations for the g months of March and May, significant differences were obsers,ed for diatoms and 5 total periphyton for the months of July, September, November and January. In addition, the mean diversities of the Chlorophyta were significantly different between stations for the months of July and November. The mean densities of Cyanophyta were similar for all months except September. Generally, there were no significant differences between the "R" and "L" stations with the exception of 4L and 4R. During July these stations were different with respect to Chlorophyta, Bacillariophyta and total periphyton. In September, the same stations were different with respect to Cyanophyta. The mean densities of diatoms differed significantly between 3L and 3R in September and again in November for the Chlorophyta. W I I 3-10 I
I e ESPEY, HUSTON & ASSOCIATES, INC. The only possible upstream-downstream difference in total periphyton occurred in July when Station 4R was significant'.y different from 2R. Otherwise, no significant upstream-downstream differences were observed. Significant differ-l ences in dominaut species abundances were observed during each bimonthly period, but no particular pattern was evident in respect to either the stations or the species involved. Statistical analysis of cell volumes (Table 3.12) indicated that Nitzschia f linearis was significantly larger at 4R than at 2R during May. In January, Diatoma vulgare was significantly larger at 3R than at any of the other stations. 3.1.3.2 Comparison with Previous Years The two-way analysis of variance and Scheffe' testing between stations and years is reported in Table 3.20. There was only one month (March) in which there were no significant differences between stations. Chlorophyta had signifi-I' cantly different mean densities between stations during the n:onths of March, July, 1 September, and November. Mean densitics of diatoms were significantly different for the months of July, September, November, and January. Tota' periphyton mean densities were significantly different among stations during the months of July through January, inclusive. The peak densities (for both total periphyton and Bacillariophyta) for all March samples occurred during the second year. The mean densities of Chlorophyta gradually climbed to a peak during the fourth year. Yearly means for the May, July, September, November, and January 5 samples were consistent over the four-year study for both total periphyton and diatoms. The Cyanophyta reached a peak during the May samples in Year 3 along with the Euglenophyta. The peak for Chlorophyta for all the July yearly means was B 3-11
l e Il: ESPEY, HUSTON & ASSOCIATES, INC. 1 during the first year. The same was true of the Euglenophyta. July was also unique because during this month in the third year the dinoflagellates reached a peak ' unmatched at any other time during the study. Significant differences of mean densities between years of the dominant species were the general rule. Similarity between years occurred for the Pyrrophyta and Chrysophyta in all July samples, the Chrysophyta in all September samples, and the Cyanophyta in all November samples. The pattern of seasonal abundance of the total periphyton community during Year 4 with its consistent increase in density from MM to January makes this year more like Years 1 and 2 and dissimilar to Year 3, which had a maximum density in May. The same number of dominant species was observed during the current annual study as was observed in Year 3 (24). The numbers were 22 and 18 for Years 2 and 1, respectively. 'Ihe majority of dominant species were the same during all four years, but relative rankings varied widely (Table 3.30, First Annual Report; Table 3.17, Second, Third, and Fourth Annual Reports). Most of the differences in the dominant species lists were accounted for by species occurring sporadically or in relatively low density. g 5 The biomass value (ash-free dry weight) for March 1978 was only slightly lower than the corresponding months of 1977. However, biomass values for May, July, and September were much less in Year 4 than in Years 3,2, or 1. The species diversities for Year 4 were generally lower than those for Year 3 and were closer to Year 2. The gradual increase in species diversity which has characterized the study thus far was not continued in Year 4 (Table 3.8). The species diversities for Year 4 were generally lower than those for Year 3 and were closer to Year 2. The September 1978 value was, in fact, below that of October B 1975. Minimum diversities occurred in August, September, July, and March samples W in Years 1, 2, 3, and 4, respectively. E B 3-MI
I e ESPEY, HUSTON & ASSOCIATES, INC. 3.2 DISCUSSION Both the quarterly and bimonthly periphyton programs resulted in similar trends in total abundances, seasonal succession, and dominant species at the river stations. Seasonal succession during the current study year resulted in generally I rising total abundances from early spring through the fall. This pattern has been characteristic of periphyton growth in all of the study years except the previous one (EH&A 1978). Peak standing crops during the study year, which occurred during September or November, tended to be substantially higher than those observed during 1977-78, but were comparable to those observed in previous study years. These differences in seasonal succession, naturally, led to a large number of significant differences between this study year and the one irnmediately I irevious. The periphyton community continued to be dominated by the diatoms. As in previous years, centric diatoms tended to be dominant in the spring-summer .E "*"""*'****"""'"*"**^*"'****"d*** """*8*""""* ' "*"""** W diat2ms as dominants. The dominant species present continued to be signilar to those observed in other years, although considerable differences are evident in the relative rankings of these species between years. Unlike previous years, the Chlorophyta did not exhibit their usual peak in relative abundance during the summer. In both studies, but particularly in the bimonthly program, the Cyanophyta were observed to account for a substantial amount of total periphyton abundance during the summer and fall periods. 'Ihis is doubtless related to the unusually high relative abundance of the Cyanophyta observed in the phytoplankton during the summer of 1978. I The trend of increasing diversity values observed during the first three years of this study was not repeated during the current study year when diversity values did not increase over 1977-78. A large proportion of the dominant species found in the puiphyton continued to be forms tolerant of nutrient and/or organic enrichment (Palmer,1969; Lowe,1974). I 3-13 I
e I ESPEY, HUSTON & ASSOCIATES, INC. . The numerous differentes observed between stations during the current study and previous study years do not seem to show any pattern indicative of real differences in rivsr periphyton above and below the location of the intake structure . of the Byron plant. Differences in abundance and compositon between the river and creek stations, however, are quite evident during the study year,. with the creek stations showing very low abundances, mostly of pennate diatoms. No indications of left bank-right bank differences were seen in this year's bimonthly periphyton collection.
3.3 CONCLUSION
S
- 1) Patterns of seasonal abundance are again similar to Years 1 and 2, with a fall peak in standing crop rather than the spring abundance maxima observed in Year 3 and in the baseline study.
l
- 2) Standing crop Icvels are generally similar to Years 1 and 2.
- 3) The major group and dominant species composition of the peri-phyton has not changed substantially during the currc t study year, except that the expected Chlorophyta summer abundance peak did not occur. Instead a Cyanophyta maximum during the summer-fall period, paralleling that observed in the phytoplankton, was seen.
- 4) Species diversities for Year 4 were generally lower than those for I. -
Year 3 a id were closer to Year 2. The Rock River is sti11 considered to be eutrophic.
- 5) Large differences in abundances and species composition were observed between river and creek stations during the current year.
E E 3-14
I e ESPEY, HUSTON & ASSOCIATES, INO.
- 6) No upstream-downstream dWerences were apparent, and abun-dance differences between sides of the river were not noted. No differences were noted that could be attributed to construction.
t
.I
- 7) Biomass continues to coincide poorly with the other mearires of periphyton abundan :e.

e ESPEY, HUSTON & ASSOCl4TES, INC. I 4.0 ZOOPLANKTON 4.1 RESU1.TS I Year 4 zooplankton samples were collected on 23 May (spring),1 August (summer), 8 November (fall) 1978 and 20 February (winter) 1979 Materials and methods are presented in Appendix B. I 4.1.1 Data Analyses The results of zooplankton sampling during Year 4 of the monitoring I program are presented in Appendix A and at the end of this section. Appendix Table A.7 contains species density data (no./ms for station replicates by seasonal l quarters. Figs. 4.1 and 4.2 illustrate the seasonal absolute and relative abundance at Stations R2 and R5 respectively, of zooplankton categories into which taxa are group ed. The means graphed in Figs. 4.1 and 4.2 were obtained from Table 4.1, where the means, maxima, minima, and prcportions of categories and dominant species, with their associated variances are presented by station and quarter. Table 4.2 contains the species diversity and redundancy indices. Table 4.3 presents the results of a one-way analysis of variance (ANOVA) and Scheffe' multiple comparison of means performed on In(x+1)-transformed data. Results of chi-square tests of similarity in the distribution of dominants between stations are presented in , Table 4.4. A ranking of annual means and the range of quarterly means of all taxa achieving dominant status (5%) in any quarter are shown in Table 4.5. Table 4.6 presents the results of a two-way factorial ANOVA used to detect differences between stations across years and between the same seasons in the years across stations. I I 4-1 I
1 l e ESPEY, HUSTON & ASSOCIATES, INC. 4.1.2 Seasonal Patterns 4.1.2.1 Standing Crop The zooplankton standing crop community at both stations was composed primarily of rotifers during all quarters >xcept winter when copepods (mainly nauplii) predominated. These results correspond to those obtained in the first three years of this study (EH&A 1976, 1977, 1978) and in studies performed by Environ-mental Analysts (1973,1974-1975). The overall pattern of seasonal abundance most resembled Year 3. Density was greatest in spring and much reduced in summer, fall and winter at both stations. Winter densities at both stations in Year 4 were similar to winter densities in Year 3, whereas densities of the spring, summer and fall samples in Year 4 were much lower than Year 3 s,pring, summer and fall densities. In the spring of 1978, rotifers comprised the majority of the zooplankton community at both stations: 85% at R2 and 69% at RS (Fig. 4.1, 4.2, Table 4.1) while copepods (mainly naupliar larvae) comprised 14% and 30% of the community at R2 and R5 respectively. At both stations, Keratella cochlearis, Syncuaeta pectinata and copepod nauplii were the dominants (5% or more of the assemblage), with K_. cochlearis being the most dense at R2 and S. pectinata the most dense at R5. Mean densities at both R2 and P.5 were lower than the range of densities seen in the spring of Year 1 (1975) and Year 3 (1977), and higher than in Year 2 (1976). 4 The density at R2 (1.74x105 ) was greater than at RS (8.46x10 ) at was the case during the springs of all previous study years. Densities of categories and dominants were used to compare Stations R2 and R5 in one-way analyses of variance (AMOVA) and Scheffe multiple comparison of means. In the spring: significant (P < 0.05) differences were detected in the abundances of the categories " rotifers", " adult copepods", "cyclopoid copepodites", and " total zooplankton", and of the dominant Keratella cochlearis (Table 4.3) Chi-square analysis of the similarity of dominants between stations detected a signifi-cant difference (Table 4.4). 4-2 5

- Summer densities at both stations were much icwer thm in the spring (2.89x104 at R2 and 1.91x104 at RS) and lower than in previous summers. As in the spring, density at R2 was higher than density at RS, and rotifers were the primary group, comprising 74% of the community at both stations. Copepods represented 22% and 21% of the community at R2 and R5 respectively. Five species achieved dominant status at ea:b station. At both stations, four of the dominant species were the same (Pompholyx sulcata, Keratella cochlearis, Synchaeta stylata and nauplii. Monostyla closterocerca was a dominant species only at R2 while Conochilus unicornis occurred as a dominant only at RS. Pompholyx sulcata was the most abundant species at both stations accounting for 28% of the community at R2 and 25% at RS. The order of the remaining dominant taxa was dissimilar at the two stations and the chi-square test of similarity of dominants detected a significant I difference between stations (Table 4.1,4.4).
One-way ANOVA and Scheffs comparison of means detected significant differences in riean densities of total rotifers, copepods, nauplii, adult copepods, cyclopoid copepodites, and total zooplankton, and the dominants - Synchaeta stylata, Monostyla closterocerca and nauplii (Table 4.3). I The fall zoopankton community exhibited lower densities than in the summer: 2.67x104 at R2 and 7,23x103 at R5. As in both spring and summer, density at R2 was higher than at R5. Rotifers were the principal group comprising 99% and l 98% of the community at R2 and R5 respectively (Table 4.1). Keratella cochlearis I was the predominant species at both stations (84% at R2 and 64% at RS) followed by Synchaeta pectinata (10% and 14% at R2 and R5 respectively). Chi-square analysis for similarity of dominants detected a significant difference between stations (Table 4.4). One-way ANOVA and Scheffe Test (Table 4.3) detected significant dif-ferences in station means for two of six categories (total rotifers and total zooplankton) and one of two dominants (Keratella cochlearis). lI lI l 4-3 I
e I ESPEY, HUSTON & ASSOCIATES, INC. In the winter, densities at R2 and R5 were similar (1.88x10 at4 R2 and 4 2.04x10 at RS), dthough slightly higher than in Year 3, and much lower than in Years 1 and 2. In contrast to previous seasons in 1978 (Year 4), rotifers comprised only 12% and 7% of the community at R2 and R5 respectively, while copepods (mainly nauplii) became the most abundant organisms as in previous winters. Cope-pods accounted for 84% of the assemblage at R2 (79% nauplii) end 90% at RS (85% nauplii) (Table 4.1). Nauplii were the only dominants at both ctaticas. Chi-square analysis for similarity of dominants detected a significant difference between stations (Table 4.4). One-way ANOVA detected no significant differences in densities be-I tween stations. 4.1.2.2 Diversity Diversity (Table 4.2) exhibited lower values during the current year than in 1977 for all seasons excluding winter. The values of the diversity index recorded at 1"2 and R5 respectively, in the spring (1.209 and 1.553) were lower than all previous years. In summer, the values were the highest for Year 4, and similar to those of previous years. Fall and winter values in 1978 were relatively low, and somewhat similar to the values exhibited during Year 3. The extreme dominance of Keratella cochlearis at R2 in the fall, and of nauplii at both R2 and R5 in the winter, resulted in low diversities at these stations. l 4.1. 2.3 Annual Ranking l l For those organisms dominant at any station in any quarter, a quarterly and aneml mean density is calculated. Table 4.5 presents the rank ordered annual means of these taxa and the range of their quarterly means. All dominant organisms during Year 4 were rotifers except for copepod nauplii. Seven taxa reached dominant status during the fourth study year, compared to 12 taxa in Year 3,15 in Year 2 and 11 in Year 1. Two taxa (copepod nauplii and Keratella cochlearis) were 4-4 I
I e ESPEY, HUSTON & ASSOCIATES, INC. dominant during all four study years, six taxa werc dominant during three of the four study years, and four taxa were dominant during only two of the study years. I 4.1.3 Comparison Between Study Years Comparisons of stations and study years were also made by two-way ANOVA (Table 4.6). In these comparisons, log-transformed densities of major groups and dominant taxa were compiled for all four study years. These data were used to test for significant differences between stations and between similar seasons of different years. As in the one-way ANOVA, significant values of F in the ANOVI. were followed by the Scheff( Test to isolate significantly diffezent means at the 5% level (P < 0.05). The general tendency is that significant differences between stations are few, and usually involve sparse or seldom occurring taxa; while the comparisons between years detect significant differences in most cases. I 4.1.3.1 Spring
^
l In comparisons using data from the spring seasons of the first four years of the study, only three categorical groups, and four rotifer taxa were found to exhibit significant station differences. All 10 categories and all nine dominants used to compare years, however, were indicated as having significant " year" differences by ANOVA. In all cases, the Scheff( Test separated Station R2 and R5 by significant amounts, and in most cases, the Scheffi Test separated each year from the other three by significant amounts. Only the very scarce harpacticoid copepodites failed to exhibit significant differences between any two years. I 4.1.3.2 Summer Cemparisons using summer data detected significant differences be-tween stations in the densities of five zooplankton categories (rotifers, copepods, nauplii, cyclopoid copepodites, and "other") and eight of 16 dominant species.

l g i ESPEY, HUSTON & ASSOCIATES, INC. cant differences in the densities of all categories except cladocerans and calanoid copepodites, and significant differences in the densities of all dominants. As in spring, in the majority of cases, the Scheffi Test t.eparated the two stations (R2 and RS) by significant amounts and each year from the other three by significant amounts. t i 4.1.3.3 Fall
- 5 Categorical comparisons of fall zooplankton density between Stations R2 and R5 detected significant differences only for rotifers and total zooplankton. Of the 10 dorninants tested, only three rotifer species had significantly different densities at the two stations. When yearly data were tested for differences in mean densities by two-way ANOVA and Scheffi Test,17 of 18 categories and dominants had significant differences between years. In over half the cases, significant differences were noted between years.
4.1.3.4 Winter No significant differences between Stations R2 and R5 were detected in winter data using either categories or dominant species in the two-way ANOVA. When the winter data was used to test for differences between years however, the densities of all categories and dominants exhibited significant differences. In two of the 12 Scheff8 multiple comparisons, there were significant differences between all four years. In three of the Scheffi comparisons of means, Years 1 and 2 were inseparable; in five cases, Years 3 and 4 were inseparable; in one case, both Years 1 and 2 and Years 3 and 4 were inseparable; and in one case (the scarce calanoid copepodites) only Years 1 and 2 were significantly different. I I 4-6 I I
y I e ESPEY, HUSTON & ASSOCIATES, INC. 4.2 DISCUSSION 4.2.1 Spring I Spring samples were collected during a period of relatively low popula-tion density. This is in marked contrast to the high density of zooplankton collected
. in the spring of 1977 as well as in the spring of 1975. Diversities at both stations were lower during spring 1978 than in any previous spring sample, reflecting strong dominance by a few species (i.e.) Keratella cochlearis, Synchaeta pectinata and nauplii. The spring community was dominated by rotifers as in all previous years.
Community structure was more similar to that of spring 1975 than 1976 or 1977 due to the importance of nauplii, along with the dominance of the rotiferan elements. Spring sampling during 1978 was accomplished during a period of relatively normal high spring flows which is a probable factor for the low densities at this time. I 4.2.2 Summer Zooplankton density in summer decreased greatly from spring as was the case in 1975 and 1977, with rotifers dominating as in all previous years. Diversity at both stations increased from spring. This kind of decline in zooplankton numbers during suminer months is typical of large bodies of water (Hutchinson 1967), although in this case, low zcoplankton density was probably due to increased flows i and high silt load evident at the time of sampling (Williams 1967). The summer sampling effort was undertaken following an unusual period of frequent heavy rains, , resulting in extremely high flowc and extensive flooding, scouring the river and diminishing the zooplankton population. 4.2.3 Fall The fall 1978 samples indicated that the zooplankton population was in a depressed co idition. Both relatively low densities and diversities were evident in the fall of Year 4, and may be indicative of nor 1 post-peak conditions. Declining I 4-7 I
e ESPEY, HUSTON & ASSOCIATES. INC. temperatures during November may have had an inhibitory effect on the zoo-plankton population, along with previously high flows and subsequent fluctuating water levels. Rotifers were overwhelmingly dominant during the fall as in previous seasons of 1978 and previous study years. 4.2.4 Winter Winter samples were collected during an extended period of cold weather, when the river was covered by approximately 30 centimeters of ice and a further cover of abou. ,0 centimeters of snow. Water temperatures remained around freezing and little light penetrated through the ice and snow in the study area. Phytoplankton production was thereby severely inhibited and this resulted in low zooplankton densities (as in the winter of Year 3). The winter community was comprised almost totally of copepod nauplii, as reflected .'n the low diversity indices. The conditions of winter Year 4, were very similar to those of winter Year
- 3. Densities and diversities of the zooplankton community sampled during Year 4 were only slightly higher than densities and diversities of the Year 3 winter community. The chi-square tests of winter 1979 data detected significant dif-ferences in community structure, but the value of chi-square was much lower than in other seasons, indicating that the structure was much more similar in winter than at other times.
4.3 CONCLUSION
S
- 1) No construction-related effects on the zooplankton community of the Rock River were detected in the ccrrent study year.
- 2) The zooplankton community of the Rock River continued to display a fauna typical of large rivers and impoundments and as in all previous atudy years was strongly dominated by rotifers in all but the winter quarter.

I e ESPEY, HUSTON & ASSOCIATES, INC.
- 3) Sample Stations R2 and R5 were similar in terms of community structure during all seasons, although densities at R2 throughout the year were higher than those at R5 except during the winter.
- 4) Environmental conditions, including high flow rates and turbidity, I (i.e.) high spring flows, unusual summer flooding and slightly lower temperatures probably contributed to the overall low densities seen during 1978.
- 5) Sample years as expressed in comparisons of similar seasons are typically different, and the differences noted between comparable seasons, both in community density and diversity as well as physical parameters of importance, illustrate a range of variation to be expected in quarterly data sets.

I e ESPEY, HUSTON & ASSOCIATES, INC. I 5.0 BENTHOS I 5.1 RESULTS Year 4 natural substrate benthos samples were collected quarterly from river and creek stations on 23 May (spring),1 August (summer), and 8 November (fall) 1978. No samples were collected in the winter due to river ice. Artificial substrate (Hester-Dendy) samples were collected monthly during April through September 1978. Sampling dates were 11 and 17 April, 20 May,13 June,19 June.14 August, and 19 September. Revision of nomenclature has resulted in name changes for several of the dominant dipteran taxa. These changes, including names used in previous annual reports and names used in the present report, are listed in Appendix Table B.3. Materials and methods are presented in Appendix B. 5.1.1 Data Analyses Absolute and relative abundances of the most common benthic taxonomic groups in the natural substrate program are graphed according to station in Figs. 5.1 through 5.8. Absolute and relative abundances observed at each artificial substrate station are graphed in Figs. 5.9 through 5.14. Table 5.1 presents, by quarter and station, the average and range of densities for total number, dominant species, and major groups of benthos in the natural substrate program. Diversities and redundancies are listed by replicate for each natural substrate sample in Table 5.2. Average and range of particle sizes (proportional composition) for each station and quarter are shown in Table 5.3, while sediment organic carbon I (% TOC) from each replicate is presented in Table 5.4. The average and range of density summaries for each station and month of the artificial substrate program are presented in Table 5.5. Diversities and redundancies for the artificial substrate samples are presented in Table 5.6. The results of the one-way ANOVAs and Scheff8 Tests for between-station differences in population sizes in the natural substrate program are shown in Table 5.7, and statistical testing for between-station

Table 5.14 contains the results of' the two-way E ANOVAs and appropriate Scheff( Tests on the count data from the natural eubstrate program, while the results of these tests applied to sediment TOC are shown in Table 5.15.

Appendix A.8 and A.9 for the natural substrates and in Appendix A.10 for the artificial substrates. 5.1.2 Natural Substrates 5.1.2.1 Seasonal Patterns 5.1.2.1.1 Standing Crop I Total standing crop of natural substrates benthos during Year 4 tended to I vary seasonally, depending primarily on flow regimes and substrates at each station. Population densities generally tended to be higher at downstream stations compared with upstream river stations (Table 5.1), corresponding with lower current velocities (Table 7.3) and finer sediments (Table 5.3) downstream. Density at river stations R1, R2, R3, and R5 decreased from spring to summer (Table 5.1, Figs. 5.1-5.8), corresponding to higher than normal summer flows which tended to scour finer substrates and benthic organisms, especially at upstream stations. At Woodland Creek Station W2, creek mouth Stations S3 and S5, and at Station R4, howe. , density increased from spring to summer. I-In fall when river flow declined, an increase in benthic standing crop was observed at all stations except R1 and R4. At two stations, R2 and R3, increased Ill 5-2 I I; 1

; standing crops were correlated with increased percentages of fine substrates from summer to fall.
Spring standing crop was lowest at Station W2 (33/m ) and ranged from 297/m (RI) to 2272/m (R2) at other stations (Table 5.1). In summer, the density declined at R1, R2, R3, and R5, increasing only at R4, S3, S5 and W2. The range in densities was from 124/m2 (R1 and R2) to 2894/m% (SS). A rather drastic population reduction was observed at Station R2, which was one of the most dense stations in spring but one of the least dense in summer. This reduction is attributable to I scouring of substrates by high river flows. The range in natural substrates benthos standing crop for fall was from 81/m (RI) to 3243/m (SS). The highest densities overall (spring, summer, fall) were observed at R5 and SS, where sediments tended to be finest. The lowest densities occurred at R1, where substrates were coarse, and at W2, probably due to habitat differences. I Significant station differences for total benthos were detected by Scheff8 Test between W2 and all other stations in spring (Table 5.7). In summer the major differences involved R1 and R2, which tended to have significantly lower densities than R4, S3 and SS. Densities at Station R1 were significantly lower compared with most other stations duris- fall. Oligochaeta was overall the most abundant group in quarterly benthos ( samples at all stations except R1 and W2. Diptera was the second most important group at these stations, particularly during spring and fall. Station W2, like river stations, was predominated by Oligochaeta during summer, but the Diptera was the I dominant group in spring and fall. Dominants at R1 changed ouarterly, but overall this station appeared to be severely stressed by high river flows, resulting in extremely low densities (Fig. 5.1). Most significant station differences in Scheff( Test of dominants were between Stations R1 and W2 campared with other stations, and involved primarily the category Oligochaeta, particularly during sprmg and fall (Table 5.7). l 5-3
g I. ESPEY, HUSTON & ASSOCIATES, INC. By far the mor - abundant and widely distributed taxon in benthos samples was Immature Tubificidae, which overwhelmingly predominated at most statims during each quarter (Table 5.1). Several species of Limnodrilus (cervix, maureensis, spiralis) comprised the remaining dominants at most stations. Only a few dipterans obtained dominant status, the more important of which were l Polypedilum illinoense in spring, and Cryptocladopelma sp. and Chironomus thummi I l group in fall. In terms of absolute abundance, Diptera were most important at SS and WZ in fall, the predominant taxon being Chironomus thummi group. Most significant differences detected by Scheffe' Test of means for dominant taxa involved Stations R1, W2, S5 and S3, and the taxa Immature Tubificidae, Limnodrilus cervix, L. maumeensis, Unidentifiable larval fish, and Chironomus thummi group. Immature Tubificidae and Limnodrilus spp. tended to be significantly less abundant at R1 and W2 compared with other stations in all g quarters (Table 5.7). In spring Potamanthus sp. (Ephemeroptera) was significantly 5 ( more abundant at R1 and S3 compared with other stations. Unidentifiable larval fish were significantly more abundant at W2 than all other stations in summer. In fall, Cryptocladopelma sp. tended to be significantly more abundant at R1, R2 and R3 compared with all other stations. Chironomus thummi group was significantly more abundant at 35 and W2 in fall compared with all other stations except R5. 5.1.2.1.2 Dominant Species Comparisons Chi square tests of similarity for dominant species detected significant differences among all stations in spring and among most stations in summer and fall. g l Only one comparison in summer (R3 vs. R4) and two comparisons in fall (R3 vs. R4, 5 R3 vs. S3) (Table 5.10), were not significantly different. 5.1.2.1.3 Species Diversity I Species diversity was higher overall in spring and fall compared with I summer, although diversities at three stations (R5, S3, W2) we. highest in summer. , l' 5-4 I.
I e ESPEY, HUSTON A TSSOCIATES, INC. In spring, diversity ranged from 0.520 (W2) to 1.346 (SS) (Table 5.2). Summer diversities were lower at most stations, ranging from 0.273 (R3) to 1.082 (S3). Diversity increased again in the fall, ranging from 0.451 (W2) to 1.385 (P.2). Only I one stat!on, S3, consistently maintained a diversity greater than 1.000 in all quarters. 5.1.2.1.4 Sediment Analyses Sediment particle size was predominantly fine sand at most river stations during spring, summer and fall (Table 5.3). However, Station R1 had coarse sediments, predominantly gravel and coarse sand, in spring and summer, while substrates at R2 and R3 in spring were predominantly silt. Station S3 apparently had the greatest range and seasonal variability in particle size and also demon-strated considerable variation among replicates. The finest substrates overall occurred at SS, predominantly silt and clay. Overall the highest TOC values were found in spring, ranging from 0.09% (R4) to 3.40% (R2) (Table 5.4). Summer and fall ranges were very similar, 0.04-1.87% and 0.07-1.87%, respectively. Station S5 tended to have the highest percent TOC, especially in summer and fall. Statistically, Stations R2, R3 and SS demonstrated significantly higher sediment TOC in sp-ing compared with other stations, but in summer few differ-ences were detected by Scheffe analysis (Table 5.8). In fall, one-way ANOVA's indicated no significant station effects. 5.1. 2.2 Annual Ranking of Dominants , Dominants in natural substrates in Year 4 were sitnilar to those of previous years, with members of the Diptera and Oligochaeta comprising the majority of taxa (Table 5.12). The highest ranking of 21 dominants in Year 4, based on annual mean abundance, was Immature Tubificidae. Chironomus thummi group, I m
e I ESPEY, HUSTON & ASSOCIATES, INC. the most abundant dipteran, was ranked third in the table, while Hexagenia limbata was the most abundant ephemeropteran and ranked ninth among the dominants. Of the top ten dominants, four were oligochaetes, five were dipterans and one was an ephemeropteran. 5.1. 2.3 Comparison Between Study Years Two-way ANOVAs indicated many significant year and station effects on the mean density of total benthos and dominant taxa during the three quarters. By Scheffi Test, more station differences were detected for total benthos in fall compared with spring and summer, while year effects were more pronounced in spring and summer samples (Table 5.7). Station WZ most consistently demonstrated a significantly lower mean total density compared with cther stations, although R1 in summer and R2 and S3 in fall tende1 to have lower densities compared with most stations. Mean densities of dominant taxa typically were significantly different at - Stations W1 (spring), W2, S3 and R1 compared with river stations. These stations tended to have lower densities of the major dominants found at moat river stations, but were distinguished by the presence of several taxa which were scarce or absent at other stations. By Scheffi Test, more significant differences in total density were detected among Years 1, 2 and 3 than in comparisons of these years with Year 4 (Table 5.7). Overall, Year 1 tended to have the lowest mean total density and Year 2 the highest. Yearly trends for dominant taxa tended to follow those for total benthos. I; , II , Il ; I 5-6 I

HUSTON & ASSOCIATES, INC. 5.1.3 Artificial Substrates 5.1.3.1 Seasonal Patterns 5.1.3.1.1 Standing Crop I Macroinvertebrate densities on artificial substrates tended to be the highest in summer and lowest in spring, with intermediate fall densities. Standing crop increased at all stations from April (333-1358/m ) to June (8054-23,079/m 2) and July (3196-22,746/m ) (Table 5.5, Figs. 5.9-5.14). By August, density had declined at all stations except 3L, although it remained well above that for May. Densities in September were similar to August, except at 4R where density' declined to about 50% of the August crop. In September, all stations had similar densities which ranged from 5058 to 7212/m . High river flow undoubtedly reduced macroinvertebrate population densi-I ties, which were lower in July and August, during and af ter unusually high and late summer flows, than in June, before the peak flows occurred. Significant station effects on total benthos were detected by one-way ANOVA for .he months of April and July. By Scheffi Test, only a few between-station differences were indicated in July (2R versus 3L and 4R) and none in April (Table 5.9). Dominant macroinvertebrate groups on artificial substrates varied sea-sonally. Diptera was the dominant group at most stations in April-May, fish eggs in June-July, and Trichoptera in August-September. Ephemeroptera attained their I highest relative abundances in fall, co-dominating with Trichoptera at most stations (Figs. 5.9-5.14). Monthly changes in population size of each major group are more apparent if absolute, rather than relative abundances are considered. From fairly I

e I ESPEY, HUSTON & ASSOCIATES, INC. Iow densities in April (262 to 1275/m ), the dipteran population doubled or tripled in density (1912 to 3321/m ) by June (Table 5.5). Dipterans declined slightly in July, and by August had returned to the low densities observed in spring. In September Diptera increased at all stations except 2L, of ten approaching densities observed in June. Trichoptera had lower standing crops in all months except August and September compared with Diptera. They generally increased in abundance until June, declined slightly in July, and then increased to become the most abundant group in Aug"d and September. Fish eggs appeared in high numbers in June, and dominated at all stations except 3L during this and the following month. Numbers declined rapidly by August, probably as a result of reduced spawning, and none were collected in September. Ephemeroptera had very low densities in April and May, increased gradually at ruost stations in June and July, and attained their highest densities in August and September. By August, they were the second most abundant group af ter Trichoptera at most stations, and remained so through September. Dominant taxa varied monthly on artificial substrates at all stations. In April, six different dipteran species were included among the dominants, shifting to a single species, Simulium Jenningsi, in May (Table 5.5). Fish eggs dominated at most stations in June and July (except 3L in July), with Polypedilum illinoense and Simulium jenningsi as the second dominants in these two months, respectively. By August, fish egga had declined at most stations, but remained the primary dominant at 2R and 4R. Cheumatopsyche sp. dominated at most stations in August and at 2L and 3L in September, Tanytarsus (Rheotanytarsus) sp. dominating at all other stations in September. Statistically significant between-station differences in major categories were detected by one-way ANOVA during all sampling months, however, these differences were unconfirmed by Scheffe Test during April and May, and only minor differences were detected during September (Table 5.9). On the other hand, Station ZR tended to have significantly lower densities of Ephemeroptera, Trichoptera, Diptera and total Insecta compared with some other stations during June-August, and had significantly more fish eggs compared with Stations 3L and 4R during July. I 5-8 I
I e ESPEY, HUSTON & ASCOCIATES. INC. Relatively few significant station differences were detected by Scheffe analysis of the dominant taxa, however, Station ZR tended to have significantly fewer Simulium Jenningsi and Hydropsyche orris than other stations in July, and fewer Baetis sp. in August (Table 5.9). In September, significantly lower numbers of Polypedilum illinoense were found at both 2R and 2L compared with most other stations. 5.1.3.1.2 Dominant Species Comparison , Chi-square tests of similarity indicated significant differences between stations for most pairwise comparisons within each monthly data set. Only two comparisons in the May set (2R vs. 3R, 2L vs. 3L) and one comparison in the June set (2R vs. 4R) were not sigr ificantly different (Table 5.11). I 5.1.3.1.3 Species Diversity Species diversity indices indicated seasonal trends in community struc-ture, the highest diversities occurring in spring and fall and the lowest in summer. Diversity remained above 1.000 at all stations during April, May and August, dropping below 1.000 only at two stations in June (4R, 4L) and July (2R, ZL) (Table 5.6). A substantial increase was observed in August, with maximum diversity occurring at all stations in September (2.293-2.520). l I 5.1.3.2 Annual Ranking of Dominants Dominants on artificial substrates in Year 4 were, with a few exceptions, similar to previous years. Members of the Diptera, Trichoptera and Ephemeroptera comprised the majority of the 20 dominant texa, although fish egos had the highest annual mean abundance overall (Table 5.13). The highest ran'<ing dipteran, Simulium jenningsi, ranked second among the dominants, while Cheuraatopsyche sps, the most [ abundant trichopteran, ranked third and Baetis sp., the mest abundant ephemerop-teran, ranked ninth. Of the top nine dominants af ter fish eggs, three were Diptera, four were Trichoptera and two were Ephemeroptera. 5-9
e I ESPEY, HUSTON & ASSOCIATES. INC. 5.1.3.3 Comparison Between Study Years l Two-way analysis of variance of monthly benthos totals indicated , statistically significant station effects during April, July and September, and l significant year effects during all months (Table 5.16). Relatively few significant g between-station differences in total benthos were detected by Scheffi Test, 5 although Station 2L in September had significantly lower total densities of macro-invertebrates compared with most other stations. Many significant between-year differences in total benthos were detect-l ed by Scheff( Test of means (Table 5.16). Overall, Years 2 and 3 tended to have significantly higher macroinvertebrate densities than Years 1 and 4. In the two-way analysis of dominant species, station effects were significant in about half the cases, while year effects were significant in almost aU 1 cases (Table 5.16). In comparisons of dominants by Scheffi Test, more significant station differences were detected in summer and fall than in spring. Stations 2L, 3L ' l and 4L were most frequently segregated by Scheffi Test from right-bank stations l and from each other on the basis cf dominants. Many significant differences between years were detected for dominants by Scheffi test, with different dominants tending to maximize their densities in different years (Table 5.16). For example, Potamyia flava and Hydropsyche orris tended to be most abundant overall in Year 2, while fish eggs and Glyntotendipes 1 dreisbachi were most abundant in Year 3, and Simulium jenningsi in Year 4. Abundances of other taxa (e.g. Polypedilum illinoense and Stenonema integrum) remained relatively uniform from year to year, although their seasonal abundances varied. 5.2 DISCUSSION Total abundance of natural substrates benthos in Year 4 was inter-mediate between the low densities observed in Year 1 and the somewhat higher l' 5-10 I
I e ESPEY, HUSTON & ASSOCIATES, INC. densities of Years 2 and 3. The major factor contributing to the lower densities was the unusually high river flow during spring and summer. Densities were similar on the average from season to season, although they tended to be lower, especially in the river, during summer. I Lower inacroinvertebrate densities were consistently observed at Sta-tions W2, S3 and R1 compared with other stations. Low densities at W2 probably I corresponded to habitat differences in Woodland Creek compared with the Rock River. Station S3, at the mouth of Woodland Creek, demonstrated a greater seasonal variation in substrates than river stations or SS, which probably contributed to the overall low densities at S3. Station R1, the most upstream river station, had coarser substrates than ' downstream stations due to higher current velocities, and scouring of substrates was apparently limiting macroinvertebrate populations at this station. Station S5, at the mouth of Spring Creek, had the highest density of benthos overall, corresponding to the consistently fine silty clay substrates. As in previous years, the natural substrate samples at most stations, except R1 and W2, were dominated by Oligochaeta and Diptera. Immature I Tubificidae was the highest ranking dominant overall for the fourth consecutive year, while Chironomus thummi group remained the highest ranking dipteran, as in Years 2 and 3. As in previous years, Station W2 was differentiated from all other stations by a different macroinvertebrate assemblage. Dominants at R1 also differed from other river stations, and chwged seasonally. Species diversity of the benthos was somewhat lower in Year 4 compared with Years 1, 2 and 3, resulting from the higher relative abundance of Oligochaetc and lower relative abundance of Diptera in Year 4. As in natural substrate samples, macroinvertebrate densities on artificial I substrates were, on the average, lower in Year 4 than in Years 2 and 3 but higher than in Year 1. Only one station, 2R in June, demonstrated significantly higher total densities than others (3R, 4R). On the average, densities on artificial substrates were lowest in April and May and highest in June and July. I sm
e I ESPEY, HUSTON & ASSOCIATES, INC. The predominant factor affecting macroinvertebrate densities and com-munities in Year 4 was the unusually high flow. The effects of river flow in 1978 on the artificial substrates fauna may be demonstrated by a comparison of the annual ranking of dominants for the four study years. In the first three years, the top five dominants have most of ten included fish eggs, Tanytarsus (Rheotanytarsus) sp., Hydropsyche orris, Potamyia flava and Glyptotendipes lobiferus. In Year 4 the top five dominants were fish eggs, Simulium jenningsi, Cheumatopsyche sp., Polypedilum g illinoense, and Tanytarsus (Rheomaytarsus) sp. Probably the most notable change 5 from previous years was the increase in the absolute and reaative abundance of Simulium Jenningsi. This species had appeared only once before, in 1976, in the dominant ranking tables, when it ranked number 15 of 19 dominants. Members of the family Simuliidae, which includes Simulium, are generally adapted to habitats with high current velocities and stable substrates such as that provided by the Hester-Dendy samplers. As in previous years, adhesive fish eggs remained abundant on Hester-Dendies in spite of high flows. Gradualincreases in fish populations since the 1975 flood event had resulted in increasing fish egg densities in Years 2 and 3, and in Year 4 the annual mean density of fish eggs on Hester-Dendies was about 80% of the mean density in Year 3. In general, density of dominants on artificial substrates in Year 4 did not I demonstrate significant station differences. How ever, Station 2R tended to differentiate from other stations in statistical comparisons of dominant taxa, as it did for total abundance. No consistent patterns of right and lef t bak differences were seen in Year 4. Species diversities in artificial substrate samples were somewhat lower on the average in Year 4 compared with Years 1, 2 and 3. However, diversities increased in August and Septe mber, and at most of the stations, September diversities were the highest so far reported in the present study. Similarly high diversities were reported in August 1975, another year of unusually high flows. I I 5-12 I

5.3 CONCLUSION
S
- 1) Macroinvertebrate densities in both the natural and artificial substrate programs in Year 4 were intermediate between the low densities of Year 1 and the higher densities of Years 2 and 3. High summer flows were the major factor contributing to low overall densities.
I 2) Altbough the rank order of dominants has varied somewhat from year to year, the dominant taxa in Year 4 were similar to previous years in both the natural and artificial substrates programs. The major exception was the unusually high abundances of Simulium Jenningsi which coincided with the peak flow periods of May and July.
- 3) As in previous years, Station W2 was characterized by low densities and a different taxonomic assemblage in natural substrate samples, which was attributable to habitat differences between Woodland Creek and the Rock River.
I 4) Although not significantly different, Station S3 tended to have lower total abundances of benthos than river stations except RI. Substrates tended to vary more at S3 than in the river.
- 5) Station SS at the mouth of Spring Creek tended to have significantly higher densities of total benthos, Oligochaeta and Diptera, especially compared with l Stations R1, R2 and W2. High densities at S5 are attributable to finer (silty clay) substrates than occurred in the river.
t
- 6) Station R1, and to a lesser extent R2, tended to have significantly lower abundances of total benthos and oligochaetes compared with R3, R4, R5, and S5, correlating with coarser substrates at these stations. Dominant taxa at R1 differed from all other stations during spring, summer and fall sampling.
lI 5-m
e I ESPEY, HUSTON & ASSOCIATES, INC.
- 7) In the artificial substrates program, Station 2R most frequently was distinguished by statistical tests, most of the differences involving relative abun-dances of the dominant taxa, although dominant taxa were similar for all stations.
- 8) In Year 4, no changes in the macroinvertebrate fauna could be detected which were attributable to plant construction.
