ABSTRACT Forty-three species of fish representing 13 families were collected from the Kankakee River and Horse Creek in 2010. Neither the river redhorse (Moxostoma carinatum), currently listed as threatened in Illinois (Illinois Endangered Species Protection Board, 2009) or the pallid shiner (Notropis amnis), currently listed as endangered in Illinois, were collected in 2010. However, an unidentified lamprey species was collected during one of the electrofishing sampling efforts. This represents the first time that a lamprey species (Petromyzontidae) has been observed during the long-term monitoring program near Braidwood Station. Electrofishing and seining efforts resulted in the collection of 3798 fish weighing 173.1 kg. Spotfin shiner (23.0%), longear sunfish (16.0%), bluntnose minnow (15.7%), bullhead minnow (10.5%), largemouth bass (6.3%), and sand shiner (5.6 %) were the most common species collected.
Eight (0.21%) of the 3798 fish collected exhibited some form of external anomaly. Lesions (40.0%), eroded fins (30.0%), and anchor worm (30.0%) accounted for all of the ten anomalies observed.
Tumors, malformations, fish lice, leeches, black spot, and cysts were not observed on any of the 3798 fish collected in 2010. The low incidence of DELT (Deformities, Eroded fins, Lesions, and Tumors) anomalies noted during these studies continues to indicate that the fish assemblage in this portion of the Kankakee River is in very good condition during the August sampling period.Mean relative weights (Wr) of fish within the study area ranged from 87.2 for bigmouth buffalo to 115.1 for gizzard shad. With the possible exception of a few individuals, the remaining fish that were collected were in good to excellent condition during the August sampling period. The species most commonly afflicted with anomalies were channel catfish, rock bass, and freshwater drum (2 individuals each). The highest percentage of fish with anomalies occurred at Location IL where one (0.85 %) of the 118 fish examined exhibited some form of external anomaly.Spawning success and population structure were evaluated for four selected species. Recruitment for longear sunfish, smallmouth bass, and rock bass appeared to be weak in 2010 based on ii HDR Engineering, Inc.
seining and electrofishing data. In contrast, largemouth bass recruitment appeared to be very strong. As a point of interest, due to recent stocking efforts in the Kankakee River by the Illinois Department of Natural Resources, twenty walleye measuring from 135 to 586 mm in total length were collected during the 2010 sampling program. Seventeen of these fish (85.0%) were most likely Age 0 fish that measured from 135 to 193 mm. The remaining three fish measured 276, 439, and 586 mm, respectively.
Based on length frequency data, at least four age classes of walleye were collected during 2010.No identifiable change in the fish community has occurred due to the operation of the Braidwood Station intake and discharge.
Fish communities sampled in the vicinity of the intake and discharge have occasionally resulted in the capture of fewer species than those observed at the other locations.
Variability in the catch rate, species diversity, and condition of fish by location appears to be related to differences in habitat rather than Station operation.
In particular, extensive beds of aquatic macrophtyes have. developed near the Station in recent years, which can influence the ability to capture fish and perhaps alter species composition over time. Based on visual observations, there was a substantial decline in aquatic macrophytes within the study area during August 2009 and 2010 compared to 2007-2008.
The reduction in aquatic vegetation in 2009 and 2010 likely influenced the numbers and composition of the fish collected, primarily sunfish species and other taxa that utilize this habitat for spawning and protection against predation.

1.0 INTRODUCTION
Construction of the Braidwood Nuclear Generating Station and its associated riverside intake and discharge structures provided an opportunity to gather fisheries information from the Kankakee River near the Station. These studies were initiated to determine the effects of construction and plant operation on the river. Units I and II began commercial operation on 29 July and 17 October, 1988, respectively.
The Kankakee River is a seventh order stream that encompasses a drainage area of approximately 13,400 km 2 (Healy 1979). The geology, hydrology, and water quality of the Kankakee River combine to form a diversity of habitats and aquatic life, creating one of the finest rivers in Illinois (Smith 1971, Skelly & Sule 1983, Brigham et al. 1984). The river is a scenic, cultural, recreational and industrial resource (Barker et al. 1967, Graham et al. 1984) that has remained relatively unaltered while still meeting the needs of the public, municipalities, and private interests.
The Braidwood Station Aquatic Monitoring Area, near Custer Park, Will County, Illinois, consists of a 2.5-km reach of the Kankakee River and its tributary, Horse Creek (Figure 1-1) and is located 23.5 km upstream from the confluence of the Kankakee and Des Plaines Rivers (Kwak 1991). The monitoring program in the Kankakee River and Horse Creek near the intake and discharge structures was initiated by Westinghouse Electric Corporation in October 1972 and continued through March 1973. A report, issued 30 November 1973, discussed results and projections of construction impact. Results were also discussed in the Braidwood Station Environmental Report and the Braidwood Final Environmental Statement.
The Illinois Natural History Survey annually conducted sampling near Braidwood Station from 1977 through 1990, excluding 1980 when no sampling occurred.
In 1991 and 1992, the program was continued by Lawler, Matusky & Skelly Engineers (LMS), using a modified sampling design that included a reduction of electrofishing effort by one-half (LMS 1992). The sampling program was conducted for one year by Environmental Science & Engineering in 1993. Following 1993, LMS again conducted sampling on the Kankakee River from 1994 to 2004. In 2005, LMS 1-1 HDR Engineering, Inc.

Sampling has been conducted by HDR since 2005. The summer sampling program near Braidwood Station has remained relatively unchanged since 1991. This continuing database allows documentation of environmental changes, the resulting response of the fish community, and an estimation of the environmental quality of the river.The objectives of the 2010 program were to: 1. Evaluate the year-to-year changes in the fish populations of the Kankakee River, including their annual reproduction, recruitment, and condition.
- 2. Provide a basis for examining the effects of Station operation, if any, on the Kankakee River and Horse Creek fishery.1-3 HDR Engineering, Inc.
2.0 METHODS 2.1 Electrofishing Electrofishing was conducted using a boat-mounted boom-type electrofisher utilizing a 5000 watt, 230 volt AC, 10.amp, three-phase Model GDP-5000 Multiquip generator equipped with volt/amp meters and a safety-mat cutoff switch. The electrode array consisted of three pairs of stainless steel cables (1.5 m long, 6.5 mnn in diameter) arranged 1.5 m apart and suspended perpendicular to the longitudinal axis of the boat 1.5 m off the bow. Each of the three electrodes was powered by one of the phases. Electrofishing samples were collected on 2-3 August during the first sampling effort and on 16-17 August during the final survey period.Sampling was conducted at five locations in the Kankakee River and at one site in Horse Creek (Location 2). Each sampling location (except for Location 2) consists of two stations, designated by the location number and "R" or "L", indicating the right or left side of the river as one looks upstream (Figure 1-1 & Table 2-1). Electrofishing was conducted along the shoreline on each side of the river at Locations 1, 3, 4, 5, and 6. At Locations 1, 5, and 6, each station [(L)eft and (R)ight banks] was electrofished for 30 minutes. Because of the close proximity of Locations 3 and 4, sampling boundaries for those locations were smaller and sampling duration was reduced accordingly to 15 minutes. In Horse Creek, the entire width of the stream was electrofished for 30 minutes from its mouth to a point approximately 75 m (250 ft) upstream.
Electrofishing was conducted such that the first "run" at each location was in a downstream direction through the middle of the shocking zone. The second "run" was conducted in an upstream direction, adjacent to the first "run" and as close to the bank as water depth allowed. The third "run", if necessary, was made in a downstream direction outside of, but adjacent to, the two previous runs (Figure 2-1). Sampling was restricted to the hours between one-half hour after sunrise to one-half hour before sunset.2-1 HDR Engineering, Inc.

ILLUSTRATION OF ELECTROFISHING BOAT PATH DURING SAMPLING IN THE BRAIDWOOD STATION MONITORING AREA.2-3 2.2 Seining Shoreline seining was used as a second collection method at each of the eleven stations described previously (Figure 1-1 and Table 2-1). Seine samples were collected on 3-4 August during the first sampling effort and on 18 August during the final survey period. Seine dimensions were 25 ft by 4 ft of 3/16-inch ace mesh, with a 4-ft by 4-ft bag of 3/16-inch ace mesh. Two seine hauls were made at each station during each sampling effort. Each haul was made in a upstream direction covering approximately 30 meters of shoreline, with the second haul being conducted upstream of the first. Seine collections were performed concurrently with electrofishing sampling, but not at the same stations during the same day. Seining was restricted to the hours commencing one-half hour after sunrise to one-half hour before sunset.2.3 Sample Processing All fish were identified to the lowest positive taxonomic level and enumerated.
For each gear type, up to 25 individuals of a species were measured for total length (umm) and weight (g) at each station. Any remaining individuals of that species were counted and weighed en masse. Minnow species (excluding carp) were counted and weighed en masse. Specimens that could not be positively identified in the field were returned to the laboratory for identification.
References used to facilitate identification included Pflieger (1975), Smith (1979), and Trautman (1981). All fish were also examined externally for evidence of disease, parasites, abnormalities, and emaciation.
A voucher collection of fish species identified during the study has been compiled and stored at Exelon Nuclear's Quad Cities Station.2.4 Water Quality Measurements Three physicochemical parameters (temperature, dissolved oxygen [DO], and pH) were measured in conjunction with the sampling program. These data were collected at each station prior to each sampling effort. Additionally, conductivity was measured prior to each electrofishing collection.
All of the physicochemical measurements were taken at mid-depth in the water column.Temperature
(°C), dissolved oxygen (ppm), and conductivity (gtmnhos) were measured using an 2-4 HDR Engineering, Inc.
YSI Model 85 handheld oxygen, conductivity, salinity, and temperature meter. A Cole-Parmer pH Tester1 was used to determine pH. All instruments were calibrated prior to each sampling event.2.5 Diversity Index Diversity indices (Shannon 1948) were computed for electrofishing and seine collections taken at each location and were compared with those calculated in previous years. Shannon-Wiener's Diversity Index was calculated for each fish species using: j=n n H,,-- ' 10_ j-n n where: Ho = the symbol for the amount of diversity in a group of S species.ni = the number of individuals of the i~h species in the sample.n = the total number of individuals in the sample.s = the total number of species in the sample.2.6 Relative Weights Condition indices are frequently used as indicators of physiological well-being.
One of the more traditional approaches to the assessment of condition uses the Fulton-type (Anderson and Gutreuter 1983) condition factor (K). As indicators of physiological well-being, condition index values should reflect proximate body composition of individual fish, e.g., lipid content, protein content, caloric content, etc. (Murphy et al. 1991). Stange and Pelton (1987) found little relationship between K and fat percentage in composite samples of forage fishes. However, strong correlations have been demonstrated between relative weight (Wr) and proximate fat content in several species (Murphy et al. 1991). Thus, W, is a reliable index of fat reserves in these species and, as such, is a useful indicator of short-term growth potential or potential for 2-5 HDR Engineering, Inc.
resistance to nutritional stress. Most Illinois State agencies, including the Illinois Department of Natural Resources (IDNR) and the Illinois Natural History Survey (INHS), currently utilize W, as the preferred measure of condition.
Development of the W, index (Wege and Anderson 1978) represents a refinement of the relative condition factor concept which allows for interpopulational comparisons by making the standard weight-length regression species-specific rather than population-specific or state-specific.
Relative weight is calculated as: W I= X 100 W., I where: W = measured weight W, = the length-specific standard weight predicted by a weight-length regressionconstructed to represent the species as a whole Length specific standard weight functions are in the form: logo W, = a + (b X log,,, total length)I where: a = the Y intercept b = the slope Murphy et al. (1991) published relative weight equations for 26 species. Equations used in this report to calculate W, (Table 2-2) are the same as those proposed in that publication.
Minimum lengths of fish for these calculations are included in this table and are necessary for most species 2-6 H:DR Engineering, Inc.

3.0 RESULTS AND DISCUSSION 3.1 Species occurrence.
Eighty-three species of fish representing 19 families have been collected from the Kankakee River and Horse Creek from 1977 through 2010 (Table 3-1). No threatened or endangered species were collected in 2010. However, river redhorse (Moxostoma carinatum), currently listed as threatened (Illinois Endangered Species Protection Board 2009), and pallid shiner (Notropis amnis), currently listed as endangered in Illinois, have been collected on an irregular basis during most years of this sampling program. Since 1990, the number of river redhorse collected (14 specimens) during these studies has declined substantially from those observed in the 1970's and 1980's (357 specimens).
Based on these data, river redhorse has become much less abundant in the Kankakee River near Braidwood Station during recent years.All but two (99.5%) of the 373 river redhorse collected since 1977 have been captured by electrofishing, while 68.7% of the 568 pallid shiners collected have been captured by minnow seine (Table 3-2).A single Petromyzontidae (lamprey) species was observed during one of the electrofishing sampling efforts in 2010. However, the fish was lost overboard before it could be identified to species. This represents the first time that an individual from this family has been collected during this long-term monitoring program. The lamprey measured approximately 150 mm (6 inches) in length. The specimen was most likely attached to fish that was dipped and brought into the boat during the 17 August electrofishing effort at Location 6R.3.2 Relative Abundance and CPE. Electrofishing and seining efforts in 2010 resulted in the capture of 3798 fish representing 43 species and 13 families (Table 3-3). Spotfin shiner was the most abundant species collected, representing 23.0% (874 individuals) of the total catch by number. Longear sunfish (16.0%), bluntnose minnow (15.7%), bullhead minnow (10.5%), largemouth bass (6.3%), and sand shiner (5.6%) were the only other species to individually comprise more than 5% of the numerical catch. Electrofishing and seining biomass was dominated by carp (29.7%), channel catfish (18.3%), smallmouth bass (8.7%), largemouth bass (6.0%), and freshwater drum (5.5%).3-1 HDR Engineering, Inc.

The catch was dominated by longear sunfish, which comprised 25.7% of all fish captured.
Bluntnose minnow (16.5%), largemouth bass (9.1%), spotfin shiner (9.1%), and bullhead minnow (7.5%), were the only other species to numerically comprise more than 5% of the total catch. Excluding gizzard shad, centrarchids dominated the catch comprising 50.4% of the electrofishing catch and were represented by nine species. Cyprinids (including carp) comprised 38.5% of the catch (seven species), catostomids 7.0% (eight species), and percids 2.1% (five species) of all fish collected.
Electrofishing biomass was dominated by carp, which constituted 30.5% of the 168.6 kg collected.
Other species that individually contributed more than 5 % of the total biomass included channel catfish (18.8%), smallmouth bass (8.9%), largemouth bass (6.0%), and freshwater drum (5.6%). Rough fish (carp and sucker species) accounted for 47.8% (80.5 kg) of the total electrofishing biomass collected.
The mean electrofishing catch-per-effort (CPE) for fish collected at all locations combined was 234.3 fish/hr (Table 3-4). This value is higher than the 33-yr average of 176.3 fish/hr (Table 3-5)and well within the range of values reported since 1977. Electrofishing CPE's since 1994 have been higher than those reported during the earlier years of these studies (1977-1993).
Electrofishing CPE has ranged from 35.2 fish/hr in 1982 to 486.3 fish/hr in 2002. In 2010, CPE by location ranged from 76.0 fish/hr at Location IR to 576.0 fish/hr at Location 3L.A total of 1689 fish representing 31 species and nine families was collected by seine in 2010.(Table 3-3). Spotfin shiner was the dominant species collected, comprising 40.4% (683 individuals) of all fish captured.
The second most abundant species taken was bluntnose minnow (14.6 %), followed by bullhead minnow (14.1%), and sand shiner (8.3 %). Total biomass of fish taken by seine was 4.5 kg. Taxa collected by minnow seine that individually comprised greater than 5% of the total catch by weight included spotfin shiner (35.9%), bluntnose minnow (11.9%), bullhead minnow (11.6%), longear sunfish (10.5%), largemouth bass 6.6%), and sand shiner (6.0%).Haul seining mean CPE for all locations combined in 2010 was 38.4 fish/seine haul. This value is lower than the 33-yr average of 58.0 fish/seine haul (Table 3-5). CPE's of fish collected by 3-8 HDR Engineering, Inc.

This is noteworthy because the extensive vegetation that has occurred throughout much of the study area during recent years (particularly 2005-2007) has had an effect on sample collections, sampling efficiency, and perhaps species utilization of these areas when compared to previous years (HDR/LMS 2006-2008 and HDR 2009). However, in 2009, 2010, and to a lesser extent 2008, the development of aquatic macrophtyes in the Kankakee River was much less than observed in 2005, 2006, and 2007. River flows in 2009 and 2010 were higher for a longer period of time in the spring and early summer than those observed during 2005-2007.
Development of aquatic macrophtyes may have been inhibited by the higher, more turbid flows that occurred in 2009 and 2010.3.3 Historical Comparison Based on sampling efforts conducted during the last three years (2007-2010), the relative abundance of spotfin shiner, bullhead minnow, bluntnose minnow, longear sunfish, and sand shiner, have remained relatively high (Table 3-6). In addition, silver redhorse, bluegill, largemouth bass, and gizzard shad abundance seems to be increasing.
Rock bass has also been commonly collected since 2008. All of the species listed in Table 3-6 are relatively common to abundant in this portion of the Kankakee River near Braidwood Station.In 2010, spotfin shiner was the most abundant species collected (Table 3-6), followed by longear sunfish, bluntnose minnow, bullhead minnow, and largemouth bass. Cyprinids accounted for four of the top 10 species collected.
Cyprinids, gizzard shad, and centrarchids (Appendix Table B- 1) have typically dominated catches of fish in the Kankakee River. The percent contribution of non-cyprinid species to the catch from 1996-2010 has generally decreased because of the large numbers of cyprinids and/or gizzard shad that have been captured.
Although not reflected in the percent contribution to the catch, the numbers of non-cyprinid species collected from 1996-2010 have generally been similar to those observed during most years.3-12 HDR Engineering, Inc.

Smallmouth bass, carp, and either golden or silver redhorse have all been substantial contributors to the total weight of fish collected (ranking from first to fifth) during the last ten years. As was the case from 2005 through 2010, channel catfish can also contribute heavily to the total biomass collected during some years. Historically, the percent composition by biomass of dominant fish species collected by electrofishing and seining has been relatively consistent during most years. Dominant taxa collected during this period include carp, gizzard shad, channel catfish, smallmouth bass, redhorse species, carpsucker species, and longear sunfish.A review of historical trends in total catch can be useful for evaluating the stability and long term productivity of a fishery. Catches of fish have exhibited considerable variability from year to year during the Braidwood Monitoring program (Table 3-5). Since 1994, the catch-per-effort of fish has been higher than most previous years. The decline in the numbers of fish collected from 1991 through 1995 was attributed to a reduction in the sampling program beginning in 1991, which decreased electrofishing effort by more than half (LMS 1996). In addition, the number of fish collected during any given year is influenced by seine collections, which can be highly variable between years. During years that produce large numbers of fish in seine collections (primarily minnows and small sunfish species), total catch is typically high. Conversely, when seine catches are low, the total number of fish collected is also generally low. Electrofishing CPE in 2010 (234.38 fish/hr) was higher than the 33-yr mean of 176.3 fish/hr. Electrofishing CPE in 2010 was within the range of values reported since 1995 and slightly higher than all of the values reported during the 1977 through 1995 sampling period. The 2010 seining CPE of 38.4 fish/haul was less than the 33-yr mean of 58.0 fish/haul.
Seining CPE's have varied markedly during the 33 years of sampling, ranging from 8.4 fish/haul in 1982 to 240.4 fish/haul in 1977.3.4 Length Frequency Distributions.
Length-frequency distributions were used to estimate age groups of four dominant species (rock bass, longear sunfish, smallmouth bass, and largemouth bass) collected from the Kankakee River.Age groups can be separated and identified as peaks in a standard length-frequency histogram; 3-14 HDR Engineering, Inc.

Eighty-nine fish measuring from 33 to 210 mm in total length are included in the length-frequency analysis of rock bass (Figure 3-1). Based on this information, at least four or five age classes of fish were collected.
Only one (1.1 %) Age 0 rock bass measuring 33 mm in TL was collected in 2010. Peaks in the length frequency histogram occurred at 70-100 mm (Age 1), 120-150 mm (Age 2), and from 160-190 mm (Age 3). The four fish larger than 200 mm were most likely Age 4 fish. Recruitment of Age 0 rock bass was weak in 2010 based on these data. In contrast, the 2007 (Age 3), 2008 (Age 2), and 2009 (Age 1) year-classes appear to be moderate to relatively strong based on data collected in 2010.The length-frequency of 421 longear sunfish measuring from 34 to 132 mm is presented in Figure 3-2. Two hundred ninety-two (69.4%) of the 421 fish that were measured ranged from 30 to 80 mm in total length (primarily Age 1), while the remaining 129 fish (30.6%) measured from 80 to 140 mm in total length. The majority of these fish were Age 2, but a few of the largest individuals may have been Age 3.Recruitment of longear sunfish appeared to be weak in 2010 based upon the relatively few Age 0 fish (<50 mm) observed in the length frequency histogram.
Similar results were noted for this species from 2005-2009 when recruitment was also reported be relatively weak based on information collected during electrofishing and seining sampling efforts. However, during 2005 (HDR/LMS 2006) and 2007 (HDR/LMS 2008) relatively large numbers (1666 and 1081 fish, respectively) of young-of-year fish measuring less than 50 mm in total length were identified only as sunfish species. Because species assignment to these very small fish is likely to contribute an unknown margin of error, only fish larger than 40 or 50 mm in total length were identified to species. Based on historical data, a large portion of these fish were longear sunfish. Longear sunfish has been the most abundant sunfish species taken during most previous years of sampling.If this assumption is correct, recruitment of this species in 2005 and 2007 would have been strong. The large contribution of Age 1 longear sunfish to the catch in 2006 and'2008 appears to validate the assumption that the majority of these unidentified Age 0 sunfish were indeed longear 3-16 HDR Engineering, Inc.

sunfish. Similar results have been noted during almost all previous years of this long-term data base. Recruitment of longear sunfish has been classified as strong to very strong during most years of these studies. This is not surprising because longear sunfish is one of the most abundant species found in this section of the Kankakee River. However, only two small young-of-year fish were classified as sunfish species in 2009 and only 16 were classified as sunfish species in 2010.However, Age I fish were the major component of the catch in 2010, which suggest that the low numbers of YOY fish captured in 2009 may have been attributed to gear bias, unfavorable sampling conditions, or some other unknown factor.The vigorous rooted aquatic plant growth that had occurred within the Kankakee River during the past few years (primarily 2005-2007) had been conducive to the survival of longear sunfish and other small fish species by affording protection from predators.
Weed growth was much less extensive in 2010, 2009, and to a lesser extent in 2008, which may explain the decline in young-of-year sunfish species captured during recent years. Reduced spawning habitat and increased predation could explain the decline of numbers collected.
In contrast, only one fish (0.2%) larger than 130 mm was collected.
Becker (1983) states that relatively few longear sunfish live to be older than Age 4. This may account for the low occurrence of longear sunfish greater than 150 mm in total length that have been collected during these studies.Fifty-four smallmouth bass were collected during 2010. Specimens ranged in length from 49 to 434 rimm (Figure 3-3). Several age classes of fish were represented in the catch, with peaks in the length frequency histogram occurring at 70 mm (Age 0), from 130 to 190 mm (Age 1), from 200 to 250 mm (Age 2), and from 260 to 320 mm (Age 3). Young-of-year smallmouth bass were strong contributors to the catch from 1994-1999, 2001-2004, and again in 2007, 2008, and 2009.However, only a relatively small portion of the smallmouth bass collected in 2000 and 2005 were Age 0 (LMS 2001 and HDR/LMS 2006). In 2006, Age 0 smallmouth bass made a moderate contribution to the total catch (HDR/LMS 2007), but the Age 0 fish that were collected were smaller than those captured during most previous years. As a result, these fish may have incurred higher mortality than would have been expected if they had been larger and in better condition to survive predation and over-wintering mortality.
In 2007, only 15 (4.5%) Age I smallmouth bass measuring from 120 to 200 mm were collected, suggesting that the recruitment and survival of the 2006 year class in this portion of the Kankakee River was indeed weak in 2006. Recruitment of 3-19 HDR Engineering, Inc.

smallmouth bass in 2010 also appeared weak based on the three fish < 100 mm TL captured by electrofishing and seining efforts in 2010.An additional grouping of smallmouth bass in the 2010 length-frequency histogram occurs from 340 to 400 mm (Age 4 or Age 5). Only two (3.7%) fish larger than 400 mm were collected in 2010. These fish were most likely Age 5 or older. Although in 2010, peaks in the length-frequency histogram of smallmouth bass > 100 mm in total length can be difficult to distinguish because of the small sample size (49 specimens), the 2005-2010 year classes (Ages 0-5) all appear to be represented in the catch.Two hundred twenty-five largemouth bass, measuring from 50 to 474 mm in total length, were collected in 2010 (Figure 3-4). Based upon the fish collected during 2010, at least four or five age classes of largemouth bass were included in the catch. One hundred seventy-two (76.4%)largemouth bass less than 100 mm in total length were captured in 2010, while 44 (19.6%) fish from 100 to 210 mm were collected.
The remaining nine fish (4.0%) ranged from 310 to 470 mm. During most years, either Age 0 and/or Age 1 largemouth bass have dominated the catch, while relatively few fish older than Age 2 have been collected.
Notable in the length frequency histogram for 2010 is the absence of any fish measuring from 210 to 310 mm. This indicates that few, if any, largemouth bass from the 2007 (Age 3) or 2008 (Age 2) year-classes were collected.
Recruitment of largemouth bass in the Kankakee River near Braidwood Station appeared to be very strong in 2010 based on the data collected by electrofishing and seining.In addition to those four species, 20 walleye measuring from 135 to 586 mm in total length were collected in 2010. Seventeen (85%) of these fish measured from 135 to 193 mm and were Age 0, while one 276 mm fish was Age 1. The last two fish measured 439 and 586 mm, respectively.
The 439 mm walleye was most likely Age 3 and the 586 mm individual was most likely Age 5.At least four age classes of walleye were included among the 20 fish captured in 2010.3-21 HDR Engineering, Inc.

3.5 COMMUNITY CHARACTERISTICS 3.5. 1 Diversity Mean diversity indices were calculated for each of the 11 individual electrofishing and seining locations in 2010. Electrofishing diversity values ranged from 2.33 at Location 5L to 3.53 at Location 5R (Table 3-8). The average diversity index for all locations in 2010 was 3. 11. This value is slightly higher than most years reported since 1977. The mean diversity index has ranged from 2.36 in 1982 to 3.74 in 2005. It should be noted that the average diversity indices were not calculated using weighted means, but are simply means of means. They should therefore be viewed with some degree of caution.Mean diversity indices for each location sampled by seining ranged from 1.44 at Location 5L to 3.23 at Location 3L (Table 3-9). Diversity indices in the Kankakee River appear to reflect habitat quality and the flow characteristics at each location during the time of collection, rather than any affect associated with the Braidwood Station intake or blowdown.
Average seining diversity indices (all locations) by year has ranged from 1.08 in 1983 to 2.97 in 2001. The average seining diversity index of 2.49 in 2010 is well within the range of values reported during the 33 years of this long-term sampling program.3.5.2 Anomalies In 2010, eight (0.21%) of the 3798 fish collected from the Kankakee River and Horse Creek exhibited some form of external anomaly (Table 3-10). Two of the eight fish were channel catfish, two were rock bass, two were freshwater drum, one was a northern hog sucker, and one was a largemouth bass. Two fish exhibited multiple anomalies.
The northern hog sucker exhibited eroded fins and lesions and one of the two rock bass with anomalies also exhibited eroded fins and lesions. In total, five species were noted to exhibit at least one type of external anomaly. During previous studies (1991-2009), fish with external anomalies have comprised from 0.1% of the fish examined in 2001 to 4.9% of the fish examined in 1993. The majority of fish during those years were afflicted with eroded fins, parasitic leeches, cysts, or anchor worm.In 2010, anchor worm (Lernaea spp.) was the only parasite observed and accounted for three 3-23 HDR Engineering, Inc.

(30.0%) of the 10 total anomalies noted. Anchor worm was noted on two of the freshwater drum and one of the rock bass taken during electrofishing sampling.DELT (Deformities, Eroded fins, Lesions, or Tumors) anomalies were noted on five (0.13 %) of the 3798 fish collected.
Lesions occurred on four individuals and eroded fins (fin rot) occurred on three individuals.
As noted in the previous paragraph, one rock bass and one northern hog sucker exhibited both eroded fins and lesions (five fish with seven total DELT anomalies).
Tumors, malformations, fish lice, leeches, cysts, and black spot were not observed on any of the fish examined in 2010. The numbers of fish noted with external anomalies by location were all low with the greatest number of fish (2) with anomalies occurring at Location 2 in Horse Creek (0.52% of all fish examined), Location 4L (0.65% of all fish examined), and Location 6L (0.45% of all fish examined).
The highest percentage of fish with anomalies occurred at Location IL where one (0.85%) of the 118 fish observed exhibited some form of external anomaly. The low percentage of individuals with DELT anomalies noted in 2010 indicates that the resident fish assemblage in this portion of the Kankakee River was in good condition (as defined by Karr, 1981) during the August sampling period.3.5.3 Relative Weight Inherent in the development of the W, equations used to calculate Wr is the objective of modeling the growth form of a species for fish in better-than-average condition.
A mean W, value close to 100 (90-110) over a range of size groups may reflect optimal health and utilization of food resources for a given population (Anderson and Gutrueter 1983). When relative weight values are considerably less than 100, problems may exist in food availability and/or feeding relationships.
A total of 215 fish (15 species) that met the minimum length criteria of the W, equations was collected (Table 3-11 and Appendix Table C-I). Of the 15 species collected, only eight were represented by more than 10 individuals.
Relative weights by species, as well as by individuals within a species, were highly variable.
Mean relative weight by species ranged from 87.2 for bigmouth buffalo to 115.1 for gizzard shad. Several factors can influence W,, including sample size, fish size, sex, food availability, competition, and spawning condition.

Twelve of the 15 species examined exhibited a W, score of greater than 90.0 and eight species (gizzard shad, river carpsucker, smailmouth buffalo, rock bass, bluegill, green sunfish, largemouth bass, and freshwater drum) scored greater than 100.3.6 Physicochemical Data Water quality data recorded in conjunction with fish sampling was measured at each location prior to every sample collection (Appendix Tables A-I to A-4). During August 2010, water temperature ranged from 24.9 °C at Location 3L on August 4 to 29.0 °C at Location 4R (the Braidwood Station discharge) on August 3. Water temperatures were slightly warmer during the second sampling period. Dissolved oxygen ranged from 5.2 to 17.0 ppm, pH from 7.9 to 8.5, and conductivity from 433 to 659 .imhos/cm.
With the exception of the relatively high dissolved oxygen readings that were recorded on August 3, the physicochemical data collected in 2010 was similar to values reported during earlier years of these studies. Each of the measured water quality parameters observed were within the range of values capable of supporting a healthy fishery.Since 1981, mean monthly discharge for the Kankakee River (Site Number 05527500) has been calculated from flow data recorded by the United States Geological Survey (USGS) near Wilmington, Illinois (Figure 3-5 and Appendix Table A-5). Based on preliminary data, the mean monthly river flows for January and June 2010 Were substantially higher than the mean monthly flows for all years combined (January 1981- August 2009). In contrast, the mean monthly river flow for September 2010 was one of the lowest reported since 1981. Mean monthly river flows for the remaining months in 2010 were all similar to or slightly less than the mean for all years combined.
These data should be viewed with caution because the current water year's data is still preliminary.
October through December 2010 preliminary mean monthly river flows were not available when this report was being prepared.3-31 HDR Engineering, Inc.

Mean monthly river flow (excluding provisional data) since 1981 has averaged 6007 cfs (Appendix Table A-5). Highest mean monthly river flows have occurred during March and April, while the lowest flows have occurred during the months of August through October. River flows in 2010 ranged from 1010 cfs in September to 16,266 cfs in January.With the exception of the August 4 sampling date, river flow during each sampling date in 2010 was similar to or below the 29-yr mean August monthly average of 2525 cfs (Appendix Table A-5). Preliminary flow data for the three sampling dates during the first sampling period on August 2, 3, and 4, were 2480, 2380, and 5650 cfs, respectively.
The increased flow observed on August 4 was the result of a strong thunderstorm that produced heavy wind and rainfall during the evening of August 3. River flows dropped quickly within a few days following this event. Flow data for the three sampling dates during the second sampling period on August 16, 17, and 18, were 1370, 1250, and 1180 cfs, respectively.
River flows were higher during the first sampling period in August 2010 when compared to the second sampling period. River flows in the Kankakee River can be highly variable over a relatively short period of time.3-33 HDR Engineering, Inc.

SUMMARY
- 1. Forty-three species of fish representing 13 families were collected from the Kankakee River and Horse Creek during the Braidwood Station Aquatic Monitoring Program in August 2010.2. No pallid shiner or river redhorse were collected during the 2010 fisheries surveys in the Kankakee River near Braidwood Station. Pallid shiner is currently listed as endangered, while the river redhorse is currently listed as threatened in Illinois.
No other protected species were observed in 2010.3. A total of 3798 fish weighing 173.1 kg was collected during electrofishing and seining efforts in 2010.4. Spotfin shiner (23.0%), longear sunfish (16.0%), blunmose minnow (15.7%), bullhead minnow (10.5%), largemouth bass (6.3%), and sand shiner (5.6%) were the most abundant species collected in 2010.5. Carp (29.7%), channel catfish (18.3%), smallmouth bass (8.7%), largemouth bass (6.0%)and freshwater drum (5.5%) comprised 68.2% of the total biomass (173.1 kg) sampled during electrofishing and seining efforts in 2010.6. Electrofishing resulted in the capture of 2109 fish representing 38 species. Longear sunfish was the most abundant species observed, accounting for 25.7% of all fish collected, followed by bluntnose minnow (16.5%), largemouth bass (9.1%), spotfin shiner (9.1%), and bullhead minnow (7.5%). Electrofishing biomass was dominated by carp, which constituted 30.5% of the 168.6 kg collected.
Carp and sucker species accounted for 47.8% of the total electrofishing biomass. Electrofishing CPE was 234.3 fish/hr in 2010, which is higher than the 33-yr average of 176.3 fish/hr.7. Thirty-one species were among the 1689 fish collected in seine samples. Spotfin shiner dominated the catch comprising (40.4%) of all fish collected, followed by bluntnose minnow (14.6%), bullhead minnow (14.1%), and sand shiner (8.3%). Seining biomass (4.5 kg) was dominated by cyprinid species with spotfin shiner comprising 35.9%, bluntnose minnow 11.9%, bullhead minnow 11.6%, longear sunfish 10.5%, largemouth bass 6.6%, and sand shiner 6.0% of the total biomass collected.
No other species individually comprised more than 5% of the total biomass collected.
Seining CPE in 2010 (38.4 fish/haul) was less than the 33-yr mean of 58.0 fish/haul.
Fewer sunfish species were collected in 2009 and 2010 than during most recent years, which may be attributed to the decline in aquatic vegetation observed throughout the entire sampling area.8. The mean diversity index of fish collected by electrofishing for all locations combined in 2010 was 3.11, which is slightly higher than most years reported since 1977. The mean diversity index for electrofishing has ranged from 2.36 in 1982 to 3.74 in 2005. The mean diversity index of fish collected by seining in 2010 was 2.49, which is well within the range of values reported since 1977. The mean seining diversity index has ranged from 1.08 in 1983 to 2.97 in 2001.4-1 HDR Engineering, Inc.
- 9. Only eight (0.21%) of the 3798 fish collected in 2010 exhibited some form of external anomaly. Lesions (40.0%), eroded fins (30.0%), and anchor worm (30.0%) accounted for all of the ten anomalies observed.
Tumors, malformations, fish lice, black spot, leeches, and cysts were not observed in 2010. Two of the eight fish afflicted were channel catfish, two were rock bass, two were freshwater drum, and one specimen each of northern hog sucker and largemouth bass was also observed with an external anomaly.The largest percentage (0.85 %) of fish collected with anomalies was observed at Location IL. The very low incidence of DELT (Deformities, Eroded fins, Lesions, and Tumors)anomalies observed in 2010, which occurred on only five (0.13%) of the 3798 fish examined, continues to indicate that the fish assemblage in this portion of the Kankakee* River is in good condition during the August sampling period.10. Mean relative weights (Wr) of fish near the Braidwood Station ranged from 87.2 for bigmouth buffalo (one individual) to 115.1 for gizzard shad. With the exception of a few individuals, fish collected in the Kankakee River during the August sampling period were in good to excellent condition.
Eight species (gizzard shad, river carpsucker, smallmouth buffalo, rock bass, green sunfish, bluegill, largemouth bass, and freshwater drum)exhibited mean relative weight scores of more than 100.11. Based on length frequency data collected by electrofishing and seining sampling efforts in 2010, recruitment of rock bass, longear sunfish, and smallmouth bass appeared to be weak in this portion of the Kankakee River, while largemouth bass recruitment appeared to be very strong.4-2 HDR Engineering, Inc.
