ABSTRACT Forty-three species of fish representing 12 families were collected from the Kankakee River and Horse Creek in 2012. No threatened, endangered, or unusual species were collected during either the electrofishing or seining sampling efforts in August, 2012. Electrofishing and seining resulted in the collection of 3009 fish weighing 98.4 kg. Longear sunfish (15.9%), very small unidentified sunfish species (13.1%), bullhead minnow (12.9%), bluntnose minnow (11.9%), largemouth bass (9.6%), spotfin shiner (9.2%), and blackstripe topminnow (8.2%) were the most common species collected.
Nine (0.30%) of the 3009 fish collected exhibited some form of external anomaly. Lesions (70.0%), eroded fins (20.0%), and deformities (10.0%) accounted for all of the 10 anomalies observed.
Tumors, fish lice, leeches, black spot, anchor worm, and cysts were not observed on any of the 3009 fish collected in 2012. 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 92.0 for northern pike to 123.7 for redear sunfish. With the possible exception of a very 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 was golden redhorse (six individuals), followed by rock bass, largemouth bass, and northern hog sucker (one individual each). The highest percentage of fish with anomalies occurred at Location 3R where two (0.99%) of the 202 fish examined exhibited some form of external anomaly.Spawning success and population structure were evaluated for four selected species. Recruitment for rock bass appeared to be moderately weak in 2012, while longear sunfish recruitment appeared to be moderate based on seining and electrofishing data. However, longear sunfish recruitment may have been actually strong based on the number of small individuals that were HDR Engineering, Inc.
identified only to Lepomis species. Many of these 395 very small individuals were likely longear sunfish. Smallmouth bass and largemouth bass recruitment appeared to be moderately strong and very strong, respectively.
As a point of interest, due to recent stocking efforts in the Kankakee River by the Illinois Department of Natural Resources, 34 walleye measuring from 136 to 587 mm in total length were collected during the 2012 sampling program. Twenty-seven (79.4%) of these individuals were most likely Age 0 or Age 1 fish that measured from 136 to 197 mm.Based on length frequency data, at least four age classes of walleye were included among the 34 walleye captured.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 increase in aquatic macrophytes within the study area during 2012 compared to August 2009, 2010, and 2011. The increase in aquatic vegetation during 2012 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.
Much of the increase in aquatic vegetation noted in 2012 can be attributed to the extremely low river flows that occurred throughout the Kankakee River during the entire year.iii HDR Engineering, Inc.

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 km2 (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 2012 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.

2.0 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 mm 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 8 August during the first sampling effort and on 22 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 "LU, 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 period of time ranging from one-half hour after sunrise to one-half hour before sunset.2-1 HDR Engineering, Inc.

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 9 August during the first sampling effort and on 21 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 (designated as A and B) were made at each location 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 may be performed concurrently with electrofishing sampling, but not at the same location 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 (mm) 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)i 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 (TC), dissolved oxygen (ppm), and conductivity
(.mhos) were measured using an 2-4 HDR Engineering, Inc.
YSI Model 30 handheld conductivity and temperature meter and an YSI Model 55 handheld dissolved oxygen and temperature meter. A Cole-Parmer pH Testerl 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: H. -E-' log 2 n-,-in n where: H,= the symbol for the amount of diversity in a group of S species.n, = the number of individuals of the id, 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, Wr 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: Wr = W X 100 W., where: W = measured weight W, = the length-specific standard weight predicted by a weight-length regression constructed to represent the species as a whole Length specific standard weight functions are in the form: log,,, W., = a + (b X log,, total length)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 HDR Engineering, Inc.

3.0 RESULTS
AND DISCUSSION
3.1 Species
occurrence.
Eighty-four species of fish representing 19 families have been collected from the Kankakee River and Horse Creek from 1977 through 2012 (Table 3-1). No threatened or endangered species were collected in 2012. However, river redhorse (Moxostoma carinatum), currently listed as threatened in Illinois, and pallid shiner (Notropis amnis), currently listed as endangered in Illinois (Illinois Endangered Species Protection Board 2009), have been collected on an irregular basis during most years of this sampling program. Since 1990, the number of river redhorse collected (14 specimens) 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 390 (68.4%) of the 570 pallid shiners have been captured by minnow seine (Table 3-2).3.2 Relative Abundance and CPE. Electrofishing and seining efforts in 2012 resulted in the capture of 3009 fish representing 43 species and 12 families (Table 3-3). Longear sunfish was the most abundant species collected, representing 15.9% (479 individuals) of the total catch by number. Sunfish species (13.1%), bullhead minnow (12.9%), bluntnose minnow (11.9%), largemouth bass (9.6%), spotfin shiner (9.2%), and blackstripe topminnow (8.2%) were the only other species to individually comprise more than 5 % of the numerical catch. Electrofishing and seining biomass was dominated by carp (26.2%), golden redhorse (15.1%), smallmouth bass (13.7%), channel catfish (8.9%), walleye (8.7%), largemouth bass (5.6%), and longear sunfish (5.6%).Electrofishing efforts resulted in the collection 1894 individuals representing 37 species (Table 3-3). The catch was dominated by longear sunfish, which comprised 20.6% of all fish captured.Bullhead minnow (14.4%), bluntnose minnow (11.9%), largemouth bass (10.9%), spotfin shiner (10.7%), blackstripe topminnow (5.5%), and sand shiner (5.2%) were the only other species to numerically comprise more than 5 % of the total catch. Excluding the 15 gizzard shad that were captured by electrofishing (excluded for historical comparisons), cyprinids (including carp)dominated the catch comprising 45.0% of the electrofishing catch and were represented by nine 3-1 HDR Engineering, Inc.

Centrarchids comprised 41.3 % of the catch (eight species), percids 2.8% (six species), catostomids 1.5% (six species) of all fish collected.
Electrofishing biomass was dominated by carp, which constituted 27.2% of the 94.876 kg collected.
Other species that individually contributed more than 5% of the total biomass included golden redhorse (15.6%), smallmouth bass (14.1%), channel catfish (9.2%), walleye (9.0%), longear sunfish (5.0%) and largemouth bass (5.0%). Rough fish (carp and sucker species) accounted for 48.0% of the total electrofishing biomass collected.
The mean electrofishing catch-per-effort (CPE) for fish collected at all locations combined was 210.4 fish/hr (Table 3-4). This value is higher than the 35-yr average of 178.3 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 2012, CPE by location ranged from 119.0 fish/hr at Location IR to 378.0 fish/hr atLocation 4L.A total of 1115 fish representing 27 species and ten families was collected by seine in 2012 (Table 3-3). Small sunfish (Lepomis) species that averaged one gram in weight was the dominant taxa collected, comprising 29.7% (331 individuals) of all fish captured.
The second most abundant species taken was blackstripe topminnow (12.8%), followed by bluntnose minnow (11.9%), bullhead minnow (10.3%), longear sunfish (8.0%), and largemouth bass (7.4%). Total biomass of fish taken by seine was 3.6 kg. Taxa collected by minnow seine that individually comprised greater than 5% of the total catch by weight included largemouth bass (22.3%), longear sunfish (20.9%), sunfish spp. (9.4%), bullhead minnow (8.7%), bluntnose minnow (8.5%), grass pickerel (6.4%), and spotfin shiner (5.6%).Haul seining mean CPE for all locations combined in 2012 was 25.3 fish/seine haul. This value is lower than the 35-yr average of 56.4 fish/seine haul (Table 3-5). CPE's of fish collected by minnow seine have been highly variable on an annual basis ranging from 8.4 fish/seine haul in 1982 to 240.4 fish/seine haul in 1977. Extensive beds of aquatic vegetation in the Kankakee River near Braidwood Station in 2012 made seining extremely difficult.
This contributed to the below average number of fish that were captured and influenced the species composition of the individuals that were captured.

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 2009-2011).
However, in 2009, 2010, 2011, 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 2009-2011 were higher for a longer period of time in the spring and early summer than those observed during 2005-2007.
Development of aquatic macrophtyes was inhibited by the higher, more turbid flows that occurred in 2009, 2010, and 2011. In 2012, the Kankakee River near Braidwood Station exhibited very low flows throughout the summer. As a result, the river was once again populated by extensive beds of aquatic macrophytes that surpassed the levels observed during 2005-2007.
3.3 Historical
Comparison Based on sampling efforts conducted during the last three years (2010-2012), the relative abundance of spotfin shiner, bullhead minnow, bluntnose minnow, longear sunfish, and sand shiner, have remained relatively high (Table 3-6). In addition, largemouth bass, blackstripe topminnow, brook silverside, and bluegill abundance seems to be increasing.
Longear sunfish, rock bass, and smallmouth bass have also been commonly collected throughout the course of these studies. All of the species listed in Table 3-6 are moderately common to abundant in this portion of the Kankakee River near Braidwood Station.In 2012, longear sunfish the most abundant species collected (Table 3-6), followed by bullhead minnow, bluntnose minnow, largemouth bass, and spotfin shiner. Cyprinids accounted for four of the top 10 species collected.
Cyprinid and centrarchid species (Appendix Table B-1) have dominated the catches of fish collected in the Kankakee River. The percent contribution of non-cyprinid species to the catch from 1996-2012 has generally decreased because of the large 3-12 HDR Engineering, Inc.

With the exception of blackstripe topminnow and brook silverside, the numbers of non-cyprinid species collected from 1996-2012 have generally been similar to those observed during most years.Since 1993, carp has been the dominant species collected in terms of total biomass, except in 1999 when gizzard shad ranked first, in 2004 when smallmouth bass ranked first, and in 2009 when golden redhorse ranked first (Table 3-7 and Appendix Table B-2). 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 2012, 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, buffalo species, and longear sunfish. Walleye was the third most abundant species collected in terms of biomass in 2011 and ranked fifth in 2012. In 2011, most of these fish were collected in one small area at Location 6L. River temperatures were high during the first week of sampling and most of these fish were concentrated in a very small area located directly in front of a tiled underground drainage culvert that was discharging cool water into the Kankakee River. In 2012, the 34 walleye that were collected were more evenly distributed throughout the entire sampling area.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 toyear 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 2012 (210.4 fish/hr) was higher than the 35-yr mean of 178.3 fish/hr. Electrofishing CPE in 2012 was 3-14 HDR Engineering, Inc.

The 2012 seining CPE of 25.3 fish/haul was less than half of the 35-yr mean of 56.4 fish/haul.
Seining CPE's have varied markedly during the 35 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; however, small sample size, differential growth between sexes of the same species, and/or the lack of well-defined breaks in length categories of older fish, hampers accurate interpretation of older age-classes.
Gizzard shad have been included in the length-frequency histograms during years in which adequate numbers of individuals have been collected.
However, only 17 fish of this species were collected in 2012. Therefore, a length-frequency histogram was not developed for this species during 2012. All of the gizzard shad collected during the current study were either young-of-year or Age I fish ranging from 61 to 157 mm in total length (Smith, 1979).Forty-five fish measuring from 30 to 220 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.
Twenty-seven (60.0%) Age 0 rock bass measuring from 30 to 66 mm in TL were collected in 2012. A second grouping of eight (17.8%) Age I fish ranging from 80 to 110 mm, a third grouping of seven (15.6%) Age 3 fish ranging from 150 to 180 mm, and three additional fish larger than 190 mm were also collected.
The three fish larger than 190 mm in total length were most likely Age 4 fish. Based on the length-frequency histogram, Age 2 rock bass may not have been collected during the 2012 August sampling period. Recruitment for this species in 2012 appeared to be moderate based on these data.The length-frequency of 444 longear sunfish measuring from 22 to 157 mm is presented in Figure 3-2. Sixty of these fish measured from 20 to 60 mm (13.5%) and were most likely Age 0 fish. A 3-16 HDR Engineering, Inc.

few of the larger individuals could have possibly been small Age 1 fish. Three hundred sixty-six (82.4%) of the 444 fish that were measured ranged from 60 to 110 mm in total length (primarily Age 1 and Age 2), while only 17 fish (3.8%) greater than or equal to 110 mrn in total length were collected.
The majority of these fish were most likely Age 3, but a few of the smaller individuals may have been Age 2, while the largest individuals could possibly have been Age 4.Recruitment of longear sunfish appeared to be moderately weak in 2012 based upon the number of Age 0 fish (< 60 mrm) observed in the length frequency histogram.
Similar results were noted for this species from 2005-2011 when recruitment was also reported be relatively weak based on information collected during electrofishing and seining sampling efforts. However, during 2005 (HDRILMS 2006) and 2007 (HDRILMS 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 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 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, only 16 were classified as sunfish species in 2010 and only five were classified as sunfish species in 2011. However, Age 1 fish were a major component of the catch in 2010 and 2011, which suggest that the low numbers of YOY fish captured in 2009 and 2010 may have been attributed to gear bias, unfavorable sampling conditions, or some other unknown factor. In 2012, 395 (13.1%) of 3009 fish collected by electrofishing and minnow seine were identified as Leponis spp. Most likely, a large percentage of these fish were longear sunfish.3-19 HDR Engineering, Inc.
The vigorous rooted aquatic vegetation that occurred within the Kankakee River from 2005-2007 and again in 2012 was conducive to the survival of longear sunfish and other forage species because it provided increased areas of refuge from predation.
Weed growth was much less extensive during 2008 through 2011, which may explain the decline in young-of-year sunfish species captured during recent years. Only three fish (0.7%) larger than 130 mm were collected in 2011 and 2012. 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-five smallmouth bass were collected during 2012. Specimens ranged in length from 56 to 462 mm (Figure 3-3). Several age classes of fish were represented in the catch, with peaks in the length frequency histogram occurring at 80 nmm (Age 0), from 140 to 200 mm (Age 1), and at 390 nmm (Age 4). Nine Age 2 or Age 3 fish were collected that ranged in length from 270 to 380 mm in total length. 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 small portion of the smallmouth bass collected in 2000, 2005, and 2010 were Age 0 (LMS 2001 and HDR/LMS 2006, HDR 2011). 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 1 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 smallmouth bass in 2011 appeared to be moderately strong based upon the 20 (35.7%) fish that were collected and measured from 40 to 80 mm in total length. Similar results were observed in 2012 when 26 (47.3%) of the 55 fish measured less than 110 mm.Three (5.5%) fish larger than 400 mm were collected in 2012. The largest of the three fish measured 462 mm in total length and was most likely Age 5 or older. Although in 2012, peaks in the length-frequency histogram of smallmouth bass > 110 mm in total length is difficult to distinguish because of the small sample size (29 specimens), the 2007-2012 year classes all appear to be represented in the catch.3-20 HDR Engineering, Inc.

Two hundred eighty-nine largemouth bass, measuring from 64 to 282 mm in total length, were collected in 2012 (Figure 3-4). Based upon the fish collected during 2012, at least four age classes of largemouth bass were included in the catch. Two hundred and sixty-nine (93.1 %)largemouth bass less than 130 mm in total length were captured in 2012, while 19 (6.6%) fish from 150 to 250 mm were collected.
The remaining individual measured 282 mm. During most years, either Age 0 and/or Age 1 largemouth bass have dominated the catch, while few fish older than Age 2 have been collected.
Notable in the length frequency histogram for 2010 and 2012 is the absence of any fish measuring greater then 300 mm. This indicates that few, if any, largemouth bass from the 2007 (Age 5), 2008 (Age 4), or 2009 (Age 3) year-classes were collected.
Recruitment of largemouth bass in the Kankakee River near Braidwood Station appeared to be strong in 2011 and 2012 based on the data collected by electrofishing and seining.In addition to those five species, 34 walleye measuring from 136 to 587 mm in total length were collected in 2012. Twenty-seven (79.4%) of these fish measured from 136 to 197 mm and were either Age 0 or Age 1 fish, while one fish measured 368 mm and was most likely either Age 2 or Age 3. Four fish (11.8%) measured from 411 to 481 mm (Age 3 or Age 4), while the remaining two individuals were likely either Age 4 or Age 5 fish that measured 569 and 587 mm, respectively.
Based on the data collected during, at least four age classes of walleye were included among the 34 fish captured in 2012.3.5 COMMUNITY CHARACTERISTICS
3.5.1 Diversity
Mean diversity indices were calculated for each of the 11 individual electrofishing and seining locations in 2012. Electrofishing diversity values ranged from 2.62 at Location 3L to 3.83 at Location 5R (Table 3-8). The average diversity index for all locations in 2012 was 3.24. This value is 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.3-22 HDR Engineering, Inc.

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 2.77 in 2012 was the sixth highest reported since 1977 and well within the range of values reported during the 35 years of this long-term sampling program.3.5.2 Anomalies In 2012, nine (0.30%) of the 3009 fish collected from the Kankakee River and Horse Creek exhibited some form of external anomaly (Table 3-10). In total, four species were noted to exhibit at least one type of external anomaly. Six of the 9 fish were golden redhorse, while the remaining three individuals included a largemouth bass, a rock bass, and a northern hog sucker.One of the six golden redhorse exhibited lesions and eroded fins. During previous studies (1991-2011), 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. Parasites, including leeches, black spot, anchor worm, fish lice, and cysts, were not noted on any of the fish examined in 2011 or 2012.DELT (D2eformities, Eroded fins, Lesions, or Tumors) anomalies were noted on all nine of the fish with external anomalies.
Lesions occurred on seven individuals, eroded fins occurred on two individuals, and a malformation (crooked spine) occurred on one individual.
Tumors were not observed on any of the fish examined in 2012. The number of fish observed with external anomalies by location were all relatively low. The greatest number of fish with anomalies by sampling area occurred at Location 3L where two (0.99%) of the 202 fish examined exhibited some form of DELT anomaly. No anomalies were noted at five of the 11 sampling locations examined during August 2012 (Table 3-10). The low incidence of individuals with DELT anomalies noted in 2012 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.3-26 HDR Engineering, Inc.

3.5.3 Relative
Weight Inherent in the development of the W, equations used to calculate W, 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 112 fish (12 species) that met the minimum length criteria of the Wr equations was collected (Table 3-11 and Appendix Table C-i). Of the 12 species collected, only four 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 92.0 for northern pick to 123.7 for redear sunfish. Several factors can influence W,, including sample size, fish size, sex, food availability, competition, and spawning condition.
Each of the 12 species examined appeared to reflect optimal health and utilization of food resources based upon the relative weights of fish that were collected during the August 2012 Braidwood Fish Monitoring Program. Five of the 12 species examined exhibited a W, score from 92.0 to 98.6, while the remaining seven species all exhibited a W, score of greater than 100.0 (rock bass, bluegill, green sunfish, redear sunfish, smallmouth bass, largemouth bass, and freshwater drum).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 2012, water temperature ranged from 23.3 °C at Location 3L on August 22 to 29.5 *C at Location 5L on August 8. Water temperatures were warmer during the first sampling period due to an extended period of unusually warm air temperatures in July and early August. Dissolved oxygen levels were also slightly higher during the second sampling period and ranged from 9.8 to 11.5 ppm, pH from 7.6 to 8.4, and conductivity from 593 to 744 JnLmhos/cm.
The physicochemical data collected in 2012 was similar to values reported during previous years of these studies. Each of 3-30 HDR Engineering, Inc.

Based on preliminary data, the mean monthly river flows for January through October 2012 were all substantially below the mean monthly flows for all years combined (January 1981- September 2012). In fact, river flows in April 2012 were the lowest reported since 1981. These data are preliminary, but the river flows in the Kankakee River were obviously well below average during the first nine months of the year. October through December 2012 preliminary river flows were not available at the time this report was prepared.Mean annual river flow in the Kankakee River near Braidwood Station from 1981 through 2011 has ranged from 3095 cfs in 2000 to 11,570 cfs in 1993. The mean annual river flows since 1981 (excluding 2012 data) has averaged 6031 cfs (Appendix Table A-5). Highest mean monthly river flows have generally occurred in March and April, while the lowest flows have occurred during the months of August through October. River flows in 2012 ranged from 700 cfs in July to 6985 cfs in May. River flows in the Kankakee River during 2012 can be characterized as being extremely low throughout the first nine months of the year.River flows during the first sampling period on August 8 (703 cfs) and August 9 (775 cfs) were substantially below the 32-yr mean of 2431 cfs (Appendix Table A-5). During the second sampling period on August 21 (775 cfs) and August 22 (775 cfs) flows were similar to those observed during the first week of sampling when the flows were extremely low. River flows were the highest during the first few days of August and continued to decline throughout the remainder of the month. River flows in the Kankakee River can be highly variable over a relatively short period of time.3-32 H-DR Engineering, Inc.

SUMMARY
- 1. Forty-three species of fish representing 12 families were collected from the Kankakee River and Horse Creek during the Braidwood Station Aquatic Monitoring Program in August 2012. Sampling was hindered by the excessive growth of rooted and floating aquatic plants that were fostered by low flows and warm temperatures.
- 2. No threatened or endangered species were collected during the 2012 fisheries surveys in the Kankakee River near Braidwood Station. Neither pallid shiner nor river redhorse were collected in 2012. Pallid shiner is currently listed as endangered, while the river redhorse is currently listed as threatened in Illinois.
Both of these species have been collected during several of the previous years of these studies.3. A total of 3009 fish weighing 98.4 kg was collected during electrofishing and seining efforts in 2012.4. Longear sunfish (15.9%), sunfish spp. (13.1%), bullhead minnow (12.9%), bluntnose minnow (11.9%), largemouth bass (9.6%), spotfin shiner (9.2%), and blackstripe topminnow (8.2%) were the most abundant species collected in 2012.5. Carp (26.2%), golden redhorse (15.1%), smallmouth bass (13.7%), channel catfish (8.9%), walleye (8.7%), largemouth bass (5.0%), and longear sunfish (5.0%) comprised 82.6 % of the total biomass (98.4 kg) collected during electrofishing and seining efforts in 2012.6. Electrofishing captured 1894 fish representing 37 species. Longear sunfish was the most abundant species observed, accounting for 20.6% of all fish collected, followed by bullhead minnow (14.4%), bluntnose minnow (11.9%), largemouth bass (10.9%), spotfin shiner (10.7%), blackstripe topminnow (5.5%), and sand shiner (5.2%). Electrofishing biomass was dominated by carp, which constituted 27.2% of the 94.9 kg collected.
Carp and sucker species accounted for 48.0% of the total electrofishing biomass.Electrofishing CPE was 210.4 fish/hr in 2012, which is higher than the 35-yr average of 178.3 fish/hr.7. Twenty-seven species were among the 1115 fish collected in seine samples. Small unidentified sunfish species that average approximately one gram dominated the catch comprising (29.7%) of all fish collected, followed by blackstripe topininnow (12.8%), bluntnose minnow (11.9%), bullhead minnow (10.3%), longear sunfish (8.0%), and largemouth bass (7.4%). Seining biomass (3.6 kg) was dominated by largemouth bass (22.3%), longear sunfish (20.9%), and unidentified sunfish spp. (9.4%), bullhead minnow (8.7%), bluntnose minnow (8.5%), grass pickerel (6.4%), and spotfin shiner (5.6%). No other species individually comprised more than 5% of the total biomass collected.
Seining CPE in 2012 (25.3 fish/haul) was less than the 35-yr mean of 56.4 fish/haul.

- 8. The mean diversity index of fish collected by electrofishing for all locations combined in 2011 was 3.24, 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 2012 was 2.77, which is the sixth highest reported since 1977. The mean seining diversity index has ranged from 1.08 in 1983 to 2.97 in 2001.9. Only nine (0.30%) of the 3009 fish collected in 2012 exhibited some form of external anomaly. Lesions (70.0%), eroded fins (20.0%), and deformities (10.0%) accounted for all of the 10 anomalies observed.
Tumors, fish lice, black spot, leeches, anchor worm, and cysts were not observed in 2012. One of the nine fish afflicted with anomalies exhibited two anomalies.
Six of the nine fish with anomalies were golden redhorse, while the remaining three individuals included a largemouth bass, a rock bass, and a northern hog sucker. The largest percentage (0.99%) of fish collected with anomalies was observed at Location 3L. No anomalies were observed at five of the 11 sampling locations examined.
The very low incidence of DELT (Deformities, Eroded fins, Lesions, and Tumors) anomalies observed in 2012, 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 92.0 for northern pike (one individual) to 123.7 for redear sunfish (one individual).
With the exception of a few individuals, fish collected in the Kankakee River during the August sampling period were in good to excellent condition.
Seven species (rock bass, bluegill, green sunfish, redear sunfish, smallmouth bass, 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 recruitment of rock bass was moderately weak and longear sunfish recruitment appeared to be moderate in this portion of the Kankakee River during August 2012. Smallmouth bass recruitmient appeared to moderately strong and largemouth bass recruitment was strong based on these same data. Recruitment analysis of longear sunfish based on data collected during the course of these studies can be unreliable because of the number of very small young-of-year sunfish that may be identified only as Lepomis species. Three hundred ninety-five individuals that weighed approximately one gram were identified as only Lepomis species in 2012. A large percentage of these fish were most likely longear sunfish.4-2 HDR Engineering, Inc.
