Primary impairment is the natural shallowness (max d= 6' mean d=5') that allo ws resuspension of sediment and nutrients that lead to problems with organic e nrichment and problems with either rooted or planktonic aquatic vegetation.

Thus, these data suggest that the lake has slightly poorer water q uality than average for SPOLs in Iowa; (3) results of RAFT monitoring in 19 93 show no contaminants at levels of concern. Past assessments have suggested that WQ is impacted by urban runoff from the city of Clear Lake. Levels of use for fishing and swimming are relatively high for natural SPOLs in Iowa. Lakethreatened by urban runoff and instability of water level. For 1996 re port, used assessments of support of the Class A (primary contact) uses (=F ST), the Class B(LW) aquatic life uses (=FST), and the fish consumption use s (=FS) developed for the 1994 report. For th e 1998 report, assessed support of the Class A primary contact recreation us es as FST due to excessive growth of phytoplankton resulting from excess nutrients (primarily phosphorus) in the lake. Hypothesized sources of e xcess nutrients include runoff from urban areas, agricultural runoff, n aturally high soil fertility, effects of carp and other bottom bottom feeding f ish, and nutrient export from nearby wetlands. During the reporting period, bl ooms of algae have been recognized as detracting from the aesthetic ap peal of the lake for swimming, water skiing, and other Class A-type uses. A recent WQ evaluation by Wisconsin limnologist Paul Garrison suggests th at, in terms of nutrient levels and levels of algae, lake water quality has bee n declining since the 1940s with even more rapid decline over the last five yea rs. Several efforts are underway to address this problem, including the Clea r Lake Enhancement And Restoration Project (CLEAR) and year-long WQ study proposed by limnologists at Iowa State University to identify specific sou rces of nutrients and recommend actions to correct WQ problems. Class B(LW) aq uatic life uses were assessedas FS: the DNR Fisheries Bureau reports that Clear Lake has supported above average fish populations over the last few y ears. The March/April 1998 Iowa Conservationist reports that Clear Lake provi des good to excellent angling opportunities for walleye, muskellunge, and c hannel catfish. The Class C drinking water uses designated for the lake we re not assessed: no data or other information are available for developing an assessment of these uses.

Thus, water quality of this lake appears to be impacted by sediment and nutrients primarily from agriculture. (3) Lake has relatively high s edimentation rage (9.1 cm/yr) and a relatively short estimated life (29 years). According to Bachmann et al. (1994), lake supports considerable swimming, but these uses may be impaired by suspended sediment or phytoplankton-related turbidity. For 1996 report, used assessments of support of the Class A (primary co ntact) uses (=PS) and the Class B(WW) aquatic life uses (=PS) developed for t he 1994 report. Information from 1994 DNR Iowa Water Quality Project fact sheet supports this assessment: "sediment, nutrients, pesticides, and anima l wastes from the 18,966-acre watershed are threatening the quality of this w idely-used lake. . .During the last 24 years, the lake has lost 25 acres of surface area because of sedimentation." The current water quality project ha s goals of reducing sedimentation of Beeds Lake by 70% and implementati on of agricultural BMPs in the watershed. For the 1998 rep ort, used results of fish tissue monitoring for the 1996 Region Ambient Fish Ti ssue (RAFT) monitoring program to assess support of fish consumption uses as FS: levels of all contaminants in the composite fillet samples of both largemou th bass and channel catfish were below 1/2 of the respective FDA action leve ls. Continue to use the assessments of support of the Class A primary contac t recreation uses and the Class B(WW) aquatic life uses (both=PS) developed for the 1994 report. This assessment was reviewed by the DNR Fisheries Bureau . The DNR Fisheries biologist expects that water quality in this lake will i mprove due to recent Section 319 nonpoint source control projects.

Levels of chlordane that exceede d FDA action level for chlordane led to a fish consumption advisory for all s pecies in March 1986. Levels of PCBs first exceeded the FDA action level in the 1988 RAFT sample. Levels of chlordane and PCBs remained above FDA action levels until the 1994 sample, when levels of both chlordane and PCBs were be low FDA action levels (chlordane: 0.28 mg/kg; total PCBs: 0.29 mg/kg) in a composite sample of carp fillets. Addtional years of monitoring will be nec essary to determine whether contaminant levels have dropped and whether the co nsumption advisory can be modified. The fish consumption advisory issued in M arch 1986 remains in effect; thus, the assessment of support of the fish cons umption uses = NS. For the 1998 report, continued to assess support of fish consumption uses as NS due to contin ued existence of the fish consumption advisory issued in March 1986. Samplin g for the 1996 Regional Ambient Fish Tissue (RAFT) monitoring program s howed that (1) levels of all contaminants in the composite sample of largem outh bass fillets were very low and well below 1/2 of the respective FDA actio n levels and (2) levels of technical chlordane in the composite sample of carp fillets (0.18 mg/kg wet weight (=ppm)) exceeded 1/2 the FDA action le vel of (0.300 ppm) while the level of total PCBs (0.295 ppm) was less than 1 /2 the FDA action level of 2.0 ppm.
