Basis for Assessment

Fishable uses were assessed as FST and swimmable uses were "not assessed" for the following reasons: (1) results of monitoring show that average levels of total-P, TSS, and chl-a are approximately equal to overall averages for the 116 SPOLs sampled in 1990 and 1992; average secchi depth, however, was worse than the overall average; (2) lake does not have problems with fishkills; (3) lake has a relatively low sedimentation rate (2.1 cm/yr) and relatively long life expectancy (140 years) for an impoundment; (4) although designated for swimmable uses, lake does not have a swimming beach and swimming use was reported as zero in Bachmann et al. (1994). Thus, lake has approximately average WQ for Iowa SPOLs; low transparency probably not a problem for fishable uses. No problems with toxics in sediment, water, or fish tissue in 1990.
