Assessment Comments

Monitored by ISU in 1990 for Clean Lakes Classification Study.

Basis for Assessment

Fishable uses were assessed as PS, and swimmable uses were not assessed for the following reasons:  (1) BPJ of DNR staff; (2) average levels of secchi depth and chl-a are slightly worse than the overall averages for the 86 SPO impoundments sampled in 1990 and 1992; average levels of total-P and TSS are approx equal to, or better than, the overall averages; (3) lake has only minor problems with fishkills; (4) according to Bachmann et al., lake supports relatively low amount of fishing and is not used for swimming (lake does not have a swimming beach); (5) lake has an extremely high sedimentation rate and short life expectancy (15 years).   Thus, although lake has approxiately average WQ, high sedimentation rate & low level of fishing use (in lowest 10% of SPO impoundments) suggest that the aquatic life uses are only partially supported.
