Monitored in 1990 and 1992 by ISU for the Clean Lakes Classification Study (1994).

Basis for Assessment

Fishable uses were assessed as FST & swimmable uses were not assessed for the following reasons: (1) BPJ of DNR Fisheries; (2) results of monitoring show that average levels of total-P and TSS are better than overall averages for the 86 SPO impoundments sampled in 1990 and 1992; average level of secchi depth is slightly worse than the overall average; the average level of chl-a, however, is worse than the overall average + 1 SD and is one of the highest chl-a averages for the SPO impoundments sampled in 1990 & 92; (3) lake does not have problems with fishkills; (4) lake has a moderately high sed rate (3.2 cm/yr) but a relatively long life expectancy (90 years) for a small impoundment; (5) lake supports moderate amount of fishing. Although designated for swimmable uses, lake does not have a swimming beach and Bachamann et al. report swimming use as zero; thus, swimming use not assessed.
