Assessment Comments
Monitored in 1990 by ISU for the Clean Lakes Classification study (1994).
Basis for Assessment
Fishable use assessed as FS and swimmable uses were not assessed for the following reasons: (1) BPJ of DNR Fisheries; (2) average levels of secchi depth, total-P, and sedimentation rate are in the best 10 percent of the 86 SPO impoundments sampled in 1990 and 1992; averages of chl-a, TSS, and years-to-fill also much better than overall averages for the 86 SPOLs; (3) lake does not have problem with fishkills. Lake does not have a swimming beach, and Bachmann et al. report swimming use as zero; thus, use not assessed.
