Assessment Comments

Monitored in 1992 by ISU as part of Clean Lakes Classification study (1994).

Basis for Assessment

Assessment was changed to FST [both fishable & swimmable uses] for the following reasons:  (1) BPJ of DNR Fisheries; (2) results of monitoring in 1992 show that overall averages for secchi depth, total-P, chl-a, and TSS were better than overall averages from the 116 SPOLs sampled in 1990 and 1992 +/- 1 SD; (3) lake has low fish kill frequency ("infrequent") (Bachmann et al.  1994).  Thus lake has better than average water quality for swimming and has physical characteristics to prevent fishkills.   Bachmann et al.  (1994) show that no swimming use occurs at this lake.
