Assessment Comments
Monitored in 1990 by ISU as part of the Clean Lakes Classification study (1994).
Basis for Assessment
Assessed as FS (swimmable) and FST (fishable) for the following reasons: (1) BPJ of DNR Fisheries, (2) average levels of secchi depth, total-P, chl-a, and TSS are all better than overall averages for the 116 SPOLs sampled in 1990 and 1992; all parameters are within the overall means +/- 1 SD but TSS and secchi depth tend toward the better end of this range; (3) lake does not have problems with fishkills; (4) lake has relatively low sedimentation rate (0.4 cm/yr) (Bachmann et al. 1994).
