Assessment Comments

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

Basis for Assessment

Both uses were assessed as FST for the following reasons:  (1) BPJ of DNR Fisheries; (2) results of monitoring in 1992 show that averages of secchi depth, chl-a, total-P, and TSS were either approxiately equal to, or better than, overall averages for the 116 SPOLs sampled in 1990 and 1992; (3) according to Bachmann et al.  (1994), lake does not have problems with fishkills, has a relatively low sedimenation rate (1.0 cm/yr), and has a relatively long life expectancy (248 years).   Bachmann et al.  (1994), however, report zero swimming use for this lake.   Lake has only a slight threat from sediment delivered to the lake in ag NPS runoff.
