Assessment Comments

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

Basis for Assessment

Both fishable and swimmable uses were assessed as FST for the following reasons: (1) monitoring conducted in 1992 shows that average levels of secchi depth, total-P, chl-a, and TSS were approxmimately equal to, or better than, overall means for the 116 SPOLs sampled in 1990 and 1992; (2) according to Bachmann et al. (1994), the lake supports relatively high amounts of fishing and swimming; (4) lake does not have a fishkill problem; (5) lake has a moderately high sedimentation rate (3.1 cm/yr) and has a moderately short life expectancy (77 years). Thus, lake appears to support both fishable and swimmable uses, but uses are threatened by sedimentation from agricultural areas. Lake is identified in March/April "Iowa Conservationist" (Fishing Forecast) as providing good catches of channel catfish and largemouth bass.
