Assessment Comments
Assessment is based on results of (1) ISU Clean Lakes Classification study in 1990 and (2) surveys by IDNR Fisheries Bureau.
Basis for Assessment
The assessments devloped for the 1994 and 1996 reports were reviewed and approved by the DNR Fisheries Bureau. Thus, the Class A (primary contact recreation) uses remain "not assessed" due to lack of swimming at this lake, and the Class B(LW) uses remain assessed as PS due to siltation from agricultural nonpoint sources. At the recommendation of the DNR Fisheries Bureau, this lake was placed on the 1998 list of Section 303(d) waters.
