Assessment Comments
Assessment is based on results of surveys by IDNR Fisheries Bureau.
Basis for Assessment
The assessments developed for the 1994 and 1996 reports were reviewed and approved by the DNR Fisheries Bureau. Thus, the Class A (primary contact recreation) uses remain assessed as PS primarily due to nuisance blooms of algae, and the Class B(LW) aquatic life uses remain assessed as PS due to high levels of nutrients and due to populations of carp that contribute to turbidity and resuspension of nutrients. Due to these continuing water quality problems, this lake was placed on the list of Section 303(d) waters at the recommendation of the DNR Fisheries and Water Quality bureaus.
