Assessment Comments

Assessment is based on results of surveys by IDNR Fisheries Bureau.

Basis for Assessment

The assessment of support 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 "not assessed" due to lack of swimming uses at this lake (no beach area), and the Class B(LW) aquatic life uses remain assessed as FST.
