Monitored in 1990 by ISU for the Clean Lakes Classification study (1994).
Basis for Assessment
SUMMARY: The Class A (primary contact recreation) uses remain "not assessed." The Class B(LW) aquatic life uses remain assessed as "fully supported." Fish consumption uses remain "not assessed." EXPLANATION: The Class A (primary contact recreation) uses remain "not assessed" due to the lack of information on levels of indicator bacteria at this lake. The previous (1998) assessment of support of the Class B(LW) uses ("fully supported") was reviewed and approved by the DNR Fisheries Bureau in 2000. Fish consumption used remain "not assessed" due to lack of fish contaminant monitoring at this lake.
