Basis for Assessment

SUMMARY:  The Class A (primary contact recreation) uses were "not assessed."  The Class B(LW) aquatic life uses remain assessed as "partially supported."  Fish consumption uses were "not assessed."  EXPLANATION:  The Class A (primary contact recreation) uses were "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 ("partially 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.
