Basis for Assessment

SUMMARY:  The Class A (primary contact recreation) uses remain "not assessed."  The Class B(LW) aquatic life uses remain assessed as "partially supported."  The Class C (drinking water) uses remain assessed as "fully supported / threatened."  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 assessment of support of the Class B(LW) uses was reviewed and approved by the DNR Fisheries Bureau in 2000.   The assessment of support of the Class C (drinking water) uses remains based on the UHL survey of water supply reservoirs in 1995 (Miller and Kennedy 1995) (see assessment developed for the 1996 report above).   Fish consumption used remain "not assessed" due to lack of fish contaminant monitoring at this lake.
