Basis for Assessment

SUMMARY:  The Class A (primary contact recreation uses) were "not assessed."  Continued to assess support of the Class B(LW) aquatic life uses as "fully supported."  Fish consumption uses remain "fully supported."  EXPLANATION:  The Class A (primary contact recreation) uses were changed from "fully supported" to "not assessed" due to the lack of information on levels of indicator bacteria at this lake.   This change reflects a change in DNR's Section 305(b) assessment methodology and does not suggest any change in lake water quality.   The previous (1998) assessment of support of the Class B(LW) uses ("fully supported / threatened") was reviewed and approved by the DNR Fisheries Bureau in 2000.   Fish consumption uses remain "fully supported" based on results of EPA/DNR fish contaminant (RAFT) monitoring in August 1997 (see assessment developed for the 1998 report above).
