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 / threatened." The Class C (drinking water) uses were "not assessed." Fish consumption uses remain assessed as "fully supported." EXPLANATION: The level of support of the Class A (primary contact recreation) uses was changed from "fully supported / threatened" to "not assessed" due to the lack of information on levels of indicator bacteria at this lake. This change in assessment reflects a change in the DNR's Section 305(b) assessment methodology and does not reflect any known change in 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. The Class C (drinking water) uses remained "not assessed" due to the lack of water quality information. Fish consumption uses remained assessed as "fully supported" based on results of EPA/DNR fish tissue (RAFT) monitoring in 1996 (see assessment developed for the 1998 report above).
