Assessment Comments

Basis for Assessment

SUMMARY:  The previous assessment of support of the Class A (primary contact recreation) uses was changed from "fully supporting" to "not assessed."  Continue to assess support of both the Class B(LW) aquatic life uses and fish consumption uses as "fully supported."  EXPLANATION:  The level of support of the Class A primary contact uses was changed from "fully supporting" to "not assessed" due to lack of information on indicator bacteria for this lake.   The Class B(LW) aquatic life uses were assessed as "fully supporting" based on the review of the previous (1998) assessment in 2000 by the DNR Fisheries Bureau.   Fish consumption uses were assessed as "fully supporting" based on EPA/DNR fish tissue (RAFT) monitoring in 1994 that showed that levels of contaminants in composite samples of fillets from channel catfish and largemouth bass were less than one-half of the respective FDA action levels and DNR levels of concern.
