Basis for Assessment

SUMMARY: The Class A (primary contact recreation) uses and the Class B(LW) aquatic life uses remained assessed as "partially supported." Fish consumption uses were asessed as "fully supported." EXPLANATION: The Class A uses remained assessed as "partially supported" based on information from the DNR Fisheries Bureau that heavy blooms of bluegreen algae have occurred in recent years at this lake. The Class B(LW) aquatic life uses remain assessed as "partially supported" based on review and approval of the previous (1998) assessment by the DNR Fisheries Bureau in 2000. The water quality trend for this lake remains "stable." Fish consumption uses were assessed as "fully supported." EPA/DNR fish tissue (RAFT) monitoring conducted in 1998 showed that levels of contaminants in the composite sample of fillets from channel catfish and largemouth bass were less than ½ of the respective FDA action levels and DNR levels of concern for organochlorine contaminants and mercury. Thus, fish consumption uses were assessed as "fully supported."
