Monitored in 1990 by ISU as part of the Clean Lakes Classification Study (1994) an used results of fish contaminant monitoring conducted in August 1994 for the Regional Ambient Fish Tissue (RAFT) monitoring program.

Basis for Assessment

Ued assessments of support developed for the 1994 report for Class A (primary contact) uses (=FST) and for the Class B(LW) aquatic life uses (=FST).   Used results of fish contaminant monitoring conducted in August 1994 for the Regional Ambient Fish Tissue (RAFT) monitoring program to assess support of the fish consumption uses as FS due to all contaminants at levels less than 1/2 the FDA action levels in the composite samples of fillets from carp and from walleyes.
