Documentation

Assessment Comments

Assessment is based on results of (1) ISU lake survey in 1992, (2) surveys by IDNR Fisheries Bureau (3) ISU report on lake phytoplankton communities, and (4) results of U.S. EPA/IDNR fish tissue monitoring in 1995.

Basis for Assessment

Used assessments of support of the Class A (primary contact) uses (=FST) and the Class B(LW) aquatic life uses (=FST) developed for the 1994 report. Used results of fish contaminant monitoring conducted for the 1995 DNR/EPA Regional Ambient Fish Tissue (RAFT) monitoring program to assess support of the fish consumption uses as "fully supported" (FS) due to levels of all contaminants less than 1/2 FDA action levels in the composite samples of channel catfish and largemouth bass fillets analyzed.
