Assessment Comments
Monitored in 1992 by ISU for Clean Lakes Classification study (1994). Monitored for 1994 RAFT (008723, 1117MBR).
Basis for Assessment
Used assessments of support of the Class A (primary contact) uses (=NAS) and Class B(LW) aquatic life uses (=PS) developed for the 1994 report; no more recent information available for assessing these uses. Used results of fish contaminant monitoring conducted for the 1994 Regional Ambient Fish Tissue (RAFT) monitoring program to assess support of the fish consumption uses as FS due to all contaminants less than 1/2 of FDA action levels in the composite sample of largemouth bass fillets analyzed; no contaminants exceeded DNR levels of concern (see report of 1994 RAFT program in Iowa (DNR 1996)).
