Basis for Assessment

Continued to use the assessments of support of the Class A primary contact uses (=FST) and Class B(LW) aquatic life uses (=FST) developed for the 1994 report.   DNR Fisheries biologists have identfied aquatic plants (macrophytes) as serious threat to the continued support of the Class A and Class B(LW) uses.
