Assessment Comments
Basis for Assessment
Had no violations of Class B(WW) WQC (metals not sampled). All fish contams in samples of carp (fillets and whole fish) were < 1/2 FDA action levels for dieldrin, chlordane and mercury (=FS). None of the 16 samples from mid-reservoir, and none of the 51 samples each collected at the two swimming beaches during summer seasons of 1994 and 1995, exceeded the Class A WQC of 200 organisms per 100 ml (=FS). Support of the aquatic life and swimmable uses at Saylorville Reservoir continue to be threatened by siltation from agricultural nonpoint sources.
