Basis for Assessment
Had no violations of Class B(WW) WQC (metals not sampled). All fish contams in fillet samples < 1/2 FDA levels; however, levels of dieldrin in WF samples in 91=293 & 287 ppb; thus assess fish consumption uses as FST. Only 2 of 92 samples contained fecal coliforms > Class A WQC. When combined w/ BPJ of DNR field staff, reservoir was assessed as FST.
