Assessment Comments
Basis for Assessment
Had no viols of Class B(WW) WQC (no metals)(FS). No viols of fecals at lake station; only 2 of 84 samples at beaches in 1992-93 exceeded Class A WQC (=FS). No ISU fillet samples w/ contams > 1/2 FDA action levels; fish consumpt advis lifted in April 1993 (=FS). Reservoir, however, continues to have severe siltation problems resulting in periodic increases in normal pool elevations. Lutz (1993: 160) reports a fishkill at RR in late August 92; only CCAT killed; disease blamed.
