Basis for Assessment
DW uses were assessed as NS, fishable uses were assessed as PS, and swimmable uses were not assessed for the following reasons: (1) levels of atrazine exceeded MCL from June through Sept 1991 and the yearly average approx = 7 ug/l (=NS); (2) avg levels of secchi depth, total-P, and TSS during the May-Aug period were worse than overall averages for SPO impoundments sampled during 1990 and 92; averages for secchi depth and TSS were in the worst 10% of the SPO impoundments; (3) although designated for swim. uses, lake does not have a swimming beach; thus presume level of swimming use is zero. In Feb 93, atrazine, cyanazine, & metolachlor at low levels (Miller and Kennedy 1993).
