Basis for Assessment
In May 1993, ACOE (Kanas City district) montiored WQ at four sites and levels of bacteria at four sites. Levels of atrazine in water ranged from 0.3 to 0.7 ppb; levels of cyanazine ranged from 0.1 to 0.6 ppb. The following levels of bacteria were reported for May 11, 1993: Buck Cr beach: 70 per 100ml; Buck Cr. Marina: 70; Southfork Marina: 300; beach at N end of dam: 4. No violations of WQ criteria for DO, pH, ammonia, Class B toxics (except Hg), or Class C toxics were reported. Thus, this information suggests that the reservoir fully support designated uses but is threatened by pesticides (Class C use), and bacteria (Class A use); Class B uses are fully supported.
