Basis for Assessment
No violations of WQC for Class B; thus assess as FST due to known threats from ag. NPS. Of the 6 samples analyzed for fecal coliforms, 4 were collected at approx. average flows; 3 of these samples had levels of fecals > Class A WQC; due to lack of complete data, use BPJ to assess as PS. Not sure of source of these rel. high levels of fecals; thus, used traditional sources of agricultural NPS and municipal WWT.
