Assessment Comments

Assessment is based on results of DNR ambient monthly monitoring near St. Joseph.

Basis for Assessment

SUMMARY:  The Class B(WW) aquatic life uses were assessed as "fully supported."  Continue to assess support of fish consumption uses as "fully supported."  EXPLANATION:  Results of monitoring during the biennial period show no violations of Class B(WW) (aquatic life) water quality criteria in the 24 samples analyzed for dissolved oxygen, pH, and ammonia, and in the one sample analyzed for toxic metals; thus, the aquatic life uses were assessed as "fully supported."  Fish consumption uses remain assessed as "fully supported" based on EPA/DNR fish tissue (RAFT) monitoring near Algona in 1995 that showed levels of contaminants were less than ½ of respective FDA action levels and DNR levels of concern in composite samples of fillets from common carp and northern pike.
