Assessment Comments

Assessment is based on results of 1996 biocriteria sampling: Fish IBI = 55 (good) 14 species, 4 families, BM-IBI = 53 (fair).

Basis for Assessment

Used results of the July 1996 DNR stream biocriteria sampling to assess support of the Class B(LR) aquatic life uses as FST due to (1) nearly all expected fish taxa present and (7 of 9) & (2) no violations of Class B(LR) WQ criteria in the sample collected during biocriteria sampling.   Site was sampled as a reference site for the 47a subregion.
