Assessment Comments

Assessment is based on results of DNR/UHL biocriteria sampling on July 22, 1996: Fish-IBI=57 (good); BM-IBI=80 (excellent).

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 FS due to (1) exceptionally diverse fish community (21 spp., 5 fams) with nearly all (10 of 11) regionally expected fish taxa present and (2) no violations of Class B(LR) WQ criteria in the sample collected during biocriteria sampling.
