Assessment Comments

Assessment is based on results of 1996 Biocriteria sampling: Fish IBI=22 (poor), BM-IBI=51 (fair).

Basis for Assessment

Used results of the October 1996 DNR biocriteria sampling near Lewis to assess support of the Class B(LR) aquatic life uses as FST due to (1) presence of a majority of the expected fish taxa (5 of 7) for streams in the Loess Hills and Rolling Prairies subecoregion and (2) lack of violations of Class B(LR) WQ criteria in the sample collected during biocriteria sampling.
