Assessment Comments
1996 biocriteria: IBI=30, 10 spp; 2 fams. 1996 Biocriteria: Fish IBI= 40 (fair), BM-IBI= 62 (good).
Basis for Assessment
Used results of the September 1996 DNR biocriteria sampling near Stennett to assess support of the general uses as FST due to (1) presence of a moderately diverse fish community for Loess Hills and Rolling Prairies subecoregion (10 spp., 2 fams), (2) presence of a majority of the regionally expected fish taxa (4 of 7), and lack of violations of Class B(LR) WQ criteria in the sample collected during biocriteria sampling.
