Assessment Comments
June 1996 SUA: habscr/fshscr: 27/11 (seine). 1996 biocriteria: IBI=38, 23 spp., 6 fams. 1996 Biocriteria: Fish IBI=70 (good), BM-IBI=70 (good).
Basis for Assessment
Used results of the July 1996 DNR biocriteria sampling NW of Lehigh at Dolliver State Park to upgrade the assessment of support of the Class B(LR) aquatic life uses from FST to FS due to (1) existence of very diverse fish community of 23 species from 6 families, (2) presence of nearly all the expected fish taxa for streams in the Des Moines Lobe subecoregion (10 of 11), and (3) lack of violations of Class B(LR) water quality criteria in the sample collected during biocriteria sampling.
