Assessment Comments
1997 biocriteria sampling: Fish 23 spp., 5 fams. Fish IBI= 79(good), BM-IBI= 60(good).
Basis for Assessment
Used results of the August 1997 DNR biocriteria sampling 5.5 miles NW of Quasqueton to assess support of the Class B(LR) aquatic life uses as FS due to (1) presence of a very diverse fish community (23 species from 5 families) for the Iowa Surface subecoregion with relatively large numbers of individuals per species (over 1,400 fish captured during sampling, thus indicating a very productive stream), (2) presence of all expected fish taxa (11 of 11) for streams in this subecoregion, and (3) lack of violations of Class B(LR) WQ criteria in the sample collected during biocriteria sampling.
