Assessment Comments
1995 biocriteria sampling site.
Basis for Assessment
Used a review of the field sheet from the 1991 DNR stream use assessment, and the results of the 1995 DNR biocriteria sampling, to upgrade the assessment of support of the Class B(LR) aquatic life uses from FST to FS due to (1) presence of relatively diverse fish community (22 species from 5 families (1995 biocriteria sampling)) for streams in the Iowan Surface subecoregion, (2) presence of all the expected fish taxa (11 of 11) for streams in this subregion, and (3) indications on the field sheet from the 1991 DNR stream use assessment of above average habitat quality and riparian conditions, with no significant impacts to the physcial characteristics of the stream.
