Assessment Comments
1992 stream use assessment in Howard County.
Basis for Assessment
Used a review of the field sheet from the June 1992 DNR stream use assessment in Howard County to upgrade the assessment of support of the Class B(LR) aquatic life uses from PS to FST due to (1) presence of moderately diverse fish community (12 species from 3 families) for streams in the Iowan Surface subecoregion (47c) and (2) presence of a majority of the expected fish taxa (8 of 11) for streams in this subregion. Field sheet indicates diverse substrates and a few pool/riffe sequences but also indicates moderate impacts to the physical characteristics of this stream from frequent pasturing of the riparian zone and frequent streambank erosion. Despite these moderate impacts, the fish community present indicates that the Class B(LR) uses are fully supported.
