Assessment Comments
Biocriteria sampling during 1996-1997.
Basis for Assessment
Used results from 6 DNR biocriteria samplings during 1996 and 1997 to assess support of the Class B(WW) aquatic life uses as FS. Biocriteria sampling shows a very diverse fish community with over 20 species from 5 families, presence of all the expcected fish taxa for Class B(LR) streams in the Iowan Surface subecoregion, and presence of smallmouth bass. This stream is relatively small, however, compared to other Class B(WW) streams and rivers, and the habitat to support adult game fish (i.e, smallmouth bass) is present but in limited amounts. Although pasturing impacts to the riparian zone have been noted in the past, the primary limitation to Class B(WW) uses is the naturally-occurring small size of the stream.
