Assessment Comments
Assessment is based on results of an October 1994 DNR stream use assessment.
Basis for Assessment
Continue to use the assessment of support of the Class B(LR) aquatic life uses developed for the 1996 report. Follow-up monitoring is needed to determine the status of aquatic communities and habitats and to determine the degree to which the Class B(LR) uses may be impaired. A review of the field sheet from the October 1994 DNR stream use assessment shows a fish community of 4 species. Most of the expected species/genera of Class B(LR) stream in the Des Moines Lobe subecoregion were not present during this assessment (only 3 of the 11 expected fish taxa for Des Moines Lobe streams were present).
