Assessment Comments

Assessment is based on results of a November 1994 DNR stream use assessment.

Basis for Assessment

Used a review of the field sheet from the 1994 DNR stream use assessment in Webster County to downgrade the asessment of support of the Class B(LR) aquatic life uses from FST to PS due to (1) relatively low fish community diversity (5 species from 3 families) for streams in the Des Moines Lobe subecoregion and (2) presence of less than a majority of the expected fish taxa (5 of 11) for streams in this subregion.   As with the DNR stream use assessments for other streams in this portion of the upper Des Moines basin, rocky substrates and numerous snags hindered effective sampling (seining) of the fish community.   Follow-up monitoring is needed to better define the status of the aquatic communities and habitats and to determine the degree to which the Class B(LR) uses may be impaired.   The field sheet indicates above average habitat quality, with no significant threats to the physical characteristics of this stream.
