Assessment Comments

Assessment is based on results of a May 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 (=FST).   As noted in the 1996 assessment, the number of fish species (=7) and families (=2) are relatively low for streams in the Des Moines Lobe subecoregion (47b), and only 5 of the 11 expected fish taxa for Des Moines Lobe streams were present in the 1994 stream use assessment.   Additional sampling with more a more effective gear type is needed to better determine the status of the aquatic communities.   Field sheet from the 1994 assessment indicates relatively high quality aquatic habitats.
