Assessment Comments

Stream use assessment.

Basis for Assessment

Created an upstream subsegment and downstream subsegment for this waterbody due to comments from previous assessments that signficant difference exist between upstream and downstream reaches of this stream.   Used a review of the field sheet from the July 1992 DNR stream use assessment SE of Eagle Grove to assess support of the Class B(LR) aquatic life uses as FS due to (1) presence of a relatively diverse fish community (19 species from 4 families) for streams in the Des Moines Lobe subecoregion, (2) presence of nearly all the expected fish taxa (9 of 11) for streams in this subregion, and (3) indications on the field sheet of relatively high quality aquatic habitats inlcuding diverse substrates, several pool/riffle sequences, and only isolated areas of channel alterations and streambank erosion.   The July 1992 assessment was conducted during a period of high water in Eagle Creek.   Additional monitoring should be conducted at lower flows to confirm the assessment of support of the Class B(LR) uses developed for this report.
