Assessment Summary
The Class BWW2 use was assessed (evaluated) as "WINFOI" based historical biological sampling data and habitat assessment. All other designated uses were "not assessed."
Assessment Explanation
Presumptive Class A1 - No Data Class BWW2 - Biological Sampling: The aquatic life use was assessed (evaluated) as "WINFOI" due to (1) presence of a relatively depauperate fish community (7 species from 2 families) for streams in the Des Moines Lobe sub-ecoregion (47b) and (2) presence of less than a majority of the expected fish taxa (4 of 11) for streams in the 47b sub-ecoregion, and (3) indications on the field sheet of extensive channel alterations due to channelization and generally poor quality aquatic habitats. Follow-up monitoring is recommended to determine the status of the aquatic communities and habitats of this stream and to determine the degree to which the aquatic life use may be impaired.
