Assessment Comments

Assessment is based on (1) results of monitoring of fish, macroinvertebrates, habitat & water quality as part of the Sny Magill / Bloody Run project and (2) DNR summary of trout reproduction. Highlighted in Iowa Conservationist.

Basis for Assessment

Used results of monitoring for fish, water quality, habitat, and aquatic macroinvertebrates presented in Seigley et al. (1996) (Sny Magill nonpoint source pollution monitoring project, Clayton County, Iowa: water year 1994, DNR/ GSB Technical Information Series 36) to assess the B(CW) aquatic life uses as FST. Water quality data, however, suggest that episodes of low DO occur on both this stream and Sny Magill. Aquatic community does not reflect any low DO/organic enrichment impact. Causes of low DO may be related to runoff events, but issue needs further study. Stream highlighted as a trout stream in the March/April 1996 issue of the Iowa Conservationist.
