Coldwater Creek IA 01-UIA-280

Assessment Comments

Assessment is based on a 2002 summary of trout reproduction in Iowa streams prepared by the DNR Fisheries Bureau. See attached document for details.

Basis for Assessment

SUMMARY:  The Class B(CW) coldwater aquatic life uses were assessed as "fully supported / threatened" (minor impacts).   Fish consumption uses remain "not assessed."  EXPLANATION:  Based on results of the 1995 DNR biocriteria sampling (see above), and based on a summary of trout reproduction in Iowa streams prepared by the DNR Fisheries Bureau, the Class B(CW) uses were assessed as "fully supported / threatened."  According to Moeller (1999), Coldwater Creek is in the category of Iowa trout streams that have at least some documented natural reproduction but that are generally unable to maintain a viable trout population at this time.   Fish consumption uses remain "not assessed" due to lack of recent fish tissue monitoring in this stream reach.
