Assessment Comments

Assessment is based on a survey of trout reproduction.

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 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), this reach of Bankston 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.
