Assessment is based on a 1999 summary of trout reproduction in Iowa streams prepared by the DNR Fisheries Bureau.

Basis for Assessment

SUMMARY:  The Class B(CW) coldwater aquatic life uses were assessed as "fully supported."  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."  According to Moeller (1999), Ensign Creek is in the category of Iowa trout streams with long-term, consistent natural reproduction; these streams are capable of maintaining a viable population of trout without stocking.   Fish consumption uses remain "not assessed" due to lack of recent fish tissue monitoring in this stream reach.
