Assessment Comments

Assessment is based on a 2006 summary of trout reproduction in Iowa streams prepared by the DNR Fisheries Bureau.

Basis for Assessment

SUMMARY:  SUMMARY:  The Class B(CW) coldwater aquatic life uses are assessed (monitored) as "fully supported" based on the May 2006 summary of trout reproduction in Iowa streams as prepared by the IDNR Fisheries Bureau.   Fish consumption uses remain "not assessed".  

EXPLANATION:  Based on an updated summary of trout reproduction in Iowa streams prepared by the DNR Fisheries Bureau in May 2006, the Class B(CW) uses are assessed as "fully supported".   According to the updated summary, Richmond Springs is in the group of Iowa coldwater streams that supports natural reproduction of trout.   Based on results of surveys by the IDNR Fisheries Bureau, this stream is placed in the category of Iowa trout streams that have fairly consistent natural reproduction and that are capable of maintaining a viable population for the target trout species without any stocking.   This assessment is consistent with previous assessments of the ability of this stream to support natural reproduction of trout.

Fish consumption uses remain "not assessed" due to lack of fish tissue monitoring in this stream reach.
