Assessment Comments

Assessment is based on a 2002 IDNR summary of trout reproduction.

Basis for Assessment

SUMMARY:  The Class B(CW) coldwater aquatic life uses remain assessed as "fully supported / threatened" (minor  impacts).   Fish consumption uses remain "not assessed."  EXPLANATION:  Based on the assessment developed for the 2000 report (see above), and based on an updated summary of trout reproduction in Iowa streams prepared by the DNR Fisheries Bureau in April 2002, the Class B(CW) uses remain assessed as "fully supported / threatened."  According to the updated summary, this reach of Dousman Creek is in the category of Iowa trout streams that exhibit recent, but inconsistent reproductive success and that are generally not capable of maintaining a viable population for the target trout species at this time.   Fish consumption uses remain "not assessed" due to lack of fish tissue monitoring in this stream reach.
