Middle Raccoon River IA 04-RAC-1190

Assessment Comments

Assessment is based on results of an October 1997 DNR fish survey.

Basis for Assessment

SUMMARY:  The Class A (primary contact recreation) uses remain "not assessed."  The Class B(WW) aquatic life uses remain assessed as "fully supported / threatened" (minor impacts).   Fish consumption uses remain "not assessed."  EXPLANATION:  The Class A uses remain "not assessed" due to the lack of water quality information for this segment upon which to base an assessment.   The Class B(WW) aquatic life uses remain assessed as "fully supported / threatened " based on results of the biological monitoring conducted by IDNR on this stream segment in 1997 (see assessment for the 2000 report above).   These data are less than five years old and, according to IDNR's methodology for Section 305(b) assessments, are thus appropriate for characterizing current water quality conditions.   Fish consumption uses remain "not assessed" due to the lack of fish contaminant monitoring in this stream segment.
