Assessment Comments

Assessment is based on results of an IDNR stream use assessment conducted in September 1995.

Basis for Assessment

SUMMARY:  The Class B(WW) aquatic life uses remain assessed as "fully supported" based on results of an IDNR stream use (biological) assessment in 1995.   The assessment category, however, is changed from "monitored" to "evaluated."  Fish consumption uses remain "not assessed" due to the lack of fish contaminant monitoring in this river segment.  

EXPLANATION:  Continue to use the assessment developed for the 1998 report that was based on results of the 1995 IDNR stream use assessment.   However, because these data are now considered too old to accurately characterize current water quality conditions, the assessment category is changed from "monitored" (indicating an assessment with relatively high confidence) to "evaluated" (indicating an assessment with relatively low confidence).  

Fish consumption uses remain "not assessed" due to the lack of fish contaminant monitoring in this stream segment.
