Assessment Comments

Insufficient information available to develop assessments. Previous assessments were based on results of IDNR biological monitoring in 1994 and 1995.

Basis for Assessment

SUMMARY:  The Class B(WW) aquatic life uses are considered "not assessed" due to the age of the biological data upon which the previous assessments of these uses ("fully supported") were based.   Fish consumption uses remain "not assessed" due to the lack of fish contaminant monitoring in this river segment.  

EXPLANATION:  The 2004 assessment of the Class B(WW) uses for this stream segment ("fully supported") was based on (1) results of biological monitoring conducted as part of an IDNR stream use assessment in 1995 and (2) results of IDNR/UHL biological (biocriteria) monitoring in 1994.   Because the data upon which this assessment was originally based have aged beyond 10 years--and are thus considered too old to characterize current water quality conditions--the Class B(WW) uses of this segment are now considered "not assessed".   Thus, this stream segment is moved from IR Category 2a to 3a (insufficient information to assess any uses).  

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