Boyer River IA 06-BOY-1502
from confluence with Willow Cr. (S28 T78N R44W Harrison Co.) to the Harrison-Crawford county line.
Assessment Comments
Assessment is based on results of IDNR ambient quarterly water quality monitoring near Missouri Valley in 1996-1997.
Basis for Assessment
Changes the assessment of support of the Class B(WW) uses from PS to FST due to results from the DNR quarterly WQ monitoring station E of Missouri Valley: no violations of either toxic or conventional contaminants occurred in the eight samples collected over the October 95 to July 97 period. This assessment was developed without the benefit of information on the status of the aquatic communities in this reach of the Boyer River. Additonal monitoring is needed to determine the status of the aquatic communities and habitats of this reach of river.
