mouth (S6 T85N R11W Benton Co.) to confluence with unnamed tributary in NE 1/4 S7 T85N R11W Benton Co.
Assessment Comments
Three stream use assessments in Benton County.
Basis for Assessment
Continue to use the assessment of support of the Class B(LR) aquatic life uses developed for the 1994 report (PS). Fish communities at two of the three sites assessed for DNR stream use assessments in July 1991 (7 spp., 2 fams; 5 spp., 2 fams; and 3 spp; 1 fam) contain relatively few of the species typical of Class B(LR) streams in this region. Follow-up monitoring is needed to determine the status of the aquatic communities and habitats and to determine the degree to which the Class B(LR) aquatic life uses may be impaired. Because the information on which this assessment is based in more than 5 years old, changed the 305(b) assessment category from "monitored" to "evaluated."
