Assessment Comments
1995 biocriteria sampling site.
Basis for Assessment
Used data from one biocriteria sampling location in Benton County. Fish and habitat data metrics from stream use assessment protocol were used to make use support determination. Results of July 1991 DNR stream use assessment support assessment based on biocriteria sampling; i.e., habitat score (28) much better than overall average score for DNR stream use assessments, fish score (10) equal to the 75th percentile score for stream use assessments made with seines, and field notes that state "very nice rock riffles and pooled areas."
