Assessment Comments

Three stream use assessments in Benton County.

Basis for Assessment

Stream assessment forms indicate somewhat below average habitat quality.   Frequent pasture use impacts noted at all 3 assessment locations.   Two of three locations had relatively low diversity of substrate and few pool/riffle sequences.   Relatively low diversity of fish observed at all assessment locations.   Map suggests stream has been straightened in many reaches.
