Assessment Comments

Stream use assessment in Delaware County.

Basis for Assessment

Stream assessment form indicates average habitat quality.   Very diverse substrate and numerous pool/riffle sequences were observed.  Frequent pasture use impacts and stream bank erosion also noted.  Natural riparian vegetation removed.   Relatively low diversity of fish observed, but seining was hindered by abundant coarse substrates.
