Assessment Comments

Stream use assessment in Delaware County.

Basis for Assessment

Used information from stream use assessment to assesss support of aquatic life uses as FST due to (1) relatively high habitat score (25), (2) due to field notes that suggest that low fish score (6) is "not representative of stream's aquatic potential," and (3) problems with using seines to smaple fish in a stream with coarse substrates.
