Assessment Comments

Stream use assessment in Delaware County.

Basis for Assessment

Changed assessment from PS (in 1994) to FST due to diversity of substrates, frequent pool/riffle sequences, and poor seining efficiency due to coarse substrates.   Stream apparently threatened by pasturing but habitat quality suggests that stream is not impaired.
