Assessment Comments

Stream use assessment in Clayton County.

Basis for Assessment

Stream assessment form indicates fair habitat quality.  Frequent pasture use impacts were observed including frequent bank erosion.   Very diverse substrates and several pool/riffle sequences noted.   Relatively low diversity of fish observed; however, seining may have been hindered by abundant rocky substrates.
