Assessment Comments

One 1991 stream use assessment south of Elkport in Clayton County.

Basis for Assessment

Used results of the October 1991 DNR stream use assessment to assess support of the Class B(WW) aquatic life uses as FST due to (1) habitat score (32) far better than the overall median score (22) for DNR stream use assessments, (2) excellent low flow characteristics (ie, ability to maintain good aquatic habitat at low flows), and (3) indications on field sheet of very diverse substrates, numerous pool/riffle sequences, only isolated channel alterations, and moderately stable stream banks.  Results of fish sampling were inconclusive due to difficulty of sampling such wide and deep habitats with a small (4' x 15') seine.  Field sheet suggests that continued support of the aquatic life uses is threatened by pasturing of the riparian zone.
