Assessment Comments

1991 stream use assessment at Hwy 3 Bridge in Delaware County.

Basis for Assessment

Used results of the November 1991 DNR stream use assessment near Colesburg to assess support of the Class B(LR) aquatic life uses as FST due to (1) habitat score (22) equal to the overall median habitat score for DNR stream use assessments, (2) indications on field sheet of diverse substrats, several pool/riffle sequences, only isolated channel alterations (pasturing of riparian zone), and relatively stable stream banks, and (3) comments on field sheet regarding "nice deep pools and riffle areas." Field sheet suggests that pasturing of the riparian zone threatenes the continued support of the aquatic life uses.
