Assessment Comments

Stream use assessment .

Basis for Assessment

Used results of the October 1990 DNR stream use assessment to assess support of the Class B(LR) aquatic life uses as FST due to (1) indications on field sheet of diverse substrates, several pool/riffle sequences, only isolated channel alterations, and moderately stable stream banks, (2) moderately diverse fish community (11 species, 4 families) (although most species collected are pollution tolerant), and (3) riparian corridor is timbered through most of the B(LR) reach.   Field sheet suggests that threats to the continued support of the aquatic life uses include possible water quality impact due to the Altoona wastewater treatment plant (odor of effluent noticed during surveys) and over pasturing of riparian zone in the general use reaches.
