Assessment Comments

Assessment based on results of July 1994 IDNR stream use assessment conducted in Plymouth county.

Basis for Assessment

Not assessed for the 1994 report (not designated for Class B(LR) uses until 1995).  

Used results of the July 1994 DNR stream use assessment to assess support of the Class B(LR) aquatic life uses as FST due to (1) habitat score (23) better than the overall median score (22) for stream use assessments, (2) indications on field sheet of diverse substrate, several pool/riffle sequences, and (3) comment on field sheet of "nice habitat in pool/riffle areas."  Field sheet indicates that support of the aquatic life uses is treatened by pasturing of riparian area.  Very few fish found; assume that this is due to problems with seining and/or transient conditions.
