Stream use assessment in Delaware County.

Basis for Assessment

Used a review of the field sheet from the October 1991 DNR stream use assessment in Delaware county to change the assessment of support of the Class B(LR) aquatic life uses from FST to "not assesse" due to lack of sufficient information on the aquatic communities of this stream.  Only one fish species was captured with seines due to rocky substrates in this apparently high quality stream reach.  Field sheet indicates high quality aquatic habitats, including very diverse substrates, numerous pool/riffle sequences, and only isolated impacts to the physical characteristics of the stream due to pasturing of the riparian corridor.  Additional monitoring is needed to better define the status of aquatic communities of this stream and to provide the information necessary to develop an accurate assessment of the support of the Class B(LR) uses.
