Assessment Comments

1990 stream use assessment in Dubuque County.

Basis for Assessment

Used a review of the field sheet from the August 1990 DNR stream use assessment in Dubuque County to continue to assess support of the Class B(LR) uses as PS due to (1) relatively poor fish community diversity (4 species from 2 families) for streams in the Driftless Area ecoregion, (2) presence of only 1 of the 9 expected fish taxa for streams in this region, and (3) indications on field sheet of relatively poor quality aquatic habitats (see 1994 assessment).  The data upon which this assessment is based are more than 5 years old.  Follow-up monitoring is needed to update this assessment, to determine the status of the aquatic communities and habitats at this site and at other sites in the Class B(LR) reach, and to determine the degree to which the Class B(LR) uses may be impaired.
