Assessment Comments

Stream use assessment in July 1991.

Basis for Assessment

Used a review of the field sheet from the July 1991 DNR stream use assessment 4 mi SW of Garden Grove to upgrade the assessment of support of the Class B(LR) aquatic life uses from FST to FS due to (1) presence of a moderately diverse fish community (9 species from 3 families) for streams in the Central Irregular Plains (40) ecoregion, (2) presence of nearly all the expected fish taxa (7 of 8) for streams in this region, and (3) indications of much better than average habitat quality  for streams in this region (see above assessment developed for the 1994 305(b) report).   The field sheet for the July 1991 assessment indicates no significant threats to the continued support of the Class B(LR) uses.
