Long Creek IA 05-GRA-1364

Assessment Comments

Assessment based on biocriteria data and two stream use assessments in July 1991.

Basis for Assessment

Continued to use the assessment of support of the Class B(LR) aquatic life uses developed for the 1994 and 1996 reports (=FST).   A review of the field sheets from the two DNR stream use assessments in July 1991 shows relatively diverse fish communities (14 species from 4 families and 11 species from 4 families) for streams in the Central Irregular Plains (40) ecoregion, while results of the 1995 biocriteria sampling in the DeKalb Wildlife area showed a very diverse fish community of 21 species from 6 families.   Results of biological monitoring at all three locations show that a majority of the expected fish taxa for streams in this region are present (7 of 8, 5 of 8, and 7 of 8).   Field sheets from the 1991 DNR stream use assessments indicate that frequent channel alterations in the upper portion of the Class B(LR) reach may threaten support of the Class B(LR) uses; otherwise no significant threats to the Class B(LR) uses were noted.
