Assessment Comments
Stream use assessment in October 1990.
Basis for Assessment
Used a review of the field sheet from the October 1990 DNR stream use assessment approximately 2 mi NW of Greenfield to upgrade the assessment of support of the Class B(LR) aquatic life uses from PS to FST due to (1) presence of a majority of the expected fish taxa (5 of 6) for streams in the Missouri River portion of the Southern Iowa Rolling Loess Prairies subecoregion, (2) presence of a regionally typical fish community with relatively low diversity (7 species from 2 families), and (3) indications on the field sheet of relatively few habitat problems, with a fairly well-meandered channel form and relatively stable stream banks. The data upon which this assessment is based is well over 5 years old. Additional monitoring is needed to update the assessment and to determine the status of the aquatic communities and habitats.
