Assessment Comments

Stream use assessment in November 1990.

Basis for Assessment

Continued to use the assessment of support of the Class B(LR) aquatic life uses developed for the 1996 report (=FST).   Review of field sheet from the November 1990 DNR stream use assessment shows that a slight majority (5 of 9) of the expected fish taxa for the Central Irregular Plains (40) ecoregion was present.   In addition to channelization, also include the influence of a wastewater treatment facility as a potential threat to the continued support of the Class B(LR) uses as noted on the DNR field sheet.
