Assessment Comments
Assessment was based on occurrence of fish kill in August 1998.
Basis for Assessment
SUMMARY: The general aquatic life uses of this stream were considered "partially supported." EXPLANATION: A fish kill occurred in this tributary of Waterloo Creek on August 28, 1998, near Dorchester in Allamakee County. The kill was attributed to runoff of animal waste. An estimated 1,650 fish were killed (1,625 sculpins (Cottus spp.) and 25 brown trout (Salmo trutta). According to DNR's assessment methodology for Section 305(b) reporting, occurrence of a single pollution-caused fish kill within the most recent three-year period (1997-1999) indicates that the aquatic life uses of a waterbody are only "partially supported." Thus, the general aquatic life uses of this stream were assessed as "partially supported."
