Unnamed Creek (near Hazleton) IA 01-WPS-394
mouth (NE 1/4 SW 1/4 S28 T90N R9W Buchanan Co.) to headwaters in S26 T90N R9W Buchanan Co.
Assessment Comments
Assessment is based on occurrence of a fish kill in August 2001.
Basis for Assessment
The general aquatic life uses are assessed (evaluated) as "partially supported" due to occurrence of a fish kill. EXPLANATION: A fish kill occurred on this stream segment on August 18, 2001. The kill affected 1 miles of this unnamed tributary to Otter Creek in sections 33 and 28 to T90N, R9W, Buchanan County approximately 3 miles south of Hazleton. The kill was caused by movement of land-applied hog manure and waste milk to this unnamed creek. This kill was not related to rainfall runoff. According to DNR's assessment methodology for Section 305(b) reporting, occurrence of a single pollution-caused fish kill during the most recent three-year period (1998-2001) indicates "partial support" of the aquatic life uses. Thus, the general aquatic life uses of this stream segment were assessed as "partially supported."
