Occurance of fish kill August, 1998.
Basis for Assessment
SUMMARY: The general aquatic life uses of this stream were assessed as "partially supported." EXPLANATION: A fish kill occurred on Crabapple Creek on August 6, 1998. This kill was attributed to agricultural runoff of animal waste from a cattle lot. Approximately 3.2 miles of stream were affected; an estimated 26,500 fish were killed, with over 100 smallmouth bass reported killed. (A fish kill was also reported for this reach of Crabapple Cr. on June 26, 1995; the kill was caused by runoff from a feedlot; an estimated 11,800 fish were killed.) 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 river reach were assessed as "partially supported."
