Assessment Comments
Assessment is based on results of an IDNR investigation of a fish kill in April 2000.
Basis for Assessment
SUMMARY: The Class B(LR) aquatic life uses are assessed (monitored) as "partially supported" based on occurrence of a fish kill in April 2000. This assessment is the same as that developed for the 2002 reporting cycle.
EXPLANATION: A fish kill occurred on this stream segment on April 6, 2000. The kill affected 6.5 miles of Deer Creek beginning at the Iowa/Minnesota state line and extending downstream at the west line, S35, T100N, R19W, Worth County; an estimated 59,000 fish were killed. The kill was caused by a fertilzer spill at an ag-chemical dealer in Myrtle, MN. 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 Class B(LR) aquatic life uses of this stream segment were assessed as "partially supported."
