Assessment Comments

Assessment is based on an IDNR investigation of a fish kill in August 2002.

Basis for Assessment

SUMMARY: The Class B(LR) aquatic life uses are assessed (monitored) as “partially supported" due to occurrence of a fish kill in August 2002. This kill is believed to have been caused by animal waste.

EXPLANATION: The fish kill occurred on August 24, 2002, near the intersection of 255th Avenue and 310th Street; the kill was localized to an approximately 40-meter segment of stream; approximately 100 fish were killed. The kill was believed to be caused by manure. According to IDNR's assessment methodology for Section 305(b) reporting, occurrence of a single pollution-caused fish kill within the most recent three-year period indicates ongoing impairment of the aquatic life uses.
