DNR Monitoring Manure Spill Near Village Of Norwalk, Monroe County

Spring Valley Creek, Moore Creek And Kickapoo River Impacted

MADISON, Wis. – The Wisconsin Department of Natural Resources (DNR) is responding to a recent manure spill in Monroe County. Spill response began over the weekend and DNR staff continue to monitor the situation.

The DNR was first notified of the spill on Saturday, May 17, via a call to the DNR's Violation Hotline. An estimate of the amount of manure discharged is not currently available. 

The spill resulted in degraded water quality in Spring Valley Creek, Moore Creek and the Kickapoo, with fish kills observed in Spring Valley and Moore creeks. The number and species of fish killed has not yet been determined.

The spill originated southwest of Norwalk and continues moving down through the watershed. At this time, the DNR believes the spill was caused by rainfall washing manure off cropland where it had been applied earlier. 

The DNR is actively assessing opportunities for cleanup or mitigation.

More information on manure spills and manure spill prevention is available on the DNR's Manure Spills webpage.
