The Wisconsin Department of Natural Resources is responding to a manure spill reported in Kewaunee County, East of Casco, along Highway 54.

The DNR was notified Friday morning, Jan. 9, of manure discharging from a field operated by El-Na Farms into a stream that feeds into Rio Creek, where bass fishing is prevalent. Officials say the discharge appears to have been caused by overnight heavy rainfall (appx. 0.7 inches), which washed manure off cropland where it had recently been applied.

DNR staff has been on site since Friday to monitor the situation, while the farm worked to clean up the discharge and prevent further runoff. Officials say no additional impacts have been reported at this time.

The DNR encourages farmers and the public to review best practices for manure application and spill prevention.
