Manure runoff from a dairy farm in Manitowoc County is affecting water quality in Pine Creek as it flows through the town of Newton, about five miles south of Manitowoc. The Wisconsin Department of Natural Resources responded Monday evening to a complaint about a potential spill in the creek, which flows into Lake Michigan. The amount of runoff entering the stream is unknown and the impacts downriver are still being investigated at this time. The farm is working with DNR staff to address the issue and the source from the manure pit has been controlled. Agriculture specialists with the DNR will continue to monitor water quality in the creek.
