Multiple manure spills in Wisconsin, including in Outagamie and Brown Counties and near Paullina, Iowa, have led to fish kills in Dutchman Creek and Mud Creek, respectively. Investigations by the Wisconsin Department of Natural Resources and Iowa DNR revealed manure entering waterways from dairy operations, causing environmental damage. Efforts are underway to contain the spills and determine the full extent of the impact on the water ecosystems. Recommendations to avoid affected waters have been issued, with ongoing investigations to identify the exact sources of the spills.
