Onsite Comments

Roora Dairy of Paullina was land applying manure in a field, which entered a blown-out tile that discharges to Mud Creek. Fish kill originated from manure entering a broken tile and then draining to Mud Creek. Dead fish were observed along 16,900 yards from the tile outlet (42.988447, -95.771877) to the confluence with Mill Creek (42.956489, -95.70631).
