The state has ordered a Fond du Lac County dairy to improve its monitoring systems after a Memorial Day weekend release of about 50,000 gallons of manure.
The materials released May 26 at Lake Breeze Dairy flowed into the waters of Pipe Creek and then Lake Winnebago.
The state issued a “notice of violation” against the dairy. State and dairy staff then met to discuss the incident, according to Casey Jones, DNR agricultural runoff management specialist.
The dairy revised its spill response plan, agreed to have more staff monitoring spreading operations, will limit application after dark, and improve checks of manure lagood levels.
The DNR has not decided yet if it will ask the state Dept. Of Justice to seek monetary penalties in civil court, Jones said.
