JEFFERSON CITY, MO. -- The Missouri Department of Natural Resources investigated a sewage leak from a lagoon at Long Branch State Park that was reported on Monday.

Park staff contacted the department’s Northeast Regional Office to report the leak. The leak occurred after a muskrat dug a 1 inch hole in the side of the berm approximately 2 feet from the top of the outer lagoon berm.

The department’s regional office staff investigated the site today and determined the sewage entered an unnamed tributary to Long Branch Lake; however, due to the amount of flow, the wastewater was pooling below a road culvert that is adjacent to the lake and did not enter the lake. Park personnel took actions to stop the water flow from entering the lake and began repairing the lagoon berm.

On-site lagoons should be regularly maintained to prevent leaks from occurring. Homeowners should control vegetative growth to ensure necessary sunlight exposure and air movement. Grass should be mowed on a regular basis during the growing season. It is also not recommended to allow livestock to graze to keep the vegetation controlled as livestock can damage the berm. Owners should also keep trees from growing around the lagoons and install a fence around the area.

The release of untreated sewage from sewer systems represents a potential threat to public health and the environment.
