Center Lagoon discharges into local streams that flow into the Missouri River, a major waterway in the Great Plains. The Missouri River supports a variety of fish species and provides critical habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting downstream water quality in the Missouri River basin and ultimately the Gulf of Mexico.
