The plant discharges into streams that flow into the Mississippi River, one of the largest river systems in North America. The Mississippi River and its tributaries support a wide range of fish and wildlife, including migratory birds and endangered species. Protecting water quality in this basin is critical for maintaining ecological health and ensuring safe water for communities downstream.
