The plant discharges into Crow Creek, which flows into the South Platte River, part of the Platte River basin. This watershed is ecologically important for sustaining riparian habitats and supporting migratory bird populations along the Central Flyway. Downstream, the Platte River feeds into the Missouri River, ultimately reaching the Gulf of Mexico. The semi-arid climate makes water quality management critical for both human use and aquatic life.
