The plant's discharge enters small tributaries within the Platte River basin, which flows eastward to join the Missouri River near Plattsmouth, Nebraska. The Missouri River then continues to the Mississippi River and the Gulf of Mexico. The local watershed supports diverse aquatic life, including fish species such as channel catfish and walleye, and provides habitat for migratory birds along the Central Flyway.
