The plant's discharge enters the Big Blue River watershed, which flows into the Platte River and then the Missouri River. This river system supports diverse aquatic life and provides water for irrigation and recreation in Nebraska. The surrounding area is predominantly agricultural, so nutrient management is important to prevent downstream eutrophication.
