The plant's discharge enters local streams that feed into the Missouri River, a major tributary of the Mississippi River. This watershed supports diverse aquatic life and provides drinking water for communities downstream. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting the ecological health of the river system and the Gulf of Mexico, which experiences seasonal hypoxia from nutrient loading.
