Choteau Lagoons is a municipal wastewater treatment plant located in Teton County, Montana, United States. The facility serves a population of approximately 1,780 residents, reflecting a small community in the rural landscape of north-central Montana. As a lagoon-based system, the plant provides natural treatment through settling and biological processes. Under the U.S. Clean Water Act, small wastewater facilities like this are typically regulated through state-level NPDES permits, which set effluent limits to protect receiving water quality. The plant's design and operation align with standard practices for small agglomerations in rural areas. The treated effluent is discharged into local streams that drain into the Teton River, a tributary of the Marias River, which ultimately flows into the Missouri River system. This watershed supports agricultural irrigation, livestock watering, and aquatic habitats for species such as trout and migratory waterfowl. Proper treatment is essential to prevent nutrient loading and maintain the ecological health of these downstream waters.
Environmental context
The plant discharges into local waterways that feed the Teton River, part of the Missouri River basin. This watershed supports diverse aquatic life, including trout and other cold-water species, and provides water for agriculture and recreation. Downstream, the Marias River and Missouri River are important migratory corridors for birds and fish. Effective wastewater treatment helps prevent eutrophication and protects these ecological functions.
