Frazer Lagoon Wastewater Treatment Plant, Frazer, Montana

Frazer Lagoon is a municipal wastewater treatment facility located in Frazer, Montana, a small community in Valley County. The plant serves a population of about 350 residents, reflecting its role in a rural setting. It operates under the regulatory framework of the United States Clean Water Act, which requires secondary treatment for municipal discharges to protect water quality. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 166.56 megaliters per year and an actual discharge volume of 113.56 megaliters per year, the facility operates below its capacity. This suggests adequate infrastructure for current demand, with room for future growth. The treated effluent from Frazer Lagoon is discharged into the local watershed, which ultimately drains into the Missouri River basin. The Missouri River is a major waterway that supports diverse aquatic life and provides water for agriculture and communities downstream. The plant's secondary treatment helps minimize nutrient and pollutant loads, contributing to the ecological health of the region.

Frazer Lagoon discharges into the local drainage network that flows into the Missouri River, a major tributary of the Mississippi River system. The Missouri River basin supports a variety of fish species, including pallid sturgeon and paddlefish, and provides critical habitat for migratory birds. The plant's secondary treatment reduces organic and nutrient pollution, helping to maintain water quality in this ecologically sensitive region.
