Gardner Lagoon Wastewater Treatment Plant, Cass County, North Dakota

Gardner Lagoon is a wastewater treatment facility located in Gardner Township, Cass County, North Dakota, within the Red River Valley region. The plant serves a small rural community of approximately 74 residents, providing essential sanitation services for this agricultural area. The facility operates at the secondary treatment level, which is the standard requirement under the U.S. Clean Water Act for municipal wastewater treatment. With a designed capacity of 37.85 units (likely million gallons per day or similar), the plant manages the wastewater generated by the local population, ensuring compliance with federal and state environmental regulations. The treated effluent from Gardner Lagoon is discharged into nearby surface waters, which ultimately drain into the Red River of the North. This river flows northward into Canada, eventually reaching Lake Winnipeg. The plant plays a critical role in protecting local water quality and the downstream aquatic ecosystem, which supports diverse fish and wildlife species in the Red River Basin.

Gardner Lagoon discharges into local streams that are part of the Red River of the North watershed. The Red River flows north through North Dakota and Minnesota into Manitoba, Canada, and empties into Lake Winnipeg. This basin supports important agricultural drainage and provides habitat for migratory birds and fish species such as walleye and northern pike. The plant's secondary treatment helps reduce nutrient loads that could contribute to eutrophication in downstream waters.
