Michigan Lagoon is a wastewater treatment plant located in Michigan City, North Dakota, serving a small population of 294 residents. The plant operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal wastewater discharges. As a small facility, it plays a crucial role in protecting local water quality in the rural setting of Nelson County. The plant provides secondary treatment, a standard level for small communities in the United States. Its designed capacity is 302.83 cubic meters per day, with an average daily discharge of 151.42 cubic meters, indicating it operates well within its capacity. The treated effluent is discharged into local waterways that drain into the Red River Basin, ultimately reaching Lake Winnipeg via the Red River.

The treated effluent from Michigan Lagoon flows into local streams within the Red River Basin, which drains northward into Lake Winnipeg in Manitoba, Canada. This watershed is ecologically significant as it supports migratory waterfowl, fish species, and agricultural irrigation. The plant's secondary treatment helps reduce organic pollutants and nutrients, mitigating the risk of eutrophication in downstream water bodies.
