Gackle Lagoon Wastewater Treatment Plant, Logan County, North Dakota

Gackle Lagoon is a wastewater treatment facility located near the Gackle Municipal Airport in Logan County, North Dakota. It serves a small population of 310 residents, reflecting the rural character of the area. The plant operates under the regulatory framework of the United States Clean Water Act, which requires secondary treatment for municipal wastewater discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 113.56 megaliters per year and a similar discharge volume, the facility operates at full capacity to meet the needs of the local community. As a small agglomeration, it is subject to state-level NPDES permitting under EPA oversight. The treated effluent is discharged into the local watershed, which drains into the Missouri River basin. This waterway supports diverse aquatic life and is an important resource for agriculture and recreation in the region. The plant's operation helps protect downstream water quality in this semi-arid prairie environment.

The treated effluent from Gackle Lagoon enters the local drainage network, which flows into the Missouri River system and ultimately reaches the Mississippi River and the Gulf of Mexico. The surrounding prairie ecosystem relies on healthy water quality to support native fish species and migratory birds. The plant's secondary treatment reduces nutrient loading, helping to prevent eutrophication in downstream water bodies.
