Fargo Valley City, ND, November 7, 2026 — The state of North Dakota is confronting the arrival of an invasive species in one of its major recreational water bodies. Zebra mussels have been detected for the first time in Lake Sakakawea, according to officials with the North Dakota Game and Fish Department.
The discovery was made in the eastern portion of the lake. This marks the initial confirmed presence of zebra mussels in Lake Sakakawea, a significant reservoir located in central North Dakota. Zebra mussels are small, hard-shelled mollusks native to freshwater lakes in Eurasia. They are known for their rapid reproduction and ability to attach to hard surfaces, which can clog water intake pipes and damage boats.
In response to this detection, the North Dakota Game and Fish Department is initiating new strategies focused on mitigation and public education. The department is emphasizing the critical role that watercraft users play in preventing the further spread of this invasive species. Preventing the movement of zebra mussels from one body of water to another is a key component of managing their impact.
Officials are urging all individuals who use boats or other watercraft on Lake Sakakawea, or any other North Dakota water body, to follow established decontamination procedures. These typically include cleaning, draining, and drying watercraft and equipment after leaving a water access point. The goal is to ensure that mussels, their larvae, or eggs are not transported to new locations.
The specific timeline of when the zebra mussels first appeared in the lake was not provided. Further details regarding the extent of the infestation or the exact location within the eastern part of the lake were also not immediately available. The Game and Fish Department is expected to provide more information and guidance to the public as assessments continue. The detection underscores the ongoing challenge of managing invasive species in North Dakota’s aquatic ecosystems and highlights the shared responsibility in protecting native environments and infrastructure from their detrimental effects.
