PUBLIC NOTICE: Black Eagle Dam Drawdown & Park Irrigation Impacts
Beginning July 31 through approximately mid-September, NorthWestern Energy will temporarily lower the Missouri River at Black Eagle Dam while critical repairs and upgrades are completed.
As a result, several City Park & Recreation facilities that rely on river water for irrigation may experience reduced watering capacity, including:
• Anaconda Hills Golf Course
• Eagle Falls Golf Course
• Montana Veterans Memorial Park
• Voyagers Stadium
• Gibson Park
• Elks Riverside Park
• Tourist Park
• Electric City Water Park
During this time, you may notice:
*Irrigation occurring at unusual times, including during the day.
*Grass and landscaped areas appearing drier than normal.
Our crews will prioritize watering high-use areas, trees, and other critical landscapes while making the best use of the limited water available.
We appreciate NorthWestern Energy and Sletten Construction for working closely with the City to help minimize impacts, and we thank our community for your patience and understanding while this important infrastructure project is completed.
