HELENA, Mont. – The Bureau of Reclamation will begin a shoreline protection project at Canyon Ferry Reservoir in the spring of 2026 to improve visitor safety, protect natural resources and support long-term recreation access.
During construction, some campsites at Hellgate Campground and Court Sheriff Campground, along with the Cave Bay Day Use Area, will be temporarily closed. Affected sites will be unavailable for reservation through Recreation.gov while work is underway.
Planned closures include:
- Hellgate Campground: Sites 41–69
- Court Sheriff Campground: Sites 2, 3 and 12–48
These closures are necessary to allow construction activities to proceed safely and efficiently. Visitors using open sites in these campgrounds should expect increased vehicle and equipment traffic during the project period.
Reclamation will reopen campsites for reservation as soon as work is complete. Updates will be posted on Canyon Ferry’s website here and social media channels.
