HELENA, Mont. — The Bureau of Reclamation plans to close access to all traffic across Canyon Ferry Dam on Montana State Highway 284, Wednesday, Nov. 8, from 8 a.m.- 3 p.m. to facilitate required repairs. The temporary road closure is necessary to repair one of the fixed wheel gates. The road closure was originally scheduled in October, but winter weather delayed the closure.

“This is a critical piece of equipment, and repairs must take place as soon as possible by using a crane on the dam crest,” said Dan Stremcha, Canyon Ferry Facility Manager. “It is important to note that despite the needed repairs, the dam is functioning as designed, and there is no threat to the public.”

Travelers must seek alternate routes, north and south of the dam during the closure period.

Construction on Canyon Ferry Dam began in May of 1948 and was completed in June of 1954. The dam, powerplant, and reservoir constitute the Canyon Ferry Unit. Canyon Ferry Reservoir offers a wide range of water resources, including flood prevention, hydropower generation, irrigation, fish and wildlife habitat, and recreation opportunities.
