Canyon Ferry Dam, Hydroelectric power station and gravity dam in Lewis and Clark County, Montana.
Canyon Ferry Dam extends 305 meters across the Missouri River, generating 49.8 megawatts of electricity while creating a substantial water reservoir.
The Bureau of Reclamation constructed Canyon Ferry Dam in 1949, replacing an earlier timber crib structure from 1898 built by Helena Water and Electric Power Company.
The reservoir supports Montana fishing traditions with populations of trout and walleye, drawing anglers from surrounding communities throughout the year.
The dam contains four radial spillway gates capable of discharging 150,000 cubic feet of water per second, managing water flow for downstream communities.
Three Francis turbine generators within the power plant structure produce 277 million kilowatt-hours of electricity annually from the Missouri River flow.
