Tiber Dam, Embankment dam in Liberty County, Montana
The Tiber Dam stretches 4,300 feet across the Marias River, creating Lake Elwell with its 180-mile shoreline and multiple recreational areas.
Construction of the Tiber Dam began in 1952 and concluded in 1956, followed by additional structural improvements between 1976 and 1989 to address erosion concerns.
The dam and its reservoir serve as a central gathering point for local residents who participate in fishing tournaments and outdoor activities throughout the seasons.
Visitors can access multiple boat ramps and camping facilities around Lake Elwell, with the nearest services available in the town of Chester.
The structure contains 9,800,000 cubic yards of material and features two spillways capable of handling a combined flow of 74,312 cubic feet per second.
