libbymt Completed: 1972 Height: 422' (129m) Length: 3,055' (931m) "Libby Dam is architecturally one of the strongest and most massive types of dam built today. The dam...was built to withstand an earthquake of up to 6.5 on the Richter scale with no structural damage. Forty-seven monolithic sections make up the dam, each one designed to stand on its own like individual dams. If one section were to fail, the other 46 would remain standing. Seismic monitoring equipment carefully monitors the dam for movement and structural integrity through one of the most thorough instrumentation systems in the United States." The town of Rexford and the Great Northern Railroad lines were relocated to make room for the reservoir. "Koocanusa Bridge, Montana's longest (2,437 feet) and highest (270 feet) bridge, was built to provide additional access across the north end of the reservoir." "Temperature of the Kootenai River below the dam is controlled to create ideal conditions for the growth and reproduction of trout" |
