Шаблон:Infobox dam Cabinet Gorge Dam is a concrete gravity-arch hydroelectric dam in the northwest United States, on the Clark Fork River in northern Idaho. The dam is located just west of the Montana border and the Cabinet Gorge Reservoir extends into Montana, nearly to Noxon Rapids Dam. The purpose of the dam is for hydroelectricity.

Construction

Construction began in 1951 by the Morrison–Knudsen Corporation, with groundbreaking ceremonies on April 1.[1][2][3]

The Clark Fork River had to be diverted with two coffer dams and speed was necessary because spring flooding threatened the river diversion and coffer dam integrity. Thirty-two tons of dynamite was used to blast Шаблон:Convert of rock from the canyon walls in order to prep the construction site. Water was diverted through two Шаблон:Convert tunnels, and a Шаблон:Convert of earth was excavated from the site overall. Construction on the dam was completed in 1952 in half the estimated time.[4]

The dam is currently owned and operated by the power company Avista, formerly Washington Water Power.

On August 13, 2017, a train derailment dumped more than 3,500 tons of coal on the Cabinet Gorge Reservoir riverbank between Noxon and Heron, Montana.[5]
