Grand Coulee Dam is a
gravity dam on the
Columbia River in the U.S. state of
Washington built to produce
hydroelectric power and provide irrigation. It was constructed between 1933 and 1942, originally with two powerplants. The Third Powerplant was completed in 1974 to increase its electric potential. It is the largest
electric power-producing facility in the United States. The dam's power plants fueled the growing industries of the Northwest U.S. during
World War II. Between 1967 and 1974, the Third Powerplant was constructed in conjunction with the dam and in addition to the original two power houses. Through a series of upgrades and the installation of
pump-generators, the dam now supplies four power stations with an installed capacity of 6,809
MW. The
reservoir is called
Franklin Delano Roosevelt Lake, named after the United States President who presided over the authorization and completion of the dam. The dam has also prevented the migration of
salmon and other fish upstream to spawn, interrupting their habitat and reproductive cycle. (more...)
