Grand Coulee Dam, Hydroelectric power station on Columbia River, Washington, US
The Grand Coulee Dam extends 1,592 meters across the Columbia River, containing three power plants that generate electricity for millions of households in Washington State.
Construction started in 1933 during the Great Depression and finished in 1942, requiring 40 million cubic yards of material to create this engineering achievement.
The dam's construction displaced Native American communities and submerged traditional fishing grounds, leading to changes in regional indigenous practices.
Visitors access guided tours at the dam's visitor center, which presents exhibits about power generation, water management, and regional development.
The facility set a generation record of 6,007 megawatt-hours in one hour on June 20, 2002, while maintaining 110,000 megawatt-hours for the entire day.
