Discover the Chief Joseph Dam Tour in Washington

Explore one of the largest hydropower-producing dams in the United States with a visit to Chief Joseph Dam, located along the Columbia River near Bridgeport. This behind-the-scenes tour offers a fascinating look at large-scale hydroelectric engineering, river management, and renewable energy production — all while standing at the foot of an immense concrete structure that spans the river in powerful silence.

Why it’s special:
Chief Joseph Dam is one of the nation’s top hydroelectric producers and a critical part of the Columbia River power system. Few places offer such close access to massive turbines, spillway structures, and powerhouse operations, making this a rare educational and engineering-focused experience.

History / Story of Chief Joseph Dam

Constructed between 1950 and 1955 and later expanded in the 1970s, Chief Joseph Dam was built by the U.S. Army Corps of Engineers to generate power, support flood control, and help regulate the Columbia River. Named after the Nez Perce leader Chief Joseph, the dam represents both engineering achievement and a complex history of regional development, tribal lands, and river ecology. Today, it remains a key contributor to renewable energy in the Pacific Northwest.
