AAA Editor Notes
Grand Coulee Dam is off SR 155. The dam harnesses the Columbia River for irrigation, power and flood control. Said to be one of the largest concrete structures in the world, it is 550 feet high, 500 feet wide at its base, 5,223 feet long and contains nearly 12 million cubic yards of concrete. Behind the dam Lake Roosevelt extends 151 miles upstream to the Canadian border. Twelve giant pumps lift water from this reservoir to Banks Lake.

The massive face is illuminated by a 36-minute laser light show presented during the summer. Good viewpoints for watching this spectacle are at the visitor center, at Douglas Park and Crown Point. The Grand Coulee Dam Visitor Center, on SR 155 on the west bank below the dam, has interactive displays. A 45-minute film, Man-made Marvel, details the dam's construction process. Visitors can take a guided 45-minute tour of the pump generating plant.

Purses, backpacks and packages are not permitted on the tour.

Guided tours are available. Time: Allow 2 hours minimum.
