Rocky Reach Dam, 7 mi. n. to 6001 US 97A, is a Z-shaped structure 2,860 feet long. A viewpoint enables visitors to watch migrating fish ascend the mile-long juvenile fish bypass. In the powerhouse is the Museum of the Columbia, which traces life along the river beginning 10,000 years ago and also covers the history of local railroads. Other displays include portraits of Nez Perce Indians, Thomas Edison memorabilia, an overlook onto the generation floor and changing art exhibits.
The Rocky Reach Visitor Center has exhibits about dam building and a fish viewing area. Movies are shown throughout the day in the 90-seat theater. Gardens, picnic shelters and a playground are on the grounds.
Guided tours are given March through October.
