The Dales Dam is 192 miles upstream from the mouth of the Columbia River, two miles east of the city of The Dalles, Oregon. The dam extends 1.5 miles from the Oregon shore to the navigation lock on the Washington shore. The project consists of a navigation lock, spillway, powerhouse and fish passage facilities. Various recreational facilities are provided along Lake Celilo, the 24-mile long lake behind the dam. There is a visitor center available focusing on the project and the region. Then a small brightly painted train takes visitors from the visitor center to the fish ladder and powerhouse for a guided tour. Hydropower exhibits in the powerhouse explain the operation of the dam.
