Chief Joseph Dam

Chief Joseph Dam extends across the Columbia River as a massive concrete structure for power generation. The facility operates with 27 Francis turbines designed to convert water flow into electricity.

Construction of the main structure began in 1949 and was completed in 1955. Full operational capacity was achieved in 1979 when all systems became functional.

The dam is named after a Nez Perce leader who spent his final years living near this region. The name reflects the indigenous history of the area.

The best time to visit is during warmer months when water levels are most stable and accessible. The dam and surrounding area can be easily observed from nearby viewing points along the shore.

The reservoir created by the structure stretches far upstream and becomes a major recreation area in an otherwise dry landscape. The lake supports fishing, boating, and wildlife viewing throughout the year.
