Wanapum Dam is located on the Columbia River, six miles downstream of Vantage, Wash., 18 miles upstream of Priest Rapids Dam and 415 miles above the mouth of the river.

The dam was named Wanapum in honor of the band of Native Americans who live along a stretch of the Columbia River from Vantage south toward Pasco, Wash.

Wanapum Dam was financed by long-term revenue bonds that were retired through the sale of power. No tax money or government appropriations were used for construction of Priest Rapids or Wanapum dams.
