Swift Dam, also known as Swift No. 1, is an earth-filled hydroelectric barrier situated on the Lewis River in Washington state, managed by PacifiCorp. Finished in 1958, it lies within Skamania County and forms the Swift Reservoir.
Measuring 2,100 feet in length and rising to a height of 512 feet, the dam impounds a reservoir with a capacity near 755,600 acre-feet. The reservoir spans about 4,620 acres and drains a watershed area of 481 square miles. The associated hydroelectric facility has a generating capacity of 240 megawatts, enhancing PacifiCorp’s renewable energy assets.
