Bridgeport State Park is a 748-acre camping park with 7,500 feet of freshwater shoreline on Rufus Woods Lake. Set directly behind Chief Joseph Dam, this lake is actually a segment of the Columbia River. The park provides 18 acres of lawn and some shade in the midst of a desert terrain. “Haystacks,” unusual volcanic formations resembling their name, are the park’s most striking feature. The park was created as part of a cooperative agreement between Washington State Parks and the U.S. Army Corps of Engineers. The Corps is involved in park-building because of an operating agreement for dams which requires the corps to rebuild recreation areas.
