Lyons Ferry State Park is a public recreation area located near the confluence of the Snake and Palouse rivers, seven miles (11 km) northwest of Starbuck, Washington. The state park is on Route 261 abreast of Lake Herbert G. West, a reservoir on the Snake River created with the construction in the 1960s of the Lower Monumental Dam some 17 miles (27 km) downstream. The park offers facilities for boating, fishing, and swimming. The area is managed cooperatively by the Washington State Parks and Recreation Commission and the U.S. Army Corps of Engineers, which operates the Lyons Ferry Marina.
