The Cove Palisades State Park is a state park in eastern Jefferson County, Oregon, near Culver and Madras in the central part of the state, and is administered by the Oregon Parks and Recreation Department. It is located on the waters and surrounding lands of Lake Billy Chinook, an impoundment of the Crooked, Deschutes, and Metolius Rivers.
The park offers two full-service campgrounds, rental cabins, food and supplies for sale, marina access to Lake Billy Chinook with watercraft rentals, fishing, day use and picnic areas, and hiking trails. The park also offers historical interpretation, including of the Crooked River Petroglyph
in the park.
Lake Billy Chinook
Lake Billy Chinook lies in canyons carved by the three rivers into earth held in place by basaltic caprock. Construction of the Round Butte Dam
was completed in 1964 across the Deschutes River. Operated by Portland General Electric
(PGE), and jointly owned by PGE and the Confederated Tribes of Warm Springs
, the dam and lake primarily provide electric generation. The Confederated Tribes named the lake in honor of Billy Chinook, a member of the Wasco
tribe who acted as a guide for John C. Frémont
in the region of the lake. The lake extends beyond the boundaries of The Cove Palisades State Park.
Although fish passage facilities were installed at Round Butte Dam, anadromous fish, such as Chinook salmon failed to be able to pass the dam. As a result, since the dam's completion migratory fish have blocked from once-abundant spawning grounds on the upper Deschutes River and tributaries such as the Crooked River.
Research natural area
Embraced by the Crooked River and Deschutes River Arms of Lake Billy Chinook, the isolated, 200-acre plateau called The Island (actually a peninsula, but with the appearance of an island due to its isolation by high, sheer cliffs) was designated a research natural area
in 1986. The Island supports one of the last relatively pristine remnants of pre-settlement ecology in the western United States
, and was closed to most public access in 1997.
