The Cove Palisades State Park, State park with three rivers junction in Oregon, US.
The Cove Palisades State Park is a protected area in Oregon featuring Lake Billy Chinook, which formed when three rivers were dammed to create a large reservoir. The landscape includes steep canyon walls, rocky outcrops, and multiple arms of water that reach into narrow valleys.
The area began as a recreational site in the 1940s when the federal government started leasing and acquiring land in the river canyons. The park grew over the following decades as facilities and infrastructure were gradually added to serve visitors.
The landscape here reflects the powerful geological forces that shaped central Oregon, with red and dark rock layers visible throughout the canyons and cliffs. Visitors walking through the area can see how nature carved these deep waterways over thousands of years.
The park operates year-round, though water-based activities and most facilities operate seasonally during warmer months. Visitors should plan their trip around seasonal closures and check conditions before arriving, especially for camping and boat access.
The park includes a constructed wetland that uses cattail plants to filter runoff water before it enters the lake. This engineered system, built to maintain water quality and support fish life, demonstrates how modern conservation works in balance with recreation.
