About this map

Round Butte Dam stands as the central engineering marvel of this mid-1980s landscape, where the confluence of the Deschutes River, Metolius River, and Crooked River forms the deep, multi-pronged waters of Lake Billy Chinook. The topography is defined by dramatic plateaus and canyons, including the massive landform known as The Island and the broad agricultural stretches of Metolius Bench and Canadian Bench.

Evidence of historical settlement and land use is found at Grandview (Site) and along the Warm Springs Indian Reservation Boundary to the west. Recreation and utility meet here, as The Cove Palisades State Park borders the reservoir while industrial components like the Powerhouse, Sub Sta, and various Borrow Pits support the dam's operations. This survey preserves the spatial relationship between the river canyons and the higher desert plains before modern development further altered the terrain.
