2017 Map of Round Butte Dam

About this map

Lake Billy Chinook dominates this central Oregon landscape, marking the dramatic confluence where the Metolius River, Deschutes River, and Crooked River meet. Controlled by the Round Butte Dam at the head of Lake Simtustus, these deep canyon systems define the local geography, isolating prominent landforms like The Island and The Peninsula. This 2017 survey documents the area within the Crooked River National Grassland, showing the transition from the high Metolius Bench and Lower Desert down into the sheer walls of the Crooked River Gorge and Metolius Canyon. The map reveals a network of remote access roads such as SW Yucca Flats Ln and Jackson Trl, alongside vital infrastructure like the Lake Billy Chinook State Airport, which serves this recreationally significant and geologically complex river system.
