2024 Map of Round Butte Dam

About this map

Lake Simtustus occupies a critical portion of the Deschutes River drainage, as documented in this contemporary 2024 topographic study. This reservoir, created by the Pelton Dam, sits just downstream from the confluence of the Crooked, Deschutes, and Metolius rivers. The geography here is defined by dramatic canyon walls and high desert plateaus typical of Jefferson County, Oregon. While the map is a modern 2024 edition, it serves as a precise record of the current shoreline and the controlled water levels of this significant hydroelectric and recreational impoundment. Historians and researchers can use this data to understand the modern management of the central Oregon river systems and the resulting landscape changes since the early twentieth-century damming projects.
