2011 Map of Jacobs Reservoir

About this map

Guano Creek winds through the high desert landscape of Lake County, Oregon, defining a terrain dominated by ephemeral water sources and expansive flats. This area of the Great Basin is characterized by its network of shallow lakes, reservoirs, and waterholes that speak to the region's ranching and land management history. Central features like Jacobs Reservoir and O'Keefe Reservoir sit alongside family-named or utilitarian landmarks such as Wire Corral Flat and Squib Waterhole. The map illustrates a system of drainage and storage, where Warner Creek and various catchments like Handle Reservoir and June Reservoir provide critical water in an otherwise arid environment. From the elevation of Cat Butte to the broad expanse of Big Flat, the topography is shaped by internal drainage basins typical of this part of the Pacific Northwest.
