2021 Map of Dorris Reservoir

About this map

Dorris Reservoir anchors this high-desert water management landscape in the shadows of the Warner Mountains. The terrain is defined by a sophisticated network of catchment and storage, where numerous smaller basins such as Dannhauser Reservoir, Payne Reservoir, and French Reservoir dot the valley floor. These reservoirs are fed by a series of seasonal drainages, including Pine Cr and Fitzhugh Cr, which descend from the more dramatic topography of the eastern peaks. To the northeast, the land rises into the complex drainage systems of Renfro Canyon and White Horse Canyon. This USGS study reveals the contemporary infrastructure of Modoc County, showcasing how modern ranching and conservation efforts rely on these dispersed water sources. The map also delineates the extensive rural road network, including Pine Creek Blvd and Parker Creek Rd, which provide access across the township and range grids.
