2020 Map of May Lake

About this map

South Warner Rim dominates the western topography of this high desert landscape, dropping sharply into the wide expanse of the Warner Valley. This portion of Lake County is defined by its water management systems, characterized by numbered catchments including Cork Reservoir Number Seven, Habillu Reservoir Number Four, and Expand Reservoir Number Thirty. These man-made features, alongside named natural points like May Lake and Lucky Reservoir, reflect the critical role of water storage in supporting local ranching and livestock operations. The presence of specific watering sites such as Cattle Guard Spring, Surveyor Spring, and Y Spring further highlights the utilitarian nature of the terrain. Connectivity across this sparsely populated region is maintained by a network of rural routes, including Twentymile Rd and Cahill Ln, which traverse the flats and skirt the base of prominent rises like Mosquito Mountain.
