2018 Map of Drinkwater Lake

About this map

The Granite Mountains dominate the central terrain of this high desert landscape, providing a dramatic backdrop to the arid reaches of the Mojave Desert. This 2018 survey by the U.S. Geological Survey captures a region defined by its vital water sources and passage points. Critical hydrologic features such as Drinkwater Spring and Devouge Spring are meticulously recorded, alongside the seasonal Drinkwater Lake at the northern edge of the quadrangle. Transport through this area is anchored by Fort Irwin Rd, which winds through Granite Pass, a natural corridor between the desert flats and the surrounding peaks. The map provides a detailed view of the Public Land Survey System (PLSS) grid across townships T16N R3E and T15N R4E, offering a clear layout of the township and range divisions that define land management in this portion of San Bernardino County.
