2015 Map of Warm Springs Mountain

About this map

Castaic Lake dominates this portion of the Angeles National Forest, illustrating the critical role of water infrastructure in Southern California during the mid-2010s. The map details the complex geography of the region, where the Los Angeles Aqueduct and the Castaic Tunnel Number One interface with the natural terrain. The landscape is defined by deep drainage systems such as Elizabeth Lake Canyon and San Francisquito Canyon, which flank the high peaks of Warm Springs Mtn and Red Mtn. For those tracing local development, the presence of Castaic Valley and the Castaic Lagoon south of the primary reservoir shows the managed flow of the state's water resources. Further east, smaller features like Drinkwater Reservoir and the naming of areas such as Drinkwater Flat reflect historical family names and earlier ranching or homesteading eras.
