2018 Map of Silva Flat Reservoir

About this map

Hayden Hill dominates the northern landscape of this Lassen County interior, marking a high point in a region defined by extensive water management systems. The 2018 survey reveals a network of high-altitude basins and reservoirs, including the central Silva Flat Reservoir and Juniper Lake. The terrain transitions from the timbered heights of Modoc National Forest and Lassen National Forest into open flats like Antelope Flat and Sage Hen Flat. This complex system of small-scale impoundments, such as Spaulding Reservoir and Deadhorse Reservoir, indicates the critical role of water storage for local ranching and forestry operations. Prominent peaks such as Indian Mtn and Lost Valley Mtn overlook a series of valleys and canyons, including Coyote Canyon and Corral Valley, which are accessed by a few primary routes like Hayden Hill Rd.
