2014 Map of Topaz Lake

About this map

Topaz Lake straddles the rugged border between Nevada and California, serving as a focal point for this high-desert landscape in the early 21st century. The map details a complex network of water management features, including the Topaz Canal, Wiley Ditch, and Alkali Ditch, which redirect flow from the West Walker River to support the surrounding Antelope Valley. Settlements like Coleville and Topaz are situated along the valley floor, while the terrain rises sharply to the west into the Toiyabe National Forest. High-altitude landmarks such as Leviathan Peak and Monitor Pass define the western reaches, contrasted by the more developed residential grid of Holbrook Junction to the north. This survey captures the vital relationship between the region's steep topography and the irrigation systems that sustain life in the basin.
