Geology, Fire and Wildlife
Topaz Lake is an artificial reservoir located on the California-Nevada border, about 75 miles south of Reno. The lake was formed by diverting waters from the West Walker River into a nearby basin that had previously contained a smaller, natural lake.
The initial construction took place in 1922, resulting in a reservoir with a capacity of 45,000 acre-feet. In 1937 a new levee raised the capacity to its current 59,440 acre-feet. Topaz Lake is popular for boaters, water-skiers, campers, and fishermen.
Fishing season runs from January 1 to September 30, and the lake is stocked with trout by the Nevada Department of Wildlife and the California Department of Fish and Game.
Monitor Pass (highway 89) is located a few miles south of the Lake. Monitor Pass, which climbs to 8,314 feet, is subject to winter closure due to snow accumulation.
