Topaz Lake, Reservoir at California-Nevada border, United States.
Topaz Lake extends 3.5 miles in length and 1.5 miles in width, covering 2,410 acres with an average depth of 52.3 feet.
The initial dam construction began in 1922 with a capacity of 45,000 acre-feet, later expanded through a new levee built in 1937.
The lake holds significance as part of Jedediah Smith's first journey across the Sierra Nevada in 1827 during early American exploration.
The Walker River Irrigation District manages the reservoir, which offers year-round fishing with regular trout stocking by Nevada and California wildlife departments.
The reservoir formed by diverting waters from the West Walker River into a basin that previously contained a smaller natural lake.
