Ruby Lake National Wildlife Refuge

The Ruby Lake National Wildlife Refuge is located in southwestern Elko County and adjacent northwestern White Pine County in the remote Great Basin area of the northeastern section of the state of Nevada in the Western United States. Established in 1938, near the end of the Great Depression of the 1930s, under the presidential administration of 32nd President Franklin D. Roosevelt, as of 2023 it encompasses 39,928 acres (161.58 km2) of wetlands in Ruby Valley, just east of the Ruby Mountains and just south of Harrison Pass. It is 16 miles (26 km) long, up to 3 miles (4.8 km) in width, and lies at an elevation of 6,000 feet (1,800 m). Once the bed of an ancient 200-foot (61 m) deep lake, it is now a network of spring-fed marshes and shallow ponds serving as a habitat for hundreds of species of native and migratory birds and mammals.
