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 (1882-1945, served 1933-1945), as of 2023 it encompasses 39928 acre of wetlands in Ruby Valley, just east of the Ruby Mountains and just south of Harrison Pass. It is 16 mi long, up to 3 mi in width, and lies at an elevation of 6000 ft. Once the bed of an ancient 200 ft 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. The Refuge is administered by the U.S. Fish and Wildlife Service, a longtime agency unit of the United States Department of the Interior. A Visitor's Center (located at 40.20217°N, -115.49283°W) and auto-tour route allow for discreet viewing of waterfowl.

Ruby Marsh

Ruby Marsh is a wetlands area within the national refuge, which serves as a nesting area for "the greater sandhill crane and trumpeter swan". In 1972, Ruby Marsh, which is located within the Ruby Lake National Wildlife Refuge, was designated as a National Natural Landmark by the National Park Service of the United States Department of the Interior.
