Ruby Valley, Nevada
A Refuge for Nesting and Migrating Waterfowl and Other Wildlife
Ruby Lake National Wildlife Refuge was established in 1938. It encompasses 37,632 acres at the south end of Ruby Valley. This land was once covered by a 200 foot deep, 300,800 acre lake known as Franklin Lake. Today 12,000 acres of marsh remain on the refuge. Just north of the refuge, a 15,000 acre seasonal wetland is now referred to as Franklin Lake.
The refuge, at an elevation of 6,000 feet, consists of an extensive bulrush marsh interspersed with pockets of open water. Fish are abundant. Islands scattered throughout provide good nesting habitat for many bird species.
Over 200 springs flow into the marsh along its west border creating riparian habitat which is used by many songbirds, snipe, rail and small mammals. They also provide a water source for larger mammals. With slight increases in elevation, wet meadows gradate into grasslands and sagebrush-rabbitbrush habitat.
Pinon Pines and juniper cover the slopes of the Ruby Mountains that rise to 11,000 feet along the west side of the refuge. Canyons provide habitat for a variety of wildlife. Rock cliffs provide raptors with nesting and perching sites. A mountainside of dead trees, home for cavity dwelling birds, was the result of a 1979 fire.
Viewing wildlife is best done during morning and evening hours. Binoculars or a spotting scope greatly assist in identifying wildlife and observing their behavior. Best wildlife viewing from a car can be done by taking the Bressman Cabin Loop passing Unit 10, the North and East Sumps, and Unit 13 and/or by taking the Brown Dike-Short Dike Loop around Unit 21. For a unique opportunity to see the marsh wildlife up-close, the South Sump is open during part of the year for canoeing and electric motors.
Eight species of fish are present in the refuge waters. The relict dace is the only species that is native to the marsh. This species is present in only a few other basins in northeastern Nevada. Largemouth black bass were stocked in 1932 or 1933 and have successfully reproduced. Rainbow, Eastern brook and brown trout are stocked annually with occasional stocking of cutthroat and tiger trout. A small population of Lahontan speckle dace has maintained itself from a 1950 stocking. The following names are in accordance with the checklist presented in "Fishes and Fisheries of Nevada" by LaRivers (1962).
The following symbols are used to indicate in which habitats each wildlife species would most likely be found. It is important to remember that use of an area depends on the season and an animal's activity.
