RUBY LAKE National Wildlife Refuge

Not a lake, but rather a vast open-water marsh, the 37,632-acre refuge includes 17,000 acres of wetlands with bulrush and grass-covered islands. Like neighboring Fish Springs National Wildlife Refuge, some 100 miles to the east in Utah, Ruby Lake NWR is a Great Basin oasis that depends on a fresh supply of water. The water comes from over 150 springs at the base of the Ruby Mountain range on the western edge of the refuge. The watershed is closed, so all water entering the marsh is clean and pure. The water that gushes from a cave behind refuge headquarters is so clean that it needs no treatment before being piped to the office and residences.

Ruby Valley is actually a basin within the basin that once contained 300,000-acre and 200-foot deep Franklin Lake. Ruby Lake is one of two wetland remnants of that ancient lake. It is said that early settlers misnamed the valley in the notion that red garnet stones they found scattered about were rubies.

By Executive Order in 1938, President Franklin D. Roosevelt established the Ruby Lake NWR. Twenty percent of the refuge was apportioned from public land, and the remainder was purchased with the Migratory Bird Conservation Fund for slightly over $200,000 (about $7 per acre). The refuge habitat was recognized for its importance for ducks, geese, grouse, sandhill cranes, and shorebirds.

At one time, wildlife at Ruby Lake National Wildlife Refuge in northeast Nevada was anything but a first priority. The remote refuge was a recreational wonderland to about 30,000 boaters a year, and water skiers were often a more common site across the open water of the desert marsh than the waterfowl it was established to protect. In fact at one point a section of the marsh was pumped dry to maintain sufficient depths for boating in another section.

But all that has changed. Now the motorboat season and engine size are strictly regulated--the result of a lawsuit and a U.S. District Court ruling which prioritized the interests of wildlife over the interests of boaters.

Waterfowl & Wildlife

Blue Heron

It should be no surprise that the Ruby Lake National Wildlife Refuge is recognized by Nevada’s Lahontan Audubon Society as an Important Bird Area.

Of special interest are the canvasback and redhead nesting areas in the prolific bulrush of the South Marsh, a natural depression at the south end of the refuge. This area has the highest canvasback nesting density of anywhere in North America. During the years of flood and drought extremes, breeding birds were forced to nest elsewhere and managers were concerned about their success with limited wetlands.

Among the other waterfowl species that nest in the marsh are Canada geese, trumpeter swans, gadwalls, lesser scaups, and cinnamon and blue-winged teals. Migrating waterfowl stop at the refuge beginning in mid-August, but most are gone by October because, unlike Fish Springs' marshes, most of Ruby Lake's marshes freeze during the winter.

Migration appears to be cause for a decline in resident trumpeter swan populations. Established in the 1950s with transplants from Montana's Red Rock Lakes NWR, the birds are now apparently joining flocks that travel to nesting areas farther north.

Western, eared, and pied-bill grebes are refuge nesters, as are great blue herons, American bitterns, and black-crowned night herons. The refuge's first little blue heron was spotted in 1993.

Sandhill Cranes

Fluxuating water levels limit the number of shorebirds. Impressive numbers arrive only when melting snows flood the shallow playas. Because they depend less on shallow water for feeding, long-billed curlews, killdeer, and common snipe are common. Abundant prey, supported by both marsh and uplands, attract red-tailed hawks, golden eagles, great horned owls, and prairie falcons.

Despite the harsh winters, some 60 bird species are tallied in the Christmas bird counts. Resident species include the rather scarce sage grouse, horned larks, black- billed magpies, and bushtits. A total of 207 bird species are recorded on the year-round refuge bird list.

Mule deer are the most common big mammals. Pronghorn antelope, introduced into the valley by the state of Nevada in 1988, are seen only occasionally. The abundance of coyotes is probably due to plentiful prey, including blacktail jackrabbits, which are hunted by the raptors as well.

Coyote predation may be the reason that sandhill cranes do not fledge their colts at Ruby Lake. In 1992, 17 juvenile birds never made it to flight stage. One colt was fledged in 1994 for the first time in 9 years. The parent birds maintained a territory close to refuge headquarters, which may have afforded protection from predators.

Fishing

Large-mouth bass were introduced in the South Marsh in 1932. By the 1940s, Ruby Lake NWR was recognized as one of the top 10 bass-fishing locations in the United States. The bass flourished while the relict dace, a fish native to northeast Nevada and once abundant in the marsh, declined precipitously. Now the bass have declined as well.

A fisherman from Elko, Nevada, blames the loss of "fabulous" fishing on wildlife biologists who wanted to get rid of the fish because, as he said, "They don't consider fish to be wildlife."

Overfishing, however, was the main culprit, says former refuge manager Dan Pennington, exacerbated by several severe droughts and cold winters. More rain and changes in the state fishing regulations to facilitate maturation of bass are reported to be helping to bring the population back.

Anglers used to account for more than 90 percent of the 50,000 annual refuge visitors, and they still account for 70 percent of the current 10,000 annual visitors. Wildlife observation and photography draws the second biggest group. Selected dike roads are open for observation, and a county road offer over 15 miles of refuge viewing. Seasonal hunting is permitted for only migratory birds including ducks, geese, coots, common moorhens, and common snipe.

Forging a Better Refuge

To establish more quality waterfowl habitat, the refuge has embarked on the first phase of an improvement project for one of several areas that were diked by the post-World War II Civilian Conservation Corps.

The East Marsh was divided by a new dike for better water control and reconfigured to create island and open-water areas.

Besides limited water-level control and prescribed burns, the other principal management tool employed at Ruby Lake is grazing by domestic animals.
