U.S. Fish & Wildlife Service Deer Flat National Wildlife Refuge Deer Flat National Wildlife Refuge provides a watery oasis for resident and migratory wildlife, including spectacular concentrations of waterfowl. About the Refuge Deer Flat National Wildlife Refuge has two units, Lake Lowell and the Snake River Islands. The Lake Lowell Unit encompasses 10,619 acres, including the almost 9,000-acre Lake Lowell and surrounding lands. The Snake River Islands Unit contains about 1,200 acres on 104 islands. These islands are distributed along 113 river miles, from the Canyon-Ada County Line in Idaho to Farewell Bend in Oregon. Diverse Habitats The Refuge provides a mix of wildlife habitats, from the open waters and wetland edges of Lake Lowell to the sagebrush uplands around the lake and the grasslands and riparian forests on the Snake River islands. The variety of habitats makes Deer Flat NWR an important breeding area for resident and migratory birds and other wildlife. The Refuge is also a significant resting and wintering area for birds migrating along the Pacific Flyway, including spectacular concentrations of mallards and Canada geese. A System of Refuges Snow and Ross’s geese USFWS 2 Deer Flat NWR is one of the oldest refuges in the National Wildlife Refuge System, which now includes over 560 refuges. Managed by the U.S. Fish and Wildlife Service, the System preserves a network of lands and waters set aside for the conservation and management of the nation’s fish, wildlife, and plant resources for the benefit of present and future generations. This blue goose, designed by J.N. “Ding” Darling, has become the symbol of the National Wildlife Refuge System. 3 A Brief History Early Settlers F.C. Horn/Bureau of Reclamation Creating Lake Lowell Before settlement, the land that would become Deer Flat NWR was a low-lying area with many springs. In winter, herds of deer and elk came from the mountains to eat the abundant grasses. Early settlers observing these herds dubbed the area Deer Flat. The reservoir was completed in 1908 at a cost of $2,500,000. Unfortunately, local landowners greeted it with outrage rather than cheers because most of the water first used to fill the reservoir either evaporated or leaked out. Fortunately, the reservoir soon began to hold water. Needing water to irrigate crops, settlers initially restricted their settlements to land near rivers. In the early 1900s, they began lobbying and raising money for a reservoir. The Bureau of Reclamation began work on the Deer Flat Reservoir in 1906. In 1945, Deer Flat Reservoir was renamed Lake Lowell in honor of James H. Lowell, who had spearheaded efforts to establish the reservoir in his position as president of the local water users’ association. Lake Lowell is now one of the largest off-stream reservoirs in the American West, with the capacity to irrigate over 200,000 acres of land. Between 1906 and 1908, two large and two small earthen embankments, or dams, were built to contain the reservoir. The Upper Dam was constructed using a smallgauge train to haul, dump, and compact the material. Horse teams were used on the Lower Dam. Workers also constructed a diversion dam on the Boise River and enlarged the New York Canal, which brings water from the Boise River to the reservoir. Establishment of the Refuge Left: Deer Flat steam shovel Below: Horse teams compacting the dam F.C. Horn/Bureau of Reclamation 4 With the reservoir completed, President Theodore Roosevelt realized that a nearly 9,000-acre lake in an arid region would be an oasis for wildlife, so he created Deer Flat NWR in 1909, just three days after water started flowing into the reservoir through the New York Canal. The Refuge remained unstaffed until 1937, when 36 islands in the Snake River were added to protect a riparian corridor for wildlife. Through land purchases, donations, and other land-acquisition methods, the Refuge eventually expanded to about 11,800 acres. 5 Seasons of Wildlife A Brief History continued Spring Bureau of Reclamation In the 1930s, a Civilian Conservation Corps camp was established at the Lower Dam and grew to over 100 corpsmen, who spent many years quarrying lava rock to face Civilian both dams. Crews from the Works Conservation Progress Administration also worked Corps crew working on Refuge projects. Some created on parapet wall nesting islands in the eastern portion of the lake, while others would “line up shoulder to shoulder and walk around the lake pulling or digging up…undesirable plants.” Both of these programs ended with the start of World War II. Refuge Visitor Center built by the Job Corps In the early 1970s, Job Corps students from the nearby center in Marsing, Idaho constructed many of the current Refuge facilities, including the Visitor Center, shop, a residence, and facilities at the Lower Dam Recreation Area. Resident Canada geese set up nesting territories on the Snake River islands in early March, and goslings hatch by mid-April. At the same time, large numbers of white-fronted geese gather on the Snake River below Homedale and Weiser for up to a month before continuing their northward migration. © Dan & Lin Dzurisin Work Crews Canada goose goslings Bald eagles, osprey, and great horned owls nest on both units of the Refuge, with most feeding nestlings by the end of April. Nesting great blue herons, black-crowned night herons, and double-crested cormorants get a slightly later start. They nest in large rookeries on some of the Snake River islands in April, May, and June. Great horned owl USFWS © Matt Knoth 6 7 Seasons of Wildlife continued © Linda Tanner Dancing western grebes Fall In early summer, western and Clark’s grebes can be seen dancing on Lake Lowell in search of a mate, while nesting bald eagles look for food for their young. Visitors can see large numbers of white pelicans on the lake and large broods of Canada geese on pastures and fields adjacent to the Snake River. By late July and early August, mallards and wood ducks begin to congregate on the lake, looking for food in flooded vegetation. As summer progresses and the lake is slowly drawn down for irrigation, large numbers of shorebirds come to feed on the exposed mudflats. Look for dowitchers, sandpipers, godwits, yellowlegs, and plovers. Spotted sandpiper As fall approaches, the number of birds using the Refuge increases. The large exposed mudflats continue drawing vast numbers of shorebirds. Resident flocks of ducks and Canada geese are usually on Lake Lowell by the second week of October. As cold weather drives migrating ducks and geese south, migratory birds join the resident birds at the lake. Some birds pass through, while others spend the winter. By midNovember, the goose population peaks. © Teddy Llovet Summer Canada geese © Ingrid Taylar © Mike Shipman White pelican Flocking geese, ducks, and gulls at Lake Lowell 8 USFWS 9 Managing Habitats Seasons of Wildlife continued © Enrico Mevius Mallard Lake Lowell habitats Wetland Habitats Yellow-headed blackbird © Mark Winchester Addison Mohler/USFWS Canada geese in local croplands Duck populations peak in midDecember. Geese and ducks roost on the lake at night, their activity usually keeping patches of water open all winter. At dawn, they depart in large flocks to feed in the surrounding area. Visitors can see these flights of ducks and geese at dawn or dusk, or view the large flocks of geese that feed on nearby fields during the day. Bald eagles, which move into the area to feed on weak and injured birds, can often be seen around the lake. 10 Bald eagle © Mark Winchester Western grebes in smartweed During spring and summer, water is released from Lake Lowell to irrigate surrounding farm fields. This slow draw-down of the lake exposes mudflats that provide abundant habitat for shorebirds. The lake also produces a bumper crop of aquatic vegetation for birds to feed on, particularly smartweed. In fall, smartweed seeds provide a feast for migratory ducks heading south. The Refuge also has marsh areas where the water is manipulated to provide feeding, nesting, and resting habitat for mallards, sora rails, yellow-headed blackbirds, and other wildlife. Addison Mohler/USFWS The Snake River also provides a winter home for a variety of waterfowl, including goldeneyes, scaup, mergansers, buffleheads, wood ducks, green-winged teals, and a large number of mallards. Wildlife needs a variety of habitats for food, shelter, and raising young. Deer Flat NWR is managed to improve and maintain habitat for wildlife. © Lauren Giebler Winter 11 Managing Habitats continued © Trish Gussler Screech owl in a cavity nest Snake River Islands Uplands Riparian areas near the lake, as well as many of the Refuge islands, contain primarily cottonwood, peachleaf willow, and coyote willow. These areas provide food, nesting sites, and cover from predators for a variety of tree-dependent species. Of the 320 species of Idaho birds, nearly one-third nest in cavities in hollow trees. The 104 islands of the Snake River Islands Unit provide a variety of habitats, including areas dominated by grasses, sagebrush, and trees such as maples, box elders, and cottonwoods. These islands provide ideal nesting habitat for Canada geese, ducks, herons, gulls, cormorants, and various songbirds. To protect nesting birds, the islands are closed to all public entry from February 1 to June 14 for most islands, or June 30 for several heron and gull-nesting islands. Mule deer in sagebrush upland Sagebrush, rabbitbrush, and the bunchgrass Great Basin wild rye dominate the uplands near the lake and on the islands. Large blocks of this native habitat can be visited just west of the Visitor Center and on several of the larger Refuge islands. Addison Mohler/USFWS Riparian Forests Rabbits, gophers, mule deer, and even grasshoppers feed on upland plants and rely on them for nesting sites and cover. Predators such as badgers, foxes, coyotes, red-tailed hawks, or American kestrels may later eat these animals.

Wildlife is generally most active in the mornings and early evenings. Mule deer If driving, your car is an excellent observation and photographic blind. Stay in your car to have better viewing opportunities. If walking, move slowly and quietly to avoid scaring wildlife. The best season for viewing a wide variety of wildlife is from September through December. Addison Mohler/USFWS When to Visit With over 250 bird species and 30 mammal species on the Refuge, the patient observer or photographer has many excellent wildlife viewing opportunities. © Dan & Lin Dzurisin Use binoculars or a spotting scope to view animals up close without disturbing them. Where to Go Look closely at your surroundings for tracks, chewed leaves or branches, and any other evidence that animals have been there before you. Some areas of the Refuge are closed to protect wildlife, so watch for signs and check the map. Learn more about wildlife. A Refuge bird list is available at the Visitor Center. In addition, a good field guide can help you identify the species you see. For an auto tour, drive the 29.5-mile bird tour around Lake Lowell or the 47-mile bird tour that includes the Snake River. Both tours start and end at the east end of the Upper Dam. Written guides for these tours are available at the Visitor Center or on the refuge web site. 14 Those who prefer to walk can visit the short, self-guided Nature Trail at the Visitor Center. For a longer hike, there are several miles of trails that begin near the Visitor Center, near Gotts Point, and at the end of Tio Lane. Please be considerate. Do not approach other wildlife watchers or wildlife too closely. Do not pick up wildlife. While you may think that a young animal has been abandoned, more than likely it has a parent watching anxiously nearby. Gull nesting colony on refuge island USFWS Pets will scare wildlife before you get a chance to see it. Consider leaving pets at home. 15 Enjoying the Refuge The Refuge is open to the public all year during daylight hours only. Please help protect wildlife and their habitats by obeying all regulations.
