The Klamath Basin National Wildlife Refuge Complex is a wildlife preserve operated by the United States Fish and Wildlife Service in the Klamath Basin of southern Oregon and northern California near Klamath Falls, Oregon. It consists of Bear Valley, Klamath Marsh and Upper Klamath National Wildlife Refuge (NWR) in southern Oregon and Lower Klamath, Tule Lake, and Clear Lake NWR in northern California.
Lower Klamath NWR, established in 1908, was the first waterfowl refuge in the United States. Consisting of 46,900 acre (190 km2), it includes shallow freshwater marshes, open water, grassy uplands, and croplands that are intensively managed to provide feeding, resting, nesting, and brood rearing habitat for waterfowl and other water birds.
Clear Lake NWR, established in 1911, has an area of 46,460 acres (188.0 km2). About 20,000 acres (81 km2) is open water. The balance is the surrounding upland habitat of bunchgrass, low sagebrush, and juniper.
Upper Klamath NWR, established in 1928, is composed of 15,000 acres (61 km2) of mostly freshwater marsh and open water.
Tule Lake NWR, established in 1928, encompasses 39,116 acres (158.30 km2) of mostly open water and croplands.
Klamath Marsh NWR, established in 1958, consists of 40,646 acres (164.49 km2) of freshwater marsh and adjacent meadows.
Bear Valley NWR, established in 1978, protects a vital night roost site for wintering bald eagles. It consists of 4,200 acres (17 km2) of largely old growth ponderosa pine, incense-cedar, white fir and Douglas-fir forest.
Historically, the Klamath Basin was dominated by approximately 185,000 acres (749 km2) of shallow lakes and freshwater marshes. These extensive wetlands attracted peak fall concentrations of over 6 million waterfowl and supported abundant populations of other water birds including American white pelican, double-crested cormorant, and several heron species.
In 1905, the U.S. Bureau of Reclamation initiated the Klamath Reclamation Project to convert the lakes and marshes of the Lower Klamath Lake and Tule Lake areas to agricultural lands. As these wetlands receded, the reclaimed lands were opened to agricultural development and settlement. Today, less than 25% of the historic wetlands remain.
To conserve much of the Basin's remaining wetland habitat, the six National Wildlife Refuges have been established. The U.S. Fish and Wildlife Service manages these Refuges to enhance wildlife and benefit the American people. Agricultural and water programs are coordinated under an agreement between the Fish and Wildlife Service and the Bureau of Reclamation.
Klamath Basin Refuges consist of a variety of habitats including freshwater marshes, open water, grassy meadows, coniferous forests, sagebrush and juniper grasslands, agricultural lands, and rocky cliffs and slopes. These habitats support diverse and abundant populations of resident and migratory wildlife with 433 species having been observed on or near the Refuges. In addition, each year the Refuges serve as a migratory stopover for about three-quarters of the Pacific Flyway waterfowl, with peak fall concentrations of over 1 million birds. The Klamath Refuge has been described as "the heartbeat of the Pacific Flyway". [1]
Upper Klamath Lake is a large, shallow freshwater lake east of the Cascade Range in south-central Oregon in the United States. The largest body of fresh water by surface area in Oregon, it is approximately 25 miles (40 km) long and 8 miles (13 km) wide and extends northwest from the city of Klamath Falls. It sits at an average elevation of 4,140 feet (1,260 m).
The Shiawassee National Wildlife Refuge is a 9,870.35 acres (39.9439 km2) National Wildlife Refuge in Saginaw County managed by the United States Fish and Wildlife Service. It is located in the central portion of the lower peninsula of the U.S. state of Michigan, approximately 25 miles (40 km) south of the Saginaw Bay in Lake Huron and five miles (8 km) south of the city of Saginaw in the county's Spaulding and James townships. It was established in 1953 to provide habitat for migratory waterfowl.
The Klamath Project is a water-management project developed by the United States Bureau of Reclamation to supply farmers with irrigation water and farmland in the Klamath Basin. The project also supplies water to the Tule Lake National Wildlife Refuge, and the Lower Klamath National Wildlife Refuge. The project was one of the first to be developed by the Reclamation Service, which later became the Bureau of Reclamation.
The Lower Klamath National Wildlife Refuge is a National Wildlife Refuge of the United States on the border between California and Oregon. It is operated by the United States Fish and Wildlife Service. The refuge was designated a National Historic Landmark on October 16, 1965.
The Tule Lake National Wildlife Refuge is a National Wildlife Refuge of the United States in northern California near the Oregon border. It covers 39,116 acres (15,830 ha) in the Tule Lake basin. It is part of the Klamath Basin National Wildlife Refuge Complex, and is a crucial part of the Pacific Flyway corridor for migratory birds.
Ankeny National Wildlife Refuge is located in the fertile Willamette Valley of northwestern Oregon, 12 miles (19 km) south of Salem. The valley was once a rich mix of wildlife habitats. Valley wetlands were once extensive, with meandering stream channels and vast seasonal marshes. Today, the valley is a mix of farmland and growing cities, with few areas remaining for wildlife.
The Atlantic Flyway is a major north-south flyway for migratory birds in North America. The route generally starts in Greenland, then follows the Atlantic coast of Canada, then south down the Atlantic Coast of the United States to the tropical areas of South America and the Caribbean. Every year, migratory birds travel up and down this route following food sources, heading to breeding grounds, or traveling to overwintering sites.
The Klamath Basin is the region in the U.S. states of Oregon and California drained by the Klamath River. It contains most of Klamath County and parts of Lake and Jackson counties in Oregon, and parts of Del Norte, Humboldt, Modoc, Siskiyou, and Trinity counties in California. The 15,751-square-mile (40,790 km2) drainage basin is 35% in Oregon and 65% in California. In Oregon, the watershed typically lies east of the Cascade Range, while California contains most of the river's segment that passes through the mountains. In the Oregon-far northern California segment of the river, the watershed is semi-desert at lower elevations and dry alpine in the upper elevations. In the western part of the basin, in California, however, the climate is more of temperate rainforest, and the Trinity River watershed consists of a more typical alpine climate.
The Turnbull National Wildlife Refuge is located six miles (10 km) south of Cheney, Washington, on the eastern edge of the Columbia Basin in Spokane County in northeastern Washington. Turnbull NWR encompasses more than 23,000 acres (9,300 ha) of the Channeled Scablands. The ecosystem that predominates the refuge is unique within the National Wildlife Refuge System and has characteristics that distinguish it from natural reserves worldwide. The combination of basalt outcrops, channeled canyons, and ponderosa pine forests infused in a diverse landscape of over 130 marshes, wetlands, and lakes creates an environment of aesthetic beauty as well as high quality wildlife habitat. The refuge is named for Cyrus Turnbull who lived on the site in the 1880s.
The Eastern Cascades Slopes and Foothills ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) in the U.S. states of Oregon, Washington, and California. In the rain shadow of the Cascade Range, the eastern side of the mountains experiences greater temperature extremes and receives less precipitation than the west side. Open forests of ponderosa pine and some lodgepole pine distinguish this region from the Cascades ecoregion, where hemlock and fir forests are more common, and from the lower, drier ecoregions to the east, where shrubs and grasslands are predominant. The vegetation is adapted to the prevailing dry, continental climate and frequent wildfire. Volcanic cones and buttes are common in much of the region.
Lacassine National Wildlife Refuge is located in Cameron and Evangeline Parishes in southwestern Louisiana, was established in 1937 by Executive Order No. 7780 as "a refuge and breeding ground for migratory birds and other wildlife." The refuge is nearly 35,000 acres (140 km2) in size, including 653 acres (2.64 km2) leased from the Cameron Parish School Board. The Evangeline Parish unit is called Duralde Prairie and is currently being developed. It is located south of the city of Eunice.
Lake Ophelia National Wildlife Refuge was established in 1988 to protect the Mississippi/Red River floodplain ecosystem. The refuge is located in Avoyelles Parish, Louisiana, east central Louisiana. The refuge is named for its most prominent water body, the 350-acre (1.4 km2) Lake Ophelia that was at one time a channel of the nearby Red River of the South.
The San Luis National Wildlife Refuge Complex is located in the northern San Joaquin Valley, within Merced County and Stanislaus County of California. The complex, with four federal National Wildlife Refuges, is managed by the U.S Fish & Wildlife Service.
The Sonny Bono Salton Sea National Wildlife Refuge is located in the Imperial Valley of California, 40 miles (64 km) north of the Mexican border. Situated at the southern end of the Salton Sea, the refuge protects one of the most important nesting sites and stopovers along the Pacific Flyway. Despite its location in the Colorado Desert, a subdivision of the larger Sonoran Desert, the refuge contains marine, freshwater, wetland, and agricultural habitats which provide sanctuary for hundreds of birds and wetland species, including several that have been listed as endangered or sensitive by the U.S. Fish and Wildlife Service.
Clear Lake National Wildlife Refuge is a National Wildlife Refuge of the United States in northeastern California. It includes about 20,000 acres (81 km2) of open water surrounded by over 26,000 acres (110 km2) of upland bunchgrass, low sagebrush, and juniper habitat. small, rocky islands in the wetlands provide breeding sites for American white pelicans, double-crested cormorants, and other colony-nesting birds.
The Umatilla National Wildlife Refuge is located on and around the Columbia River about 15 miles (24 km) northwest of Hermiston, Oregon and includes 8,907 acres (3,605 ha) in Oregon, and 14,876 acres (6,020 ha) in Washington. It was established in 1969 to help mitigate habitat lose due to the flooding that occurred following the construction of the John Day Dam. The refuge is popular with birdwatchers and wildlife enthusiasts.
Cold Springs National Wildlife Refuge is a 3,117-acre (12.61 km2) National Wildlife Refuge located 7 miles (10 km) northeast of Hermiston and 3 miles (5 km) south of the Columbia River in Umatilla County, Oregon; The refuge was established in 1909 as a preserve and breeding ground for native birds. It consists of diverse wetland habitats surrounded by upland habitat of big sagebrush and native steppe grasses. A riparian component of willow and cottonwood provides refuge for birds, mammals, and other animals.
Modoc National Wildlife Refuge is a National Wildlife Refuge of the United States located in northeastern California. It is next to the South Fork of the Pit River in Modoc County, southeast of Alturas.
The Merced National Wildlife Refuge encompasses 10,262 acres (41.53 km2) of wetlands, native grasslands, vernal pools, and riparian areas in California. It was established in 1951 under the Lea Act to attract wintering waterfowl from adjacent farmland where their foraging was causing crop damage. In the last few decades, changes in agricultural practices and refuge management have reduced these wildlife/crop issues.
The Summer Lake Wildlife Area is a 29.6-square-mile (77 km2) wildlife refuge located on the northwestern edge of the Great Basin drainage in south-central Oregon. It is administered by the Oregon Department of Fish and Wildlife. The refuge is an important stop for waterfowl traveling along the Pacific Flyway during their spring and fall migrations. The Summer Lake Wildlife Area also provides habitat for shorebirds and other bird species as well as wide variety of mammals and several fish species. The Ana River supplies the water for the refuge wetlands.
