localities along the river in Canyon, Owyhee, Payette, and Washington counties (Idaho) and Malheur and Baker counties (Oregon). There is a visitor center at the Lake Lowell site, which is the hub of activity for visitors and those volunteers who donate their time and services to wildlife conservation projects. Wildlife and Habitat Wildlife has dynamic and unique needs that require a variety of habitats for food, shelter, and raising young. Deer Flat National Wildlife Refuge is managed to improve and maintain wildlife habitat.

ll, just outside Nampa, Idaho. It serves as a resting and wintering area for birds, including mallards and Canada geese, along the Pacific Flyway and was named a "Globally Important Bird Area" by the American Bird Conservancy. The refuge consists of two sections which contains open water, edge wetlands, grasslands and riparian and forest habitats.

States. The Boise Greenbelt is more of a greenway than a green belt since its character is linear. It extends more than 20 miles (32 km) beginning at Lucky Peak Dam in the east to a short distance beyond Eagle Road (Idaho State Highway 55) in the west in Eagle, Idaho. Taking into account both sides of the river and other parallel trails and spurs, the total Greenbelt trail system measures more than 30 miles (48 km). The Greenbelt connects Boise's riverside parks and connects Boise with neighboring municipalities. The majority of the Greenbelt is paved with asphalt or concrete on both sides of the river. However some sections are unpaved and bicycles may be prohibited on some unpaved sections. Where this occurs, bicycles have alternate routes on residential streets or dedicated bike paths. Motorized vehicles are prohibited on all parts of the Greenbelt.

and four navigation dams on its lower section created a shipping channel to Lewiston, Idaho – the furthest inland seaport on the West Coast. While dam construction, commercial fishing and other human activities have greatly reduced anadromous fish populations since the late 19th century, the Snake River watershed is still considered important habitat for these fish. The Snake and its tributary, the Salmon River, host the longest sockeye salmon run in the world, stretching 900 miles (1,400 km) from the Pacific to Redfish Lake in Idaho. Since the 1950s, public agencies, tribal governments and private utilities have invested heavily in fishery restoration and hatchery programs, with limited success.

As gold mining declined in the late 19th century, the wheat industry boomed in the Palouse of southeast Washington. By the 1870s, the Oregon Steam Navigation Company was operating seven steamboats transporting grain from the Snake River to lower Columbia River ports. These were the Harvest Queen, John Gates, Spokane, Annie Faxon, Mountain Queen, R.R. Thompson, and Wide West. In the 1890s, a huge copper deposit was discovered at Eureka Bar in Hells Canyon. Several ships transported ore from there to Lewiston, including Imnaha, Mountain Gem, and Norma. In 1893 the Annie Faxon suffered a boiler explosion and sank on the Snake below Lewiston, killing five people. Starting in the 1880s, the Army Corps began dredging the Snake River below Lewiston to maintain a 5-foot (1.5 m) deep navigation channel. River traffic declined rapidly once railroads arrived. By 1899, the Union Pacific line along the south bank of the Snake River had reached Riparia, Washington. It then joined forces with the Northern Pacific Railroad, which was building a line along the north bank, to build the shared Camas Prairie Railroad the rest of the way to Lewiston, which it reached in 1908. The Open River Transportation Company, which operated steamboats between Lewiston and Celilo Falls on the Columbia, went bankrupt in 1912. The 1915 completion of the Celilo Canal made it much easier for boats from the upper Columbia and Snake to reach Portland, and the Columbia River Transportation Company began operating a water route between Lewiston and Portland. Still, steamboats were unable to compete with railroads on speed and efficiency. The last steamboat on the lower Snake ran in 1920. Once the railroads monopolized grain shipments, they raised shipping rates, to farmers' consternation. In 1934, political activist Herbert G. West organized the Inland Empire Waterways Association (IEWA), to promote an "open river" – a deep-water shipping channel on the Snake and Columbia Rivers that could compete with rail. The IEWA initially pushed for improvements such as bigger locks at Bonneville Dam in 1938 and the construction of McNary Dam on the Columbia, which would improve navigation to the mouth of the Snake. In 1941 a bill was first introduced in Congress authorizing the Army Corps to develop the lower Snake River. The 1941 bill failed, but after several years of debate, Congress finally authorized the Snake River development in 1945. Early plans included anywhere from six to ten low dams for the lower Snake. Eventually this was reduced to four bigger dams, which would lower costs, but would require what at the time were the tallest navigation locks in the world, at over 100 feet (30 m). Tribes, state wildlife agencies and the fishing industry opposed the dams, arguing that they would kill too many salmon. In 1947, the U.S. Department of the Interior proposed a ten-year moratorium on dam construction while the fishery problem was studied. With the onset of the Cold War, rising electricity demand in the Pacific Northwest – particularly at the nearby Hanford nuclear site – turned the project's focus towards hydropower. By 1948, the Army Corps estimated that over 80 percent of the economic benefits would come from power, and only 15 percent from navigation. Dam opponents countered that if the primary objective was now power, other dam sites existed in the Northwest that would have less impact on fish. These objections proved futile, as the lower Snake River dams were already authorized, and the federal government had little interest in studying alternatives. While opponents continued to stall the project for a few more years, Washington Senator Warren G.

Boise National Forest is a National Forest covering 2,203,703 acres (8,918.07 km2) of the U.S. state of Idaho. Created on July 1, 1908, from part of Sawtooth National Forest, it is managed by the U.S. Forest Service as five units: the Cascade, Emmett, Idaho City, Lowman, and Mountain Home ranger districts. The Idaho Batholith underlies most of Boise National Forest, forming the forest's Boise, Salmon River, and West mountain ranges; the forest reaches a maximum elevation of 9,730 feet (2,970 m) on Steel Mountain. Common land cover includes sagebrush steppe and spruce-fir forests; there are 9,600 miles (15,400 km) of streams and rivers and 15,400 acres (62 km2) of lakes and reservoirs. Boise National Forest contains 75 percent of the known populations of Sacajawea's bitterroot, a flowering plant endemic to Idaho. The Shoshone people occupied the forest before European settlers arrived in the early 19th century. Many of the early settlers were trappers and prospectors before gold was discovered in 1862. After the 1860s Boise Basin gold rush ended, mining of tungsten, silver, antimony, and gold continued in the forest until the mid-twentieth century. Recreation facilities include over 70 campgrounds, whitewater and flatwater boating, cabin rentals, and 1,300 miles (2,100 km) of trails for hiking, biking, horseback riding, and motorized off-road vehicle use.

Archaeological evidence indicates that human habitation in Idaho began towards the end of the last ice age: bone fragments about 10,000 years old have been found in Wilson Butte Cave, an inflationary cave on the Snake River Plain believed to have been occupied by indigenous people until as recently as the 17th century. A change of climate around 7000 years ago dried up much of the Great Basin, forcing the Shoshone people northward into the mountainous areas of central Idaho. Most of what is now Boise National Forest was sparsely inhabited by Native Americans, and several archaeological sites, including campsites, rock shelters, burial grounds, and pictographs have been found along rivers in the area. Trappers and fur traders of European descent first arrived in the area in the early 1800s, starting with John Jacob Astor's Pacific Fur Company in October 1811. Donald Mackenzie and Francois Payette trapped in the area of Boise National Forest in 1819. By 1840, the fur trade was coming to an end, but the westward migration on the Oregon Trail, which passed south of the forest, was beginning. The first settlers moved into the mountains in the 1860s after gold was discovered in Idaho, which forced many of the Shoshone out and led to conflicts throughout the state, including the Bannock War in southern Idaho. Prospectors George Grimes and Moses Splawn were the first to discover gold in the forest at the eponymous Grimes Creek on August 2, 1862. Subsequent gold discoveries at Rocky Bar in 1863 and Atlanta in 1864 increased the rush of people to Idaho, and in 1863 Idaho City, with a population of 6,267, surpassed Portland, Oregon as the largest city in the Pacific Northwest. The Idaho gold rush was largely over by 1870, and the population of the Boise Basin fell from 16,000 to 3,500. In 1898 the forest's first gold dredge was built in Placerville and followed by several others. By 1951, when the last dredges shut down, at least 2.3 million ounces (65.2 million grams) of gold had been produced from the Boise Basin area. Silver was mined along the Crooked River from 1882 until 1921, but a silver mine at Silver Mountain proved unsuccessful. Following a shortage of mercury during World War II, mines in the Stibnite area became the country's largest producer of tungsten and second largest source of mercury. The most important known placer deposit of niobium and tantalum in the United States is located in Bear Valley. From 1953 until 1959, dredges there produced $12.5 million ($138 million today) in niobium, tantalum, and uranium. Other minerals mined in the forest include antimony and molybdenum. U.S. Forest Service Boise National Forest was created on July 1, 1908, from part of Sawtooth National Forest, and originally covered 1,147,360 acres (4,643.2 km2). By the Forest Reserve Act of 1891, the U.S. Congress granted the U.S. President the authority to establish forest reserves out of Public Domain Lands that were subject to disposal (homesteads, sales, etc.) administered by the United States General Land Office, which had been placed under the authority of the U.S. Department of the Interior in 1849. With the passage of the Transfer Act of 1905, forest reserves were transferred to the U.S. Department of Agriculture in the newly created U.S. Forest Service. Present-day Boise National Forest was first protected as part of two forest reserves by proclamations issued by President Theodore Roosevelt: Sawtooth Forest Reserve (created on May 29, 1905, and expanded on November 6, 1906) and Payette Forest Reserve (created on June 3, 1905). After forest reserves were renamed national forests in 1908, Boise National Forest was split from Sawtooth National Forest into an independent national forest. Emile Grandjean was the forest's first supervisor, serving from 1908 to 1922. On April 1, 1944, the entirety of what was then Payette National Forest was transferred to Boise National Forest, and simultaneously Weiser and Idaho national forests were combined to reestablish the present-day Payette National Forest, which is to the north of Boise National Forest. In 1933 the Boise Basin Experimental Forest was created on 8,740 acres (35.4 km2) of the forest near Idaho City to study the management of ponderosa pine. The Lucky Peak Nursery was established in 1959 to produce trees for planting on burned or logged lands on the national forests of the Intermountain region. After the creation of the Civilian Conservation Corps (CCC) in 1933, nine camps and eight subcamps were set up in Boise National Forest, but the number of camps was reduced from 1934 until the program was closed in 1942.

ine Fund, an international non-profit organization founded in 1970 that conserves endangered raptors around the world. Built 42 years ago in 1984, the World Center for Birds of Prey is located on 580 acres (2.3 km2) on a hilltop overlooking Boise, south of the airport and east of Kuna. The campus consists of the business offices of The Peregrine Fund, breeding facilities for endangered raptors, the Velma Morrison Interpretive Center, and the Herrick Collections Building, which houses a large research library and the Archives of Falconry. The Peregrine Fund is known for its worldwide conservation and recovery efforts of rare and endangered raptors. The organization's first recovery effort focused on the peregrine falcon, which was facing extinction due to the widespread use of the chemical DDT. The peregrine falcon was removed from the U.S.

History The Peregrine Fund's original breeding facilities were established at Cornell University in central New York state in 1970 and at a Colorado Division of Wildlife facility in Fort Collins in 1974. They were moved to Boise after the organization established the World Center for Birds of Prey in 1984. Morley Nelson of Boise, a well-known raptor expert and member of The Peregrine Fund board of directors, was instrumental in bringing the organization to his hometown. The first buildings at the new site were an office for The Peregrine Fund administration and barns for the captive breeding program. The organization's first climate-controlled breeding barn (the Gerald D. and Kathryn Swim Herrick Tropical Raptor Building) was constructed in 1986. In 1992, the Velma Morrison Interpretive Center opened to the public with exhibits of rare and endangered raptors, interactive displays, and outreach programs for schools and other groups. In 1993, the first of three California condor breeding barns was constructed. The Gerald D. and Kathryn S. Herrick Collections Building opened in 2002 with space for The Peregrine Fund's research library, scientific specimen collections, and the Archives of Falconry. Research and captive breeding The center's research facilities are designed to enhance the health, reproduction, and reintroduction efforts of endangered species and to collect information about the general biology of raptors. The science is focused on understanding how diet, aging and environment affect the health, growth, reproduction and lifespan of the birds. The propagation program played a critical role in the successful recovery of the peregrine falcon. The organization currently breeds the endangered California condor and aplomado falcon at the World Center for Birds of Prey. The condors are released to the wild in northern Arizona and southern Utah; aplomado falcon chicks are released to the wild in Texas and New Mexico. Captive birds in the breeding facility are monitored by video, which allows the collection of detailed behavioral information.

ise, as well as part of the western Snake River Plain. The watershed encompasses approximately 4,100 square miles (11,000 km2) of highly diverse habitats, including alpine canyons, forest, rangeland, agricultural lands, and urban areas. Description The Boise River rises in three separate forks in the Sawtooth Range at elevations exceeding 10,000 feet (3,050 m), and is formed by the confluence of its North and Middle forks. The North Fork, 50 miles (80 km) long, rises in the Sawtooth Wilderness Area, along the Boise–Elmore county line, 60 miles (100 km) northeast of Boise. It flows generally southwest through the remote mountains in the Boise National Forest. The Middle Fork, approximately 52 miles (84 km) in length, rises within 12 miles (19 km) of the North Fork in the southern Sawtooth Wilderness Area in northeastern Elmore County. It flows west-southwest near the town of Atlanta, joining the North Fork to form the Boise River, approximately 15 miles (24 km) southeast of Idaho City.

History The river was called "Reed's River" in the early 19th century, named after Pacific Fur Company employee John Reed, who explored parts of the river throughout 1813 and 1814. The river is diverted to canals for irrigation on the plain west of what is now Boise. The dams that form the mountain reservoirs were constructed as part of the Bureau of Reclamation's "Boise Project" to provide agricultural irrigation, hydroelectricity, drinking water, and flood control to Boise and the Treasure Valley. The major projects' initial completion dates were: 1909 – Boise River Diversion Dam & New York Canal 1915 – Arrowrock Dam 1950 – Anderson Ranch Dam - (S. Fork) 1955 – Lucky Peak Dam - (U.S. Army Corps of Engineers) The Boise River was proposed for 50 years for a dam at Twin Springs, culminating in a 1966 Project Travois proposal, which would have used nuclear explosives to either create large amounts of rockfill aggregate for dam construction, or to induce a landslide that would have much the same effect. Project Travois was a component of Project Plowshare.

Recreation The river is a popular destination for floating, specifically on the Boise greenbelt. Tubers and floaters launch at Barber Park and land at Ann Morrison Park, between major irrigation diversion dams. Several minor diversion weirs are passed as well as several bridges on the 6-mile (10 km) trip. Water skiing is popular above the dam at the Lucky Peak Reservoir. On the lower (warmwater) course of the river, low summer flows and poorer water quality from agricultural runoff limit fishery production. This section of river supports a fair fishery for largemouth bass, smallmouth bass, and channel catfish. Upstream from Star, the river is a coldwater stream and supports a greater variety of fish. The most prevalent species on this section is mountain whitefish, as well as hatchery-reared rainbow trout, wild rainbow trout, and brown trout. Upstream from Lucky Peak and Arrowrock reservoirs, the river and its tributaries contain excellent populations of wild rainbow trout, mountain whitefish, and bull trout.

rs about a quarter of Idaho. Three major volcanic buttes dot the plain east of Arco, the largest being Big Southern Butte. Most of Idaho's major cities are in the Snake River Plain, as is much of its agricultural land. Geology The Snake River Plain can be divided into three sections: western, central, and eastern. The western Snake River Plain is a large tectonic graben or rift valley filled with several kilometers of Lake Idaho sediments; the sediments are underlain by rhyolite and basalt, and overlain by basalt. The western plain began to form around 11–12 Ma (million years ago) with the eruption of rhyolite lavas and ignimbrites. The western plain is not parallel to North American Plate motion and lies at a high angle to the central and eastern Snake River Plain.

The National Wildlife Refuge System is a system of protected areas of the United States managed by the United States Fish and Wildlife Service, an agency within the Department of the Interior. The National Wildlife Refuge System is the system of public lands and waters set aside to conserve America's fish, wildlife, and plants. Background The mission of the refuge system is: "To administer a national network of lands and waters for the conservation, management, and where appropriate, restoration of fish, wildlife, and plant resources and their habitats within the United States for the benefit of the present and future generations of Americans". The system maintains the biological integrity, diversity, and environmental health of these natural resources and enables for associated public enjoyment of these areas where compatible with conservation efforts. National Wildlife Refuges manage a range of habitat types, including wetlands, prairies, coastal and marine areas, and temperate, tundra, and boreal forests. The management of each habitat is a complex process of controlling or eradicating invasive species, using fire in a prescribed manner, assuring adequate water resources, and assessing external threats such as development or contamination. Hundreds of national refuges are home to some 700 species of birds, 220 species of mammals, 250 reptile and amphibian species, and more than 1000 species of fish. Endangered species are a priority of National Wildlife Refuges, with nearly 60 refuges having the primary purpose of conserving in aggregate 280 threatened or endangered species. The National Wildlife Refuge System welcomes about 65 million visitors each year to participate in outdoor recreational activities. The system manages six wildlife-dependent recreational uses, including hunting, fishing, birding, photography, environmental education, and environmental interpretation. Hunters visit more than 350 hunting programs on refuges and on about 36,000 waterfowl production areas. Opportunities for fresh or saltwater fishing are available at more than 340 refuges. Each state contains at least one refuge. National Wildlife Refuge System employees are responsible for planning, biological monitoring and habitat conservation, contaminants management, visitor services, outreach and environmental education, heavy equipment operation, law enforcement, and fire management. The National Wildlife Refuge System deals with urban intrusion/development, habitat fragmentation, degradation of water quantity and quality, climate change, invasive species, increasing demands for recreation, and increasing demands for energy development. The system has provided a habitat for endangered species, migratory birds, plants, and numerous other valuable animals, implemented the NWRS Improvement Act, acquired and protected key critical inholdings, and established leadership in habitat restoration and management. Under the act, the NWRS has created Comprehensive Conservation Plans (CCPs) for each refuge, developed through consultation with private and public stakeholders. These began a review process by stakeholders beginning in 2013. The CCPs must be consistent with the FWS goals for conservation and wildlife management. The CCPs outline conservation goals for each refuge for 15 years into the future, with the intent that they will be revised every 15 years thereafter. The comprehensive conservation planning process requires a scoping phase, in which each refuge holds public meetings to identify the public's main concerns; plan formulation, when refuge staff and FWS planners identify the key issues and refuge goals; writing the draft plan, in which wildlife and habitat alternatives are developed, and the plan is submitted for public review; revision of the draft plan, which takes into consideration the public's input; and plan implementation. Each CCP is required to comply with the National Environmental Policy Act (NEPA) and must consider potential alternatives for habitat and wildlife management on the refuge, and identify their possible effects on the refuge.

Management activities Comprehensive wildlife and habitat management demands the integration of scientific information from several disciplines, including understanding ecological processes and monitoring status of fish, wildlife and plants. Equally important is an intimate understanding of the social and economic drivers that impact and are affected by management decisions and can facilitate or impede implementation success. Service strategic habitat conservation planning, design, and delivery efforts are affected by the demographic, societal, and cultural changes of population growth and urbanization, as well as people's attitudes and values toward wildlife. Consideration of these factors contributes to the success of the service's mission to protect wildlife and their habitats. The refuge system works collaboratively internally and externally to leverage resources and achieve effective conservation. It works with other federal agencies, state fish and wildlife agencies, tribes, nongovernmental organizations, local landowners, community volunteers, and other partners.

Its surface elevation is approximately 2,520 feet (770 m) above sea level. The Boise Project was among the first undertaken by the Reclamation Service after its formation in 1902. Shortly before leaving office, President Theodore Roosevelt created a national bird refuge at Deer Flat Reservoir, now Lake Lowell, with an executive order on February 25, 1909. The refuge was one of 17 federal reclamation projects referenced in the order, each of which used manmade aquifers to provide safe havens for migratory birds. The effort to include the Canyon County site was spearheaded by James H. Lowell, the president of the local Payette-Boise Water Users Association. The "globally important" Deer Flat National Wildlife Refuge for migratory fowl and other wildlife consists of two sections which contains open water, edge wetlands, grasslands and riparian and forest habitats. The largest portion of the refuge consists of Lake Lowell and its environs.

employers in the technology, manufacturing, and service sectors, including companies such as Micron Technology and Hewlett-Packard. The city is home to the Boise Art Museum, Idaho State Capitol, the annual Treefort Music Fest, and the Basque Block. History Etymology The origin of the name is uncertain. One account credits Capt. B. L. E. Bonneville of the U.S. Army as its source. After trekking for weeks through dry and rough terrain, his exploration party reached an overlook with a view of the Boise River Valley. The place where they stood is called Bonneville Point, located on the Oregon Trail east of the city. According to the story, a French-speaking guide, overwhelmed by the sight of the verdant river, yelled "Les bois! Les bois!" ("The woods! The woods!")—and the name stuck. The name may also derive from earlier mountain men who named the river that flows through the city. In the 1820s, French Canadian fur trappers associated with the British-owned Hudson's Bay Company set trap lines in the vicinity. Set in a high-desert area, the tree-lined valley of the Boise River became a distinct landmark, an oasis dominated by cottonwood trees.

Tribes and First Contact The area of Boise valley was inhabited by Boise Valley Shoshone and Bannock tribes, a part of the "Snake Country". According to the City of Boise's "History of Boise" report, "they gathered annually in the valley to participate in trading rendezvous with other tribes and catch salmon in the Boise River runs to help sustain them year-round. They spent winters in the valley where the climate was milder and visited the hot springs for bathing and healing. Castle Rock, called Eagle Rock by the tribes, was and remains a sacred site." Boise Valley Bannock tribes belonged to the "tuuˀagaidɨkaˀa" (black trout eaters). Boise Valley Shoshone belonged to the "Yahandeka" (groundhog eaters) grouping. They were among the early mounted Shoshone bands. They traveled over a considerable range by the beginning of the nineteenth century, with their main hunting lands along the lower Boise River and Payette River. When Donald MacKenzie developed the Snake country fur trade after 1818, the most prominent of the Boise Shoshone, Peiem (a Shoshoni rendition of "Big Jim", their leader's English name), became the most influential leader of the large composite Shoshoni band that white trappers regularly encountered in the Snake Country. In 1811, Wilson Hunt, employed as an agent in the fur trade under John Jacob Astor, organized and led the greater part of a group of about 60 men on an overland expedition to establish a fur trading outpost at the mouth of the Columbia River. This expedition passed through the Boise valley, and was the first ever time a white American has entered the region. Because of the War of 1812 and the lack of U.S. fur trading posts in the Pacific Northwest, most of the route was not used in the following two decades, and thus Snake Country remained free of settler incursions. After the conclusion of the war of 1812, until the 1840s, Oregon, while officially "jointly administered", was solely dominated by the British Hudson's Bay Company (HBC), which had a land connection to the inland of the Canadian Prairies via York Factory Express. Snake Country, including Boise Valley remained independent and relatively free of settler passage and incursion. There were two main reasons for this. Firstly, the general region east of the Cascades and west of the Rockies was described at the time in the media and literature of the eastern US as the "Great American Desert", an arid unproductive region, unsuitable for habitation. This discouraged settlers from traveling to the region of Boise; however, Oregon Country, on the other side of the Cascades, was a desirable destination for them. Nevertheless, the British had an official policy of discouraging American settlers, and settler incursions into Boise Valley along the Oregon Trail remained low until the early 1840s. The HBC established a fort in the region, the Old Fort Boise, 40 miles (64 km) west, near Parma, down the Boise River near its confluence with the Snake River at the Oregon border.

The North End, generally defined as the part of Boise north of State Street, contains many of the city's older homes. It is known for its tree-lined drives such as Harrison Boulevard, and for its quiet neighborhoods near the downtown area. Downtown Boise is visible from Camel's Back Park. On 13th Street, Hyde Park is home to restaurants and other businesses. The North End also hosts events such as the annual Hyde Park Street Fair. In 2008, the American Planning Association designated Boise's North End one of 10 Great Neighborhoods. Boise Highlands The Boise Highlands is just north of the North End; its location is generally defined as north of Hill Road and east of Bogus Basin Road.

pa ( ) is the most populous city in Canyon County, Idaho, United States. The population was 100,200 at the 2020 census. It is Idaho's third-most populous city. Nampa is about 20 miles (32 km) west of Boise along Interstate 84, and 6 miles (9.7 km) west of Meridian. It is the second principal city of the Boise metropolitan area. The name "Nampa" may have come from a Shoshoni word meaning 'moccasin' or 'footprint'. According to toponymist William O. Bright, the name comes from the Shoshoni word /nampai/, meaning "foot".

History Nampa had its beginnings in the early 1880s when the Oregon Short Line Railroad built a line from Granger, Wyoming, to Huntington, Oregon, that passed through Nampa. In Nampa there is a history museum that marks the railroad's significance. More railroad lines sprang up through Nampa, making it an important railroad town. Alexander and Hannah Duffes established one of the town's first homesteads, eventually forming the Nampa Land and Improvement Company with the help of their friend and co-founder, James McGee. Despite the name, many early settlers called the town "New Jerusalem" because of its citizens' strong religious focus. After only a year the town grew from 15 homes to 50. As amenities were added, Nampa continued to grow, and it was incorporated in 1891. Downtown Nampa's street grid is oriented with the railroad tracks, which run northwest–southeast; this was done intentionally by Alexander Duffes to prevent accidents like one that occurred earlier in a town he had platted near Toronto, where a woman and her two children were killed by a train when their buggy wheel got stuck as they crossed the tracks. As the Oregon Short Line railroad originally bypassed Boise, Nampa has the fanciest of many railroad depots built in the area. Nampa gained attention in 1889 due to a purported archaeological discovery known as the Nampa figurine. George Frederick Wright wrote up details that year for the Boston Society of Natural History. The first elementary school was built in the 1890s. Lakeview School was on a hill on 6th Street and 12th Avenue North, with a view of Lake Ethel. Just after the school's centennial celebration, it was condemned as a school and sold to the First Mennonite Church. In 2008 the building was refurbished, and it is now used by the Idaho Arts Charter School. Lake Ethel, an irrigation reservoir, had long been the site of community picnics, and many citizens fished, swam, boated, and even hunted on it and its surrounding property. But the hunting didn't last long, as O. F. Persons, owner of the adjoining homestead, took offense when local hunters started shooting his pet ducks. The city later auctioned off the lake. E. H. Dewey (a former Nampa mayor) was the only bidder. But occasional flooding led to a series of lawsuits from neighbors. Dewey eventually drained Lake Ethel. Not long after, the city council became interested in buying back the Fritz Miller property as well as the Dewey home. Pressure had been building for more than four years. Nampa citizens wanted another park. On August 7, 1924, the city council passed an ordinance to purchase the Miller property and name it Lakeview Park. A bandstand was completed in 1928, and the municipal swimming pool opened on August 13, 1934. It is Nampa's largest park and many community celebrations are held there. Colonel William H. Dewey, a man who made a fortune mining in Silver City, built the Dewey Palace Hotel in 1902 for $250,000. He died in his hotel in 1903, leaving his son $1 million. The hotel survived the great fire of 1909, which burned several blocks of downtown Nampa, but was razed in 1963 after redevelopment plans failed. Relics from the hotel such as the chandelier and the hotel safe can be found at the Canyon County Historical Museum, which is in the old train depot on Front Street and Nampa City Hall. After demolition the location on First Street between 11th and 12th Ave. South was sold to private enterprise, including a bank and tire store, replacing this building with modern structures. A public-use postage stamp sized park was later placed across the street from the old palace property as a collaboration between the Downtown Alliance of Nampa (the local business council) and an Eagle Scout Project for the Boy Scouts of America. The park includes a large mural/wall sculpture of running horses commissioned for the project. A Carnegie library was built downtown in 1908; it burned down after the library moved in 1966. Nampa Public Library was then on the corner of 1st Street and 11th Avenue South in the old bank building. A new library, on 12th Avenue South, opened in 2015. Deer Flat Reservoir, an offstream irrigation storage reservoir, was constructed by the United States Bureau of Reclamation between 1906 and 1911. Known locally as Lake Lowell, it is surrounded by the Deer Flat National Wildlife Refuge, established in 1909 by President Theodore Roosevelt. The refuge is administered by the U.S. Fish and Wildlife Service. Lake Lowell is filled by the concrete New York Canal; the water is diverted from the Boise River a few miles below Lucky Peak Dam. In 1910, the Idaho State School and Hospital was built northwest of Nampa for the state's developmentally challenged population. It opened in 1918. The institution was largely self-sufficient, with a large farm staffed by the residents. The higher-functioning residents also cared for residents who could not care for themselves. The land for the farm was sold and is now golf courses (Centennial and Ridgecrest), and the residents no longer give primary care to other residents. The institution is modernized and remains in operation, though a few of the oldest buildings now house juvenile offenders. Nampa held an annual harvest festival and farmers' market from about 1908, a time of celebration and community fun. From this festival emerged the Snake River Stampede Rodeo in 1937, which continues to this day. It is one of the top 12 rodeos in the pro rodeo circuits. In 1913, a local congregation of the Church of the Nazarene built a small elementary school, which became to Northwest Nazarene College in 1915 and finally Northwest Nazarene University. As of 2025, the university has approximately 1,800 undergraduate and graduate students. Karcher Mall opened in 1965, the first enclosed shopping mall in the Treasure Valley. It was "the place to gather" for several decades until the Boise Towne Square mall was built in Boise in 1988, drawing business away. Karcher Mall was renamed District 208 in 2022. The Idaho Press-Tribune is the local newspaper for the Canyon County area.

Idaho Hispanic Community Center (IH2C) In 2003, the Hispanic Cultural Center of Idaho (HCCI) opened thanks to community support. It has recently transitioned back to the City of Nampa and was renamed the Idaho Hispanic Community Center (IH2C) and is home to the Idaho Hispanic Foundation. It hosts events, classes, and festivals, including Día de los Muertos, Hispanic Heritage Month, and Día Internacional de la Mujer. It serves as a meeting place for associations and groups. Displays of cultural history are available to the public. Nampa Train Depot Museum The Nampa Train Depot Museum is a historical depot with displays and archives of the area's railroad and cultural history. The Canyon County Historical Society saved the depot from demolition in 1972. Annual Festival of the Arts Nampa's Festival of the Arts, which began in 1987, is held in Lakeview Park every year and includes local art, music, dance, and food.

natural habitats in the United States. The mission of the agency is: "working with others to conserve, protect, and enhance fish, wildlife, plants and their habitats for the continuing benefit of the American people". History Fish Commission and Bureau of Fisheries The original ancestor of the agency was the United States Commission on Fish and Fisheries, more commonly referred to as the United States Fish Commission, created in 1871 by the United States Congress with the purpose of studying and recommending solutions to a noted decline in the stocks of food fish. Spencer Fullerton Baird was appointed to lead it as the first United States Commissioner of Fisheries. In 1903, the Fish Commission was reorganized as the United States Bureau of Fisheries and made part of the United States Department of Commerce and Labor. When the Department of Commerce and Labor was split into the United States Department of Commerce and the United States Department of Labor in 1913, the Bureau of Fisheries was made part of the Department of Commerce. Originally focused on fisheries science and fish culture, the Bureau of Fisheries also assumed other duties; in 1906, the U.S. Congress assigned it the responsibility for the enforcement of fishery and fur seal-hunting regulations in the District of Alaska, and in 1910 for the management and harvest of northern fur seals, foxes, and other fur-bearing animals in the Pribilof Islands, as well as for the care, education, and welfare of the Aleut communities in the islands.

Bureau of Biological Survey The other ancestor of the agency began as the Section of Economic Ornithology, which was established within the United States Department of Agriculture in 1885 and became the Division of Economic Ornithology and Mammalogy in 1886. In 1896 it became the Division of Biological Survey. Clinton Hart Merriam headed the Division for 25 years and became a national figure for improving the scientific understanding of birds and mammals in the United States. By 1905 with funding scarce, the Survey included in its mission the eradication of wolves, coyotes and other large predators. This garnered them the support of ranchers and western legislators resulting, by 1914, in a $125,000 congressionally approved budget for destroying wolves, coyotes and other animals injurious to agriculture and animal husbandry. Meanwhile, scientists like Joseph Grinnell and Charles C. Adams, a founder of the Ecological Society of America, were promoting a balance of nature. In 1924, at a conference organized by the American Society of Mammalogists, the debate generated a public split between those in the Survey, promoting eradication, and the mammalogists who promoted some sort of accommodation. The Survey subsequently placed over 2 million poisoned bait stations across the west. The Survey then turned to the eradication of coyote, coordinated through the 1931 Animal Damage Control Act. In 1934, the Division of Biological Survey was reorganized as the Bureau of Biological Survey and Jay Norwood Darling was appointed its chief;. The same year, Congress passed the Fish and Wildlife Coordination Act, one of the oldest federal environmental review statutes. Under Darling's guidance, the Bureau began an ongoing legacy of protecting vital natural habitat throughout the United States.

The Hanford Reach National Monument in Washington state; The Papahānaumokuākea Marine National Monument, a huge maritime area in the Northwestern Hawaiian Islands; The Aleutian Islands World War II National Monument in the Aleutian Islands in Alaska; The Pacific Islands Heritage Marine National Monument, the largest marine protected area in the world; The Rose Atoll Marine National Monument in American Samoa; The Marianas Trench Marine National Monument, which includes undersea mud volcanoes, vents, chemosynthetic organisms, and many of the deepest points on Earth. Endangered species The agency shares responsibility for administering the Endangered Species Act of 1973 with the National Marine Fisheries Service. The latter is responsible for marine species, while the agency oversees freshwater fish and all other species. The two organizations jointly manage species that inhabit both marine and non-marine environments. To manage the listing process, a listing priority number is assigned to candidate species to reflect the relative urgency of listing them as threatened or endangered when an immediate listing is not feasible.

city in Idaho. As of the 2020 census, Caldwell had a population of 59,996. Caldwell is considered part of the Boise metropolitan area, and is the location of the College of Idaho. The city is located approximately 24 miles (39 km) west of Boise, and approximately 17 miles (27 km) east of the Oregon border. History The present-day location of Caldwell is along a natural passageway to the Inland and Pacific Northwest. Native American tribes from the west coast, north Idaho and as far away as Colorado came to the banks of the Boise River for annual trading fairs, or rendezvous. European and some Hawaiian explorers and traders soon followed the paths left by Native Americans and hopeful emigrants later forged the Oregon Trail and followed those paths to seek a better life in the Oregon Territory. Pioneers of the Trail traveled along the Boise River to Canyon Hill and forded the river close to the Silver Bridge on Plymouth Street. During the Civil War, the discovery of gold in Idaho's mountains brought a variety of new settlers into the area. Many never made it to the mines but settled along the Boise River and run ferries, stage stations, and freighting businesses. These early entrepreneurs created small ranches and farms in the river valleys. Caldwell's inception occurred largely as a result of the construction of the Oregon Short Line Railroad, which connected Wyoming to Oregon through Idaho. Robert E. Strahorn came to the Boise River Valley in 1883 to select a route for the railroad. He rejected the grade into Boise City as too steep and chose a site 30 miles to the west. He drove a stake into an alkali flat of sagebrush and greasewood and the City of Caldwell was platted. Caldwell was named after one of Strahorn's business partners, Alexander Caldwell, a former senator from Kansas. When Caldwell was platted in August 1883, its founder, the Idaho and Oregon Land Improvement Company, started persuading settlers and businessmen to move to the area. Within four months, Caldwell had 600 residents living in 150 dwellings, 40 businesses, a school, a telephone exchange, and two newspapers. On January 15, 1890, the Board of Commissioners of Ada County issued a handwritten order incorporating the City of Caldwell. The College of Idaho was founded in Caldwell in 1891. In 1892, Canyon County was established from a portion of Ada County, and Caldwell was named the county seat. Irrigation canals and waterways were constructed throughout Canyon County, providing the foundation for an agricultural economy. The Oregon Short Line Railroad became part of the larger Union Pacific Railroad network and in 1906 the Caldwell freight and passenger depot was constructed. Caldwell experienced moderate growth as an agricultural processing, commercial retail and educational center during the 20th century. In 2009, the City of Caldwell completed a revitalization project to restore Indian Creek, which runs through downtown Caldwell, but had been used for sewage disposal by local industries and been covered over.

Canyon County, which originally included Payette County and most of Gem County, was partitioned from western Ada County in 1891. Geography According to the United States Census Bureau, the county has a total area of 1,060 square miles (2,700 km2), of which 1,053 square miles (2,730 km2) is land and 7.9 square miles (20 km2) (0.7%) is water. The Boise River flows through the northern portion of the county, and the northwest border is bounded by the foothills of the Boise Range mountains; the summits are in adjacent Boise County.

105, which by 2025 was estimated to have risen to 275,123, making it the second-most populous county in Idaho. The county seat is Caldwell, and its largest city is Nampa. Canyon County is part of the Boise metropolitan area. History Hudson's Bay Company established Fort Boise in 1834 near what is now Parma, but abandoned it in 1855. Emigrants traveled through Canyon County on the Oregon Trail. Discovery of gold in the Boise Basin in 1862 brought settlement to the region again. The lower Boise River was fully contained within Boise County from 1863 until the formation of Ada County in 1864. Settlement of the lower Boise River west of Boise City was limited prior to the completion of the Oregon Short Line Railroad. Middleton was the first European settlement of Canyon County, starting in 1863. The 1870 Census for Ada County listed 76 residents of the Boise Valley, excluding Boise City and the 1880 Census listed 44 residents at Middleton. The arrival of the railroad at Caldwell led to the establishment of a town there as of August 1883. Businessmen James A. McGee and Alexander Duffes filed the plat for nearby Nampa in 1886. Parma was settled around the same time, with the Old Fort Boise post office being moved to the town's location; it was incorporated in 1904. Ada County established precincts for each of the settlements with a combined 1890 Census population of 2,311. Significant settlement of Greenleaf and Notus started around 1904 with the two settlements listed as precincts at the 1910 census. Notus was incorporated in 1921 while Greenleaf was incorporated prior to 1980. Melba was incorporated in 1912 while Wilder was incorporated in 1919. The City of Star annexed a portion of territory in northeast Canyon County prior to 2007, becoming the county's ninth incorporated city. The majority of Star is located within Ada County. The Idaho Legislature created Canyon County from Ada County in an act approved March 7, 1891, effective at the November 26, 1892, election. Caldwell was established as the county seat. The county originally contained all of Canyon and Payette counties and part of Gem; Gem County formed in 1915 and Payette County in 1917.

population was 117,635 at the 2020 census, making it the second most populous city in the county and Idaho, after Boise, the state capital.

Irrigation (1890– ) Early settlers arriving in the area came with no knowledge of gravity flow irrigation. Their previous homes were in areas where rain provided the needed moisture to raise crops. Irrigation soon became a necessity, since having a water source was a requirement for receiving the patent for the land from the U.S. Land Office. Irrigation districts, such as the Nampa-Meridian and Settlers irrigation districts, continue to serve the immediate Meridian area. The town was established in 1891 on the Onweiler farm north of the present site and was called Hunter. Two years later an I.O.O.F. lodge was organized and called itself Meridian because it was located on the Boise Meridian, and the town was renamed. The Settlers' Irrigation Ditch, 1892, changed the arid region into a productive farming community which was incorporated in 1902. Village (1903–41) The original Meridian town site was filed in 1893 on homestead grant land belonging to Eliza Ann Zenger. Her husband, Christian, filed the plat with county officials and called it Meridian. The early settlers, many of whom were relatives, left their homes in Missouri to go west, either by wagon, train, or immigrant railroad car, bringing their lodge and church preferences with them. They established local institutions soon after arriving and filed for homestead lands. Meridian was incorporated in 1903. Around the start of the 20th century, settlers established fruit orchards and built fruit packing businesses and prune dryers along the railroad tracks. Local orchards produced many varieties of apples and Italian prunes. Production continued through the mid-1940s when it was no longer profitable and the businesses closed.

Rail transportation (1908–28) Following the raising of $4,000 to lay the Interurban rail line from Onweiler (Meridian and Ustick Roads), the tracks were completed into the village center. Turning east on Broadway and ending at East Second, the last car would spend the night in Meridian before returning to Boise early the next morning with passengers and freight. The interurban Station and Generator building (west one-third of the old library at Meridian and Idaho Streets) was built in 1912, and the line continued on to Nampa via Meridian. The tracks down Broadway were not used after 1912. The Interurban Company entered into receivership and closed in 1928 after 20 years of providing continuous transportation to neighboring towns. It was Meridian's main connection to the area outside the local community. The Union Pacific Railroad spur opened in 1900 and is currently operated by the Boise Valley Railroad.
