full_context: Document 1: Shadow Mountain Dam: Shadow Mountain Dam is a zoned earth-fill dam on the Colorado River in Grand County, Colorado. Constructed between 1944 and 1946, the Shadow Mountain Dam creates the Shadow Mountain Lake, with a structural height of and a drainage area of . Shadow Mountain Lake is a holding reservoir for water pumped up from Lake Granby just to the south through the Granby Pumping Plant and Canal. Shadow Mountain Lake is connected by a short channel to the natural Grand Lake. The west portal of the Alva B. Adams Tunnel is located on Grand Lake. The Adams Tunnel diverts west slope water to the east slope of the Rocky Mountains for use in agriculture and to serve the populated areas of Colorado, including Denver.
Document 2: Montana: Approximately 66,000 people of Native American heritage live in Montana. Stemming from multiple treaties and federal legislation, including the Indian Appropriations Act (1851), the Dawes Act (1887), and the Indian Reorganization Act (1934), seven Indian reservations, encompassing eleven tribal nations, were created in Montana. A twelfth nation, the Little Shell Chippewa is a "landless" people headquartered in Great Falls, recognized by the state of Montana but not by the U.S. Government. The Blackfeet nation is headquartered on the Blackfeet Indian Reservation (1851) in Browning, Crow on the Crow Indian Reservation (1851) in Crow Agency, Confederated Salish and Kootenai and Pend d'Oreille on the Flathead Indian Reservation (1855) in Pablo, Northern Cheyenne on the Northern Cheyenne Indian Reservation (1884) at Lame Deer, Assiniboine and Gros Ventre on the Fort Belknap Indian Reservation (1888) in Fort Belknap Agency, Assiniboine and Sioux on the Fort Peck Indian Reservation (1888) at Poplar, and Chippewa-Cree on the Rocky Boy's Indian Reservation (1916) near Box Elder. Approximately 63% of all Native people live off the reservations, concentrated in the larger Montana cities with the largest concentration of urban Indians in Great Falls. The state also has a small Métis population, and 1990 census data indicated that people from as many as 275 different tribes lived in Montana.
Document 3: Montana: Montana has 56 counties with the United States Census Bureau stating Montana's contains 364 "places", broken down into 129 incorporated places and 235 census-designated places. Incorporated places consist of 52 cities, 75 towns, and two consolidated city-counties. Montana has one city, Billings, with a population over 100,000; and two cities with populations over 50,000, Missoula and Great Falls. These three communities are considered the centers of Montana's three Metropolitan Statistical Areas.
Document 4: Hoover Dam: Hoover Dam is a concrete arch - gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives. Originally known as Boulder Dam from 1933, it was officially renamed Hoover Dam, for President Herbert Hoover, by a joint resolution of Congress in 1947.
Document 5: Montana: The United States Census Bureau estimates that the population of Montana was 1,032,949 on July 1, 2015, a 4.40% increase since the 2010 United States Census. The 2010 census put Montana's population at 989,415 which is an increase of 43,534 people, or 4.40 percent, since 2010. During the first decade of the new century, growth was mainly concentrated in Montana's seven largest counties, with the highest percentage growth in Gallatin County, which saw a 32 percent increase in its population from 2000-2010. The city seeing the largest percentage growth was Kalispell with 40.1 percent, and the city with the largest increase in actual residents was Billings with an increase in population of 14,323 from 2000-2010.
Document 6: Gibson Dam: Gibson Dam is a concrete arch dam on the Sun River, a tributary of the Missouri River, about west of Great Falls, Montana in the United States. Located on the eastern edge of the Rocky Mountains, the dam was built by the U.S. Bureau of Reclamation (USBR) between 1926 and 1929 as part of the Sun River Project to develop about of irrigated land in the Sun River Valley.
Document 7: Glacier View Dam: Glacier View Dam was proposed in 1943 on the North Fork of the Flathead River, on the western border of Glacier National Park in Montana. The tall dam, to be designed and constructed by the U.S. Army Corps of Engineers in the canyon between Huckleberry Mountain and Glacier View Mountain, would have flooded in excess of of the park. In the face of determined opposition from the National Park Service and conservation groups, the dam was never built.
Document 8: Montana: East of the divide the Missouri River, which is formed by the confluence of the Jefferson, Madison and Gallatin rivers near Three Forks, flows due north through the west-central part of the state to Great Falls. From this point, it then flows generally east through fairly flat agricultural land and the Missouri Breaks to Fort Peck reservoir. The stretch of river between Fort Benton and the Fred Robinson Bridge at the western boundary of Fort Peck Reservoir was designated a National Wild and Scenic River in 1976. The Missouri enters North Dakota near Fort Union, having drained more than half the land area of Montana (82,000 square miles (210,000 km2)). Nearly one-third of the Missouri River in Montana lies behind 10 dams: Toston, Canyon Ferry, Hauser, Holter, Black Eagle, Rainbow, Cochrane, Ryan, Morony, and Fort Peck.
Document 9: Montana: Montana has a larger Native American population numerically and percentage-wise than most U.S. states. Although the state ranked 45th in population (according to the 2010 U.S. Census), it ranked 19th in total native people population. Native people constituted 6.5 percent of the state's total population, the sixth highest percentage of all 50 states. Montana has three counties in which Native Americans are a majority: Big Horn, Glacier, and Roosevelt. Other counties with large Native American populations include Blaine, Cascade, Hill, Missoula, and Yellowstone counties. The state's Native American population grew by 27.9 percent between 1980 and 1990 (at a time when Montana's entire population rose just 1.6 percent), and by 18.5 percent between 2000 and 2010. As of 2009, almost two-thirds of Native Americans in the state live in urban areas. Of Montana's 20 largest cities, Polson (15.7 percent), Havre (13.0 percent), Great Falls (5.0 percent), Billings (4.4 percent), and Anaconda (3.1 percent) had the greatest percentage of Native American residents in 2010.

These included a Native American language (64 percent), German (4 percent), Spanish (3 percent), Russian (1 percent), and Chinese (less than 0.5 percent).
Document 11: Gibson Reservoir: Gibson Reservoir is located just south of the Bob Marshall Wilderness in Montana. The reservoir is formed by the concrete arch Gibson Dam and backs water up between a hilly pass for about 3 miles. The water in the dam is initially provided by spring snow runoff and carried there via the North Fork Sun River and the South Fork Sun River right after the two join. The reservoir is mainly used for irrigation control.

Additionally, there are over 10,000 invertebrate species, including 180 mollusks and 30 crustaceans. Montana has the largest grizzly bear population in the lower 48 states. Montana hosts five federally endangered species–black-footed ferret, whooping crane, least tern, pallid sturgeon and white sturgeon and seven threatened species including the grizzly bear, Canadian lynx and bull trout.

Document 14: Keyhole State Park: The Keyhole Reservoir, an impoundment of the Belle Fourche River, was formed by the Keyhole Dam project of the United States Bureau of Reclamation, completed in 1952. The reservoir has a total capacity of 334,200 acre-feet and water surface of 13,700 acres, which provides storage for irrigation, flood control, fish and wildlife conservation, recreation, sediment control, and municipal and industrial water supply. Although located in Wyoming, the reservoir's waters are allocated by compact to go 90 percent to South Dakota and 10 percent to Wyoming.
Document 15: Ryan Dam: Ryan Dam is a hydroelectric dam on the Missouri River, downstream from the city of Great Falls in the U.S. state of Montana. The dam is long and high; its reservoir is long and has a storage capacity of . It is a run-of-river dam. The dam is built on the largest of the five Great Falls of the Missouri, the "Big Falls", also sometimes called "Great Falls". Since 1915, the six-unit powerhouse on the left side of the dam has occupied a significant portion of the high waterfall.
