The Missouri River is the longest river in the United States. Rising in the Rocky Mountains of the Eastern Centennial Mountains of Southwestern Montana, the Missouri flows east and south for 2,341 miles (3,767 km) before entering the Mississippi River north of St. Louis, Missouri. The river drains a sparsely populated, semi-arid watershed of more than 500,000 square miles (1,300,000 km2), which includes parts of ten U.S. states and two Canadian provinces. Although a tributary of the Mississippi, the Missouri River is much longer and carries a comparable volume of water. When combined with the lower Mississippi River, it forms the world's fourth longest river system.
Fort Yates is a city in Sioux County, North Dakota, United States. It is the tribal headquarters of the Standing Rock Sioux Tribe and county seat of Sioux County.

Garrison Dam is an earth-fill embankment dam on the Missouri River in central North Dakota, U.S. Constructed by the U.S. Army Corps of Engineers from 1947 to 1953, at over 2 miles (3.2 km) in length, the dam is the fifth-largest earthen dam in the world. The reservoir impounded by the dam is Lake Sakakawea, which extends to Williston and the confluence with the Yellowstone River, near the Montana border.
The Grand River is a tributary of the Missouri River in South Dakota in the United States. The length of the combined branch is 110 mi (177 km). With its longest fork, its length is approximately 200 mi (320 km).
The Cheyenne River, also written Chyone, referring to the Cheyenne people who once lived there, is a tributary of the Missouri River in the U.S. states of Wyoming and South Dakota. It is approximately 295 miles (475 km) long and drains an area of 24,240 square miles (62,800 km2). About 60% of the drainage basin is in South Dakota and almost all of the remainder is in Wyoming.
The Pick–Sloan Missouri Basin Program, formerly called the Missouri River Basin Project, was initially authorized by the Flood Control Act of 1944, which approved the plan for the conservation, control, and use of water resources in the Missouri River Basin.
The Fort Peck Dam is the highest of six major dams along the Missouri River, located in northeast Montana in the United States, near Glasgow, and adjacent to the community of Fort Peck. At 21,026 feet (6,409 m) in length and over 250 feet (76 m) in height, it is the largest hydraulically filled dam in the United States, and creates Fort Peck Lake, the fifth largest artificial lake in the U.S., more than 130 miles (210 km) long, 200 feet (61 m) deep, and it has a 1,520-mile (2,450 km) shoreline which is longer than the state of California's coastline. It lies within the Charles M. Russell National Wildlife Refuge. The dam and the 134-mile-long (216 km) lake are owned and operated by the U.S. Army Corps of Engineers and exist for the purposes of hydroelectric power generation, flood control, and water quality management.
The Oahe Dam is a large earthen dam on the Missouri River, just north of Pierre, South Dakota, United States. The dam creates Lake Oahe, the fourth-largest man-made reservoir in the United States. The reservoir stretches 231 miles (372 km) up the course of the Missouri to Bismarck, North Dakota. The dam's power plant provides electricity for much of the north-central United States. It is named for the Oahe Indian Mission established among the Lakota Sioux in 1874.
Lake Oahe is a large reservoir behind Oahe Dam on the Missouri River; it begins in central South Dakota and continues north into North Dakota in the United States. The lake has an area of 370,000 acres (1,500 km2) and a maximum depth of 205 ft (62 m). By volume, it is the fourth-largest reservoir in the US. Lake Oahe has a length of approximately 231 mi (372 km) and has a shoreline of 2,250 mi (3,620 km). 51 recreation areas are located along Lake Oahe, and 1.5 million people visit the reservoir every year. The lake is named for the 1874 Oahe Indian Mission.
Wakpala is an unincorporated community in Corson County, South Dakota, United States, on the west side of the Missouri River, north-northwest of Mobridge. Although not tracked by the Census Bureau, Wakpala has been assigned the ZIP code of 57658.

The Standing Rock Reservation lies across the border between North and South Dakota in the United States, and is inhabited by ethnic "Hunkpapa and Sihasapa bands of Lakota Oyate and the Ihunktuwona and Pabaksa bands of the Dakota Oyate," as well as the Hunkpatina Dakota. The Ihanktonwana Dakota are the Upper Yanktonai, part of the collective of Wiciyena. The sixth-largest Native American reservation in land area in the US, Standing Rock includes all of Sioux County, North Dakota, and all of Corson County, South Dakota, plus slivers of northern Dewey and Ziebach counties in South Dakota, along their northern county lines at Highway 20.
The Great Sioux Reservation initially set aside land west of the Missouri River in South Dakota and Nebraska for the use of the Lakota Sioux, who had dominated this territory. The reservation was established in the Fort Laramie Treaty of 1868. It included all of present-day western South Dakota and modern Boyd County, Nebraska. This area was established by the United States as a reservation for the Teton Sioux, also known as the Lakota: the seven western bands of the "Seven Council Fires".
The Cheyenne River Indian Reservation was created by the United States in 1889 by breaking up the Great Sioux Reservation, following the attrition of the Lakota in a series of wars in the 1870s. The reservation covers almost all of Dewey and Ziebach counties in South Dakota. In addition, many small parcels of off-reservation trust land are located in Stanley, Haakon, and Meade counties.
Post at Grand River Indian Agency was a Federal military post at the Grand River Indian Agency between 1870 and 1875 in the Dakota Territory. It was located at the Missouri and Grand Rivers, near modern Wakpala, Corson County, South Dakota within the Standing Rock Indian Reservation.
The Dakota Access Pipeline Protests, also called by the hashtag #NoDAPL, began in April 2016 as a grassroots opposition to the construction of Energy Transfer Partners' Dakota Access Pipeline in the northern United States and ended on February 23, 2017 when National Guard and law enforcement officers evicted the last remaining protesters. The pipeline runs from the Bakken oil fields in western North Dakota to southern Illinois, crossing beneath the Missouri and Mississippi rivers, as well as under part of Lake Oahe near the Standing Rock Indian Reservation. Many members of the Standing Rock tribe and surrounding communities consider the pipeline to be a serious threat to the region's water. The construction also directly threatens ancient burial grounds and cultural sites of historic importance.

Eagle Woman That All Look At was a Lakota activist, diplomat, trader, and translator, who was known for her efforts mediating the conflicts between white settlers, the United States government, and the Sioux. She is credited with being the only woman recognized as a chief among the Sioux.
The Dakota Access Pipeline (DAPL) or Bakken pipeline is a 1,172-mile-long (1,886 km) underground pipeline in the United States that has the ability to transport up to 750,000 barrels of light sweet crude oil per day. It begins in the shale oil fields of the Bakken Formation in northwest North Dakota and continues through South Dakota and Iowa to an oil terminal near Patoka, Illinois. Together with the Energy Transfer Crude Oil Pipeline from Patoka to Nederland, Texas, it forms the Bakken system. The pipeline transports 40 percent of the oil produced in the Bakken region.
