Columbia River Treaty The Columbia River Treaty is a 1964 agreement between Canada and the United States on the development and operation of dams in the upper Columbia River basin for power and flood control benefits in both countries. Four dams were constructed under this treaty: three in British Columbia, Canada (Duncan Dam, Mica Dam, Keenleyside Dam) and one in Montana in the United States (Libby Dam). The treaty provided for the sharing with Canada of one-half of the downstream U.S. power and flood benefits, and allows the operation of Treaty storage for other benefits. The long-term impacts of the treaty have been mixed: while the dams have provided enormous economic benefits to British Columbia and the U.S. Pacific Northwest through hydroelectric generation and flood control, there are longstanding concerns regarding social and economic impacts to the local communities, and the environmental effects associated with the construction and operation of large dams.

Nisga'a Final Agreement The Nisga'a Final Agreement, also known as the Nisga'a Treaty, is a treaty settled between the Nisg̱a'a, the government of British Columbia, and the Government of Canada. As part of the settlement in the Nass River valley nearly 2,000 square kilometres of land was officially recognized as Nisg̱a'a, and a 300,000 cubic decameter water reservation was also created. Bear Glacier Provincial Park was also created as a result of this agreement. Thirty-one Nisga'a placenames in the territory became official names. The land-claim settlement was the first formal treaty signed by a First Nation in British Columbia since the Douglas Treaties in 1854 (pertaining to areas on Vancouver Island) and Treaty 8 in 1899 (pertaining to northeastern British Columbia). The agreement gives the Nisga'a control over their land, including the forestry and fishing resources contained in it.

Missouri National Recreational River The Missouri National Recreational River is located on the border between Nebraska and South Dakota. The designation was first applied in 1978 to a 59-mile section of the Missouri River between Gavins Point Dam and Ponca State Park. In 1991, an additional 39-mile section between Fort Randall Dam and Niobrara, Nebraska, was added to the designation. These two stretches of the Missouri River are the only parts of the river between Montana and the mouth of the Missouri that remain undammed or unchannelized. The last 20 miles of the Niobrara River and 6 miles of Verdigre Creek were also added in 1991.

Black Eagle Dam Black Eagle Dam is a hydroelectric gravity weir dam located on the Missouri River in the city of Great Falls, Montana. The first dam on the site, built and opened in 1890, was a timber-and-rock crib dam. This structure was the first hydroelectric dam built in Montana and the first built on the Missouri River. The dam helped give the city of Great Falls the nickname "The Electric City." A second dam, built of concrete in 1926 and opened in 1927, replaced the first dam, which was not removed and lies submerged in the reservoir. Almost unchanged since 1926, the dam is 782 ft long and 34.5 ft high, and its powerhouse contains three turbines capable of generating seven megawatts (MW) of power each. The maximum power output of the dam is 18 MW. Montana Power Company built the second dam, PPL Corporation purchased it in 1997 and sold it to NorthWestern Corporation in 2014. The reservoir behind the dam has no official name, but was called the Long Pool for many years. The reservoir is about 2 mi long, and has a storage capacity of 1,710 acre.ft to 1,820 acre.ft of water.

Great Falls (Missouri River waterfall) Great Falls (also called Grand Falls or Big Falls) is a major waterfall located on the Missouri River in western Montana in the United States. It is the lowermost and largest of the eponymous Great Falls of the Missouri, at 87 ft high and up to 900 ft wide at peak flow. Although the falls used to flow powerfully year-round, most of the water is now diverted to the 60 megawatt hydroelectric plant of upstream Ryan Dam, reducing it to a trickle in the summer months. Grand Falls was named by William Clark of the Lewis and Clark Expedition in 1805.

Seton Dam Seton Dam is a dam on the Seton River, 350m below the outlet of Seton Lake 5 km west of the town of Lillooet, British Columbia, Canada, and with the related Seton Canal is part of the lowest and last stage of the Bridge River Power Project. The 18 meter high concrete dam, completed in 1956, raised the height of Seton Lake only 10 feet in order to maximize the elevation differential between that lake and the Fraser River in order to extract the maximal potential output of power generation at the Seton Powerhouse, which is located on the Fraser just south of the confluence of the Seton River proper.

Deschutes River (Oregon) The Deschutes River in central Oregon is a major tributary of the Columbia River. The river provides much of the drainage on the eastern side of the Cascade Range in Oregon, gathering many of the tributaries that descend from the drier, eastern flank of the mountains. The Deschutes provided an important route to and from the Columbia for Native Americans for thousands of years, and then in the 19th century for pioneers on the Oregon Trail. The river flows mostly through rugged and arid country, and its valley provides a cultural heart for central Oregon. Today the river supplies water for irrigation and is popular in the summer for whitewater rafting and fishing.

Fur trade in Montana The fur trade in Montana was a major period in the area's economic history from about 1800 to the 1850s. It also represents the initial meeting of cultures between indigenous peoples and those of European ancestry. British and Canadian traders approached the area from the north and northeast focusing on trading with the indigenous people, who often did the trapping of beavers and other animals themselves. American traders moved gradually up the Missouri River seeking to beat British and Canadian traders to the profitable Upper Missouri River region.
