North Dakota is a state in the western UCAS.
North Dakota's western border has been redrawn, and almost a third of the state's western land has been ceded to the Sioux. The new border runs down the middle of the Missouri river, leaving Bismarck in the control of the UCAS.
In the last century the Missouri river has been dammed (Garrison Dam) to create Lake Sakakawea and Lake Audobon. Straddling much of the lake is the Fort Berthold Native Reservation. The dam was constructed between 1947 and 1954, is two miles in length, and was the fifth largest earthen dam in the world.
The Fort Berthold Indian Reservation was an extensive U.S. Indian reservation in western North Dakota that was home for the federally recognized Mandan , Hidatsa , and Arikara Nation, also known as the Three Affiliated Tribes. The reservation includes lands on both sides of the Missouri River.
Fort Berthold sits smack dab on some of North Dakota's prime oil-country, which sits beneath much of the western third of the state, most of which coincidentally is now part of the Sioux Nation (in the Sixth World).
The construction of the $300 million dam began saw the forced relocation of 1700 Native American residents, who resided in the area that would be flooded by the dam resevoir. Threatened by confiscation under eminent domain, the tribes protested. The final settlement legislation denied tribes' right to use the reservoir shoreline for grazing, hunting, fishing or other purposes, including irrigation development and royalty rights on all subsurface minerals within the reservoir area. The dam would eliminate up to 94% of the tribes' agricultural land, effectively destroying the tribes' traditional way of life.
