, by which it set aside a reservation solely for use of the Flathead, encompassing an area including much of Flathead Lake.
By the late 19th and early 20th century, the federal government had adopted a policy of allotting lands to individual Indian households from their communal holdings, in order to encourage subsistence farming and adoption of European-American ways.

Although the Flathead opposed such European-style allotments and farming, the US Congress passed the 1904 Flathead Allotment Act. Construction of the Flathead Indian Irrigation Project using the Mission Mountains as the water source was also authorized by Congress. Thousands of acres on the reservation were reserved for town sites, schools and the
National Bison Range. The Flathead were given first choice of either of land per household.
According to their treaty, the tribes have the right to off-reservation hunting, but the state believed it could regulate those activities. State game wardens were responsible for a violent confrontation in 1908 with a small Pend d'Oreilles hunting party, which resulted in deaths of four of the Native Americans, in what is known as the
Swan Valley Massacre. A court challenge to their hunting rights reached the US Supreme Court, which upheld tribal treaty rights to hunt off-reservation in their former territory.
After allotments of land to individual households of members on the tribal rolls, the government declared the rest of the communal land to be "surplus" and opened the reservation to

settlement. United States Senator
Joseph M. Dixon of Montana played a key role in getting this legislation passed. Most tribal members chose land close to the mountains where wild game still roamed, so prime farmland in the middle of the valleys was available. When it opened in 1910, 81,363 applications by whites were received for 1,600 parcels of land. Lottery winners took only 600 tracts, leaving 1,000 tracts still open. These were taken in what the tribe considers a subsequent "land grab". The distribution of the lands caused much resentment by the Flathead as homesteaders started fencing the land, claiming water rights from streams and diverting water for irrigation. Congress amended the act to authorize the construction of irrigation systems for homesteaded lands within the reservation. The
United States Reclamation Service began reconnaissance surveys in 1907 and actual work commenced in the summer of 1908. The tribes requested the establishment of the
Pablo National Wildlife Refuge which was established in 1921, subject to reservoir uses for the irrigation project. The Tribes manage the fishery resources in the Pablo Reservoir. Originally a joint project, the
Indian Service gained control of Flathead Irrigation Project in 1924. With the rugged mountains and valleys, numerous waterways diverse in size, and a large amount of natural lakes, the project was not completed until 1963.
Management
A tribal council was formed in response to the 1934
Indian Reorganization Act
The Indian Reorganization Act (IRA) of June 18, 1934, or the Wheeler–Howard Act, was U.S. federal legislation that dealt with the status of American Indians in the United States. It was the centerpiece of what has been often called the "Indian ...
. They were the first tribes to organize a tribal government under the act. Under the
, the tribal council was finally able to begin gradually taking over management of law enforcement, justice, forestry, wildlife, and health and human services programs. The Flathead have worked to regain control of the reservation lands and acquire some of the approximately one-half of the land base appropriated by non-Indians. The allotment of reservation lands remains "a very sensitive issue".
The tribes applied to Congress and began managing the Mission Valley Power Company in 1988, which serves the reservation. Their bid to take over the federal operating license for
Kerr Dam wasn't successful, but the tribes obtained exclusive rights to purchase the facility in 2015, and a larger rent payment.
The Flathead Indian Irrigation Project had been operated by the Bureau of Indian Affairs (BIA) since they assumed management from the Bureau of Reclamation in 1993. It has 17 reservoirs, of canals and more than 10,000 structures. After seven years of technical work on issues that included rights-of-ways, treaty-protected fisheries, biological resources, wildlife habitat and Native American traditional and cultural properties and resources, the Flathead Indian Irrigation Project Cooperative Management Entity was formed in 2010. The cooperative was the result of negotiations between the Flathead Joint Board of Control which represents non-Indian irrigation interests in the Flathead, Mission and Jocko Valley irrigation districts and the tribes. While the federal government would retain ownership, this was the first management partnership where management was taken over from the BIA on an irrigation project. Under the Cooperative, some of the irrigators were concerned that the tribes had equal representation as non-tribal farmers and ranchers, who they claim own 90 percent of the project's irrigable land.
The use of the irrigation project by both Tribal and non-tribal members also complicated the nearly 2-decades-long-statewide effort to negotiate water rights settlements with all of Montana's tribes. The 2013 Montana Legislature failed to pass the Flathead Water Rights Compact after 12 years of negotiations with the tribes by the Montana Reserved Water Rights Compact Commission. In 2014, the BIA resumed management of the irrigation project. In 2015, the tribes acquired the dam, renaming it as the Seli'š Ksanka Qlispe' Dam. They are the first tribe to own a hydroelectric dam. It generates hydroelectric power for the region. The Confederated Salish and Kootenai Tribes – Montana Compact was ratified by the Tribes on December 29, 2020. This water rights compact with the state and federal government, with an effective date of September 17, 2021, established a regulatory body composed of members appointed by both the State of Montana and CSKT as the authority for all water right permitting and changes within the Flathead Indian Reservation in perpetuity. The Montana Water Rights Protection Act, passed by Congress to approve the compact, provided funding to rebuild the Flathead Irrigation Project.

Polson, the county seat of Lake County, is located at the southern end of the lake and within the reservation boundaries. The Flathead River flows south and west from Flathead Lake and exits in the southwestern corner of the reservation. Virtually all streams within the reservation are tributaries of the Flathead River. Mission Valley is centrally located within the reservation and surrounded on the eastern, western, and southern sides by mountain ranges.

Mission Mountains Wilderness. The southern end of the Mission Mountains includes a large grizzly bear protection area which is usually closed to hikers from July thru September. This allows the bears to feed on lady bugs and cut worms, and attempts to keep bear-human contact to a minimum.

s. The
National Bison Range was established on May 23, 1908, out of a portion of the reservation when it was realized that the
Bison were almost extinct.
The initial herd for the range, obtained from local ranchers, were the same animals (or their direct descendants) that had previously flourished on the reservation after being gathered by tribal members. After more than a century of federal management and nearly two decades of negotiations with the
U.S. Fish and Wildlife Service, the site was restored to the tribes in 2022. U.S. Department of the Interior Assistant Secretary Tara Katuk Sweeney stated that "The CSKT have strong and deep historical, geographic and cultural ties to the land and the bison, and their environmental professionals have been leaders in natural resources and wildlife management for many decades."
The tribe is teaching members to raise traditional vegetables with at least eight gardens on the reservation. Some of the vegetables are used in a soup that is delivered to tribal elders.
Economy

The tribes derive income from selling timber and from operating a variety of businesses:

There are 26 places (including

After the allotment and homesteading at the turn of the 20th century, white settlers gained ownership to about one-half of the land on the reservation. Since the late 20th century, the tribe has been steadily buying back the land over many years. The Flathead own about 2/3 of the land on the reservation.
