The Lower Sioux Indian Community, (Dakota: Caŋṡa'yapi; Lakota: Čhaŋšáyapi[1]) also known as the Mdewakanton Tribal Reservation, is an Indian reservation located along the southern bank of the Minnesota River in Paxton and Sherman townships in Redwood County, Minnesota.

[3] The area around the reservation is primarily rural, developed in the 21st century for agricultural commodity crops of corn and soybeans.

The conversion of area creeks to agricultural ditches has also altered habitat and reduced the diversity of the ecology.

On January 26, 1955 Senator Edward Thye introduced a bill (S704) to provide for termination of the tribes.

The Minnesota Governor's Commission on Human Rights also opposed the legislation, indicating that it would "not adequately protect the interests of the Indians...".

[5] In 2021, the Minnesota state legislature and Minnesota Historical Society returned half of the lands to the Lower Sioux Community that were located in the former Lower Sioux Agency and were taken by the federal government as punishment after the Dakota War of 1862.

[8] The Mdewakanton tribe operates Jackpot Junction Casino Hotel, which began in 1984 as a bingo facility.

In addition to the gaming areas, Jackpot Junction features three bars, three restaurants, an amphitheater for live performances, and two grand ballrooms.
