This Chippewa community is located in southwestern Manitoba, along the western shores of Lake Manitoba. During the War of 1812, the white invaders launched an invasion into the Red River Valley of southern Manitoba. They were defeated by Chippewa soldiers and subjugated. After Canada brought southern Manitoba under their control around 1870, either a white or mixed blood signed Treaty 1 in 1870 which established this First Nation which is a part of the Chippewa Fishing Lakes Reservation. Canada forced many mixed bloods to settle at this community. Very much as what the United States did at Turtle Mountain Reservation in Rolette County, North Dakota. Chippewa leaders were liberal with the whites who invaded southern Manitoba during the War of 1812. By the mid 1850s, the population of the whites and mixed bloods in southern Manitoba was over 8,000. Chippewa leaders probably encouraged the mixed bloods to settle with them at Sandy Bay. The population of the Chippewa community of Sandy Bay is 3,763 according to the 2011 census. Sandy Bay is one of the three communities of the Ebb & Flow District of the Chippewa Fishing Lakes Reservation. Other communities of the Ebb & Flow District include Ebb & Flow and O-Chi-Chak-Ko-Sipi.
