Lillooet, BC, District Municipality, pop 2324 (2006c), 2741 (2001c), inc 1996. Lillooet is located in the southern interior of British Columbia, 325 km northeast of Vancouver. It sits at the eastern edge of the COAST MOUNTAINS above the west bank of the FRASER RIVER. Lillooet is an important location in native history and culture and remains one of the main population centres of the St'at'imc (Lillooet Nation), an INTERIOR SALISH group. Originally known as Cayoosh Flat because the body of a dead cayuse (native pony) was found in the river, the community was renamed, in 1860, after the Lillooet. It first became a municipality in 1946, when it was incorporated as a village.
