'Kinbasket Lake' was adopted in the 11th Report of the Geographic Board of Canada, 30 June 1912, applied to a small natural lake at 51° 57' - 118° 04' (as shown on 82M/16E). Lake disappeared due to flooding behind Mica Dam. The entire pondage was named 'McNaughton Lake' 15 October 1973 on 82 NW, 83 SW and MCR5 sheet 3, as determined by Cabinet (see Victoria Times, 10 August 1973). Name changed to 'Kinbasket Lake' 7 February 1980 by unanimous approval of Cabinet, as recommended 5 February 1980 by Cabinet Committee on Economic Development, in response to local pressure to reinstate the historic name, Kinbasket.
