Many of the cottages on the north-east side are built on land leased from Wahta Mohawk families, and accessed by privately maintained roads.

On February 7, 2005 Chief Blaine Commandant of the Wahta Mohawks, the Honourable Andy Scott, Minister of Indian Affairs and Northern Development, and the Honourable Michael Bryant, Ontario Minister Responsible for Native Affairs announced the settlement of a land claim dating back to 1918.

The lands to be transferred to the First Nation under the settlement are located adjacent to the existing Wahta Mohawk Territory (the Gibson Reserve).

Gibson Lake contains a small island where a yearly picnic festival and regatta takes place on the first weekend of August.

Prizes and trophies for winners of swimming, canoeing, and tubing competitions are sponsored by the Gibson Lake Cottage Association.
