Highway 406 crosses over the lake. At the west end of the lake is Morningstar Mill consisting of a working gristmill dating from 1872, plus a reconstructed sawmill. A short distance east of this can be found the ruins of DeCou House, the destination of Laura Secord's famous journey during the War of 1812.
Lake Gibson is part of St. Catharines' drinking water supply. Consequently, no boating is permitted.
