Lake Gibson is a lake near Thorold in the Regional Municipality of Niagara, Ontario, Canada. The lake is not natural, but rather was created as a reservoir for hydroelectric power generation at the Ontario Power Generation Decew Falls 1 and Decew Falls 2 generating stations.[3] The lake was created by flooding the shallow valley of Beaverdams Creek.[4] Lake Moodie is located to the northwest of Lake Gibson and is a smaller segment of the overall Lake Gibson system.[3] Almost all of the water supply to these lakes comes from Lake Erie via the Welland Canal.[3] The lakes form part of the Twelve Mile Creek watershed.[3]
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.[5] A short distance east of this are the ruins of DeCou House, the destination of Laura Secord's famous journey during the War of 1812.
