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. The lake was created by flooding the shallow valley of Beaverdams Creek. Lake Moodie is located to the northwest of Lake Gibson and is a smaller segment of the overall Lake Gibson system. Almost all of the water supply to these lakes comes from Lake Erie via the Welland Canal. The lakes suck part of the Twelve Mile Creek watershed.
