Crawford Lake (Wyandot: Kionywarihwaen[3][4]) is a lake near the community of Campbellville, in the town of Milton, Regional Municipality of Halton, Ontario, Canada.[1][5] It is located within Crawford Lake Conservation Area, a Regionally Environmentally Sensitive Area, an Ontario Area of Natural and Scientific Interest, and part of the Niagara Escarpment World Biosphere Reserve.[6]

The primary inflow to the lake is an unnamed creek.

Crawford Lake is meromictic,[6] which means it has sequentially deposited seasonal sediment laminations called varves at the bottom; these allow for accurate dating of sediment cores and make Crawford Lake a prime site for archeological and geochemical studies.
