Lake Kelso is a man-made reservoir which was created to control the flooding of Sixteen Mile Creek in Milton, Ontario. It is found within Kelso Conservation Area and is maintained by Conservation Halton.

One of the founders of Conservation Halton, Allan Day, recalls that before the reservoir was built, "Milton used to get flooded every spring thaw. Milton's main street would get flooded." It was Day who convinced the previous landowner to sell his property to the Sixteen-Mile Creek Authority in 1961. The authority purchased the land for $40 000 before erecting a $325 000 water control dam a few years later.
