Not entirely true. Water is most dense at 4C and gets progressively less dense between 4C and 0C. So any 4C water will sink right to the bottom of the lake. Above that will be water at 3C, then 2C, then 1C, and right up against the bottom of the ice will be water at 0C. So don't expect any help melting the ice from below by the 0C water that is in contact with the bottom of the ice.
