Water achieves it maximum density at roughly $4^{o} C$ ,i.e. water (including ice) at all other temperatures below or above $4^{o} C$ is less dense. Since matter is ordered from top to bottom by increasing density, any $4^{o} C$ water in a lake will be found at the bottom.

Water achieves it maximum density at roughly 4oC,i.e. water (including ice) at all other temperatures below or above 4oC is less dense. Since matter is ordered from top to bottom by increasing density, any 4oC water in a lake will be found at the bottom.
