}} known by several terms including leat and mill stream. The channel or stream leading from the mill pond is the mill race, which together with weirs, dams, channels and the terrain establishing the mill pond, delivers water to the mill wheel to convert potential and/or kinetic energy of the water to mechanical energy by rotating the mill wheel. The production of mechanical power is the purpose of this civil engineering hydraulic system.
The term mill pond is often used colloquially and in literature to refer to a very flat body of water.{{cite web|url=http://dictionary.reference.com/browse/Mill%20pond|access-date=7 September 2013
