<onlyinclude>The '''tail race''', containing '''tail water''', is a channel that carries [[water]] away from a [[hydroelectric facility|hydroelectric plant]] or [[water wheel]]. The water in this channel has already been used to rotate [[hydro turbine|turbine]] blades or the water wheel itself.</onlyinclude> This water has served its purpose, and leaves the [[power]] generation unit or water wheel area.<ref name="RE1">BrightHub Engineering. (August 28, 2015). ''Various Components of Hydroelectric Power Plants and their Working: Part-3'' [Online]. Available: http://www.brighthubengineering.com/fluid-mechanics-hydraulics/7122-components-of-hydroelectric-power-plants-part-three/</ref>

In [[hydroelectric dam]]s, the tail race is at a much lower level than the height of the [[hydroelectric reservoir|reservoir]] behind the [[hydroelectric dam|dam]]. This difference in height corresponds to the amount of [[hydropower]] that can be obtained from the water, and the height difference is known as the [[hydraulic head]]. This change in height corresponds to a change in [[gravitational potential energy]]. Some of the gravitational potential energy from the water above the dam was used to spin the turbines and [[electricity generation|generate electricity]]. Water flowing from a hydroelectric plant in the tail race eventually joins the natural flow of water.<ref name="RE1"/>

In water wheels, the tail race can be either at the same height as the [[mill race]] - in the case of [[water wheel#Undershot Wheel|undershot wheels]] - or at a lower height - in the case of [[water wheel#Breastshot Wheel|breastshot wheels]] and [[water wheel#Overshot Wheel|overshot wheels]].
