The race leading to the water wheel on a wide stream or mill pond is called the head race (or headrace [2]), and the race leading away from the wheel is called the tail race [3] (or tailrace [2]). A mill race has many geographically specific names, such as leat, [4] lade, flume, goit, penstock. These words all have more precise definitions and ...
Tailrace fishing at the Mansfield Dam, Texas. Hydro tailrace fishing is a more modern form of fishing the turbulent waters below reservoirs. The term hydro generation refers to the massive generators within a dam structure that are propelled by the force of gravity pushed by the vessel of water through an impeller which rotates the rotor causing lines of magnetic flux thus creating electric ...
The race bringing water from the mill pond to the water wheel is a headrace; the one carrying water after it has left the wheel is commonly referred to as a tailrace. [ 1 ] Waterwheels were used for various purposes from things such as agriculture to metallurgy in ancient civilizations spanning the Hellenistic Greek world , Rome , China and India .
The environmental conditions in a tailwater influence the entire food web of the waterway. Consistent flows, higher temperatures, and clear water found in tailwaters create an ideal habitat for filamentous green algae. [2]

Draft tube installed above tail race. A draft tube is a diverging tube fitted at the exit of a turbine's runner and used to utilize the kinetic energy available with water at the exit of the runner. [1] This draft tube at the end of the turbine increases the pressure of the exiting fluid at the expense of its velocity.
The length of most head races is usually between 4 km and 10 km. Among the most well-known are the 4.25-mile (6,840 m) Head of the River Race that takes place each March on the river Thames in London, United Kingdom, [1] the 3-mile (4,800 m) Head of the Charles race held each October on the Charles River in Boston, Massachusetts, United States., [2] and the 8 km Head of the Yarra race held ...
Draft tube: The draft tube is a conduit that connects the runner exit to the tail race where the water is discharged from the turbine. Its primary function is to reduce the velocity of discharged water to minimize the loss of kinetic energy at the outlet.
