History and Technology of Watermills

30 · Rural water mills began to close down to be replaced by the large, industrial, port-based steam-powered mill and by the end of the 19th Century almost all rural watermills had ceased commercial production. How Mills Work. Water mills use the flow of water to turn a large waterwheel. 26 · Typically, water is diverted from a river or impoundment or mill pond to a turbine or water wheel, along a channel or pipe (variously known as a flume, head race, mill race, leat, leet, lade (Scots) or penstock). The force of the water's movement drives the blades of a wheel or turbine, which in turn rotates an axle that drives the mill's other machinery.
