Many watermills lined the banks of the River Wey, England, from the 17th century, due to the river's ability to provide a reliable, year-round flow of water. These mills chiefly ground wheat, often referred to as corn, for flour and oats for animal feed though many were used in the production of other goods such as paper, cloth, leather, wire and gunpowder. The river was home to more mills per mile than anywhere else in Great Britain. The mill situated at Coxes Lock near Addlestone, Surrey, is the largest. There are many mills on the river's principal tributaries, such as the Tillingbourne and the Ock, as well as mills on the Whitmore Vale stream, Cranleigh Waters and Hodge Brook. The last commercial mill on the Tillingbourne, Botting's Mill at Albury, closed in 1991. Headley Water Mill, on the Wey South branch is still in business. Town Mill, Guildford still has a water turbine driven generator producing electricity for the town.

Note: The mills are listed from source to mouth for each waterway.
