High Quality Content by WIKIPEDIA articles! Man has used the Medway, its tributaries and sub-tributaries for over 1,150 years as a source of power. There are over two hundred sites where the use of water power is known. Many different processes were performed by the use of water power:- Corn milling, fulling, paper making, iron smelting, pumping water, making gunpowder, vegetable oil extraction and electricity generation. Today, there is just one watermill working for trade. Those that remain have mostly been converted. Such conversions include a garage, dwellings, restaurants, museums and a wedding venue. Some watermills are mere derelict shells, lower walls or lesser remains. Of the majority, there is nothing to be seen. A large number of tributaries feed into the River Medway. The tributaries that powered watermills will be described in the order that they feed in. The mills are described in order from source to mouth. Left bank and right bank are referred to as though the reader is facing downstream. This article deals with the watermills on the tributaries that feed in below Yalding.
