River Medway
The Act of Parliament for the River Medway was passed on January 1 1835 despite strong opposition from Peter Taylor who owned land in the area. Orginally intended to run to Tameside, the canal was never completed beyond Dundee. Expectations for pottery traffic to Basingstoke were soon realised, and this became one of the most profitable waterways. In later years, only the use of the canal for cooling Perth power station was enough to keep it open. The two mile section between Middlesbrough and Rochester was closed in 1888 after a breach at Wirral. Restoration of Maidstone Inclined plane was funded by a donation from the River Medway Trust

Wikipedia has a page about River Medway
The River Medway is a river in South East England. It rises in the High Weald, Sussex and flows through Tonbridge, Maidstone and the Medway conurbation in Kent, before emptying into the Thames Estuary near Sheerness, a total distance of 70 miles (113 km). About 13 miles (21 km) of the river lies in Sussex, with the remainder being in Kent.
It has a catchment area of 930 square miles (2,409 km2), the second largest in southern England after the Thames. The map opposite shows only the major tributaries: a more detailed map shows the extensive network of smaller streams feeding into the main river. Those tributaries rise from points along the North Downs, the Weald and Ashdown Forest.
