The English River Thames is navigable from Cricklade or Lechlade to the sea, and this part of the river falls 71 meters (234 feet). There are 45 locks on the river, each with one or more adjacent weirs. These lock and weir combinations are used for controlling the flow of water down the river, most notably when there is a risk of flooding, and provide for navigation above the tideway.
The River Blackwater is a tributary of the River Loddon in England and, indirectly, of the River Thames. It rises at Rowhill Nature Reserve between Aldershot in Hampshire and Farnham in Surrey and runs northwards to join the Loddon near the village of Swallowfield in Berkshire. Along part of its length, the river forms the boundary between Hampshire and Surrey, and then between Hampshire and Berkshire. Rowhill Nature Reserve is an isolated remnant of the extensive heathland that once surrounded Farnborough and Aldershot. After 20 miles (32 km) the Blackwater is joined by the River Whitewater near Eversley. The river gives its name to the small town of Blackwater, Hampshire, upon the river near Camberley.

It was founded in 1857, initially replacing the jurisdiction of the City of London up to Staines and later taking responsibility for the whole river from Cricklade in Wiltshire to the sea at Yantlet Creek on the Isle of Grain. Responsibilities were reduced when the Tideway was transferred to the Port of London Authority in 1909 and in 1974 the Conservancy was taken into the Thames Water Authority.
