Abbey River

The Abbey River is a right-bank backwater of the River Thames in England, in Chertsey, Surrey — in the town's northern green and blue buffers. The L-shaped conduit adjoins mixed-use flood plain: water-meadows landscaped for a golf course, a motorway and a fresh water treatment works on the island it creates, Laleham Burway to its east and north in turn. Its offtake from the Thames is at the apex of Penton Hook, Staines upon Thames below its lower weir close to the Chertsey-Thorpe boundary in the Borough of Runnymede. Its outfall is the weir pool of Chertsey Lock back into the Thames, visible from Chertsey Bridge. The Environment Agency plans to build similar channels to the upstream Jubilee River, one of which will intersect the watercourse, another of which will be close to its outfall, thereby compensating for loss of its historic bypass functions.
The 3.2 km long river, which was also known as Oxley, Oxlake or Oaklake Mill River or Stream was a leat cut by order of the Abbot of Chertsey Abbey in the eleventh century to supply power to the mill closest to their monastery/abbey and water their numerous fish ponds.
