Abbey River

Abbey River north of the Abbey site

The Abbey River is a backwater of the River Thames, near Chertsey, Surrey. It runs from behind Penton Hook Island to below Chertsey Lock.

The river, which was also known as Oxley Mill River was probably cut by the monks of Chertsey Abbey in the eleventh century to supply their mill. In 1608 there were two watermills on the river known as the Oaklake Mylles. In 1809 the millers offered the stream as the main navigation channel but the Corporation of London had already decided to build the lock at Chertsey.
