History

The river originally passed close to Sutton Courtenay and under a large mill there. In 1667 occurs the first reference to a pound lock underneath this mill. This had a set of gates beneath the mill floor and included a wide pool at the back of the mill. Consequently it required a very large volume of water to fill it and so incurred a heavy toll. There were complaints to the Thames Navigation Commission

 in 1772 that the floor of the mill was a great obstruction to navigation. Although it was privately owned, the Commission undertook some improvements in 1789, but complaints persisted on the grounds of inconvenience and high tolls. Finally the Commission's surveyor recommended the new lock with its long cut, and this was completed in 1809. A lock cut bridge was built at the same time.

Reach above the lock

The river follows the cut and turns sharply to the right when it rejoins the main course. A new junction for the Wilts & Berks Canal has been constructed almost opposite the top end of Culham Cut as part of a restoration project. The junction was opened on 30 August 2006, and initially runs for about 150 yd (137m) to a winding hole, but will eventually link to the historic route of the canal to the west of Abingdon.
