The next lock is Compton Lock, the only one built on a river section. It is also called Compton Place Lock or Twyford Lock, and the extra flow compared to other locks may explain the erosion that has taken place, resulting in a circular area of water between the upper and lower gates. Just above Shawford Bridge, the river and navigation diverged, with Shawford Mill just below the junction. The building still stands. The bridge is a modern construction, and is located at a point where the towpath crosses to the western bank. Just to the south is a weir at the site of Shawford Single Gates, which probably ensured the mill had an adequate head of water. The village of Twyford lies to the east, and the Twyford Drain splits, with the western channel rejoining the river below the mill, and the eastern channel continuing as a relief channel. There are two more locks on the navigation, called Malm Lock and College Mead Lock, before the navigation rejoins the river. By the junction is the intake for Otterbourne Water Treatment Works.
