Shifford Lock

About

Shifford Lock is a lock on the River Thames in England. It is in the centre of a triangle formed by the small villages of Shifford, Duxford and Chimney in Oxfordshire. It is at the start of a navigation cut built with the lock by the Thames Conservancy in 1898.

This was the only new lock built on the non-tidal Thames in the era of falling revenue after the Thames Conservancy took over responsibilities of the Thames Navigation Commission. It replaced a flash lock in a weir about 3⁄4 mile (1.2 km) downstream. There is a small weir beside the lock and a larger weir on the old course of the river upstream at the top of the lock cut.
