Northmoor Lock, Navigation lock on the River Thames in Oxfordshire, England
Northmoor Lock is a navigation lock on the River Thames in Oxfordshire that controls water flow along this section of the river. The facility consists of the lock chamber and an adjacent weir that work together to manage water levels.
The lock was built in 1896 by the Thames Conservancy to replace an earlier flash lock at Hart's Weir located upstream. Its construction was part of 19th-century efforts to modernize the Thames lock system.
The lock forms an integral part of the Thames Path, a National Trail that follows the entire length of the River Thames through the English countryside
Access is best via the Thames Path, the walking route that runs along the entire river. The route passes through open countryside, so visitors should be prepared for changing weather and wear sturdy shoes.
The adjacent weir features one of the last remaining manual paddle and lever systems for water control still operating on the Thames. This historic mechanical design offers visitors a glimpse into how river navigation was managed in earlier times.
