The pretty Walsham Lock and Weir have a scenic setting 1 km north of the village of Ripley in Surrey. The lock has several notable features and is surrounded by tranquil and picturesque flood meadows and by Pyrford Golf Club. These attributes make it well worth a visit.
Walsham is the last surviving turf-sided lock on the Wey Navigation. This means that it operates as a flood lock and has its lock gates always open unless the River Wey is in flood. If there is a flood the lock gates are closed to force water over the nearby Walsham Weir and down along the River Wey.
Two further unusual features of Walsham Lock are first that it’s situated on a slight bend such that its top and bottom lock gates do not quite align with each other. Second, its adjacent pleasant lock-keeper cottage is the last remaining fully-manned lock cottage on the Wey Navigation. The original lock-keeper cottage was built in 1653 and the current one dates from 1896.
The Walsham Weir and its roaring water marks where the River Wey Navigation separates from the River Wey. The two waterways do not rejoin again downstream until Weybridge. The Walsham Weir is the main Weir on the Wey Navigation downstream of Guildford.
When crossing the former horse bridge over the River Wey by the Weir you should look out for the entrance to a naturalised fish and eel pass channel route. This 170 m long channel has a reduced water flow compared to the Wier so that fish and eels can make their way upstream on the River Wey.
