Shalford, Surrey in the context of Gordon Murray Automotive

The River Wey is a main tributary of the River Thames in south east England. Its two branches, one of which rises near Alton in Hampshire and the other in West Sussex to the south of Haslemere, join at Tilford in Surrey. Once combined, the flow is eastwards then northwards via Godalming and Guildford to meet the Thames at Weybridge. Downstream the river forms the backdrop to Newark Priory and Brooklands. The Wey and Godalming Navigations were built in the 17th and 18th centuries, to create a navigable route from Godalming to the Thames.

The Wey drains much of south west Surrey (as well as parts of east Hampshire and the north of West Sussex) and has a total catchment area of 904 square kilometres (350 sq mi). Although it is the longest tributary of the Thames (if the Medway is excluded), its total average discharge is lower than that of the Kennet and Cherwell. The river morphology and biodiversity of the Wey are well studied, with many places to take samples and record data. The main tributary is the Tillingbourne, which rises on the western slopes of Leith Hill and flows westwards to join the Wey to the south of Guildford, between Shalford and Peasmarsh.

The River Wey Navigation and Godalming Navigation together provide a 20-mile (32 km) continuous navigable route from the River Thames near Weybridge via Guildford to Godalming (commonly called the Wey Navigation). Both waterways are in Surrey and are owned by the National Trust. The River Wey Navigation connects to the Basingstoke Canal at West Byfleet, and the Godalming Navigation to the Wey and Arun Canal near Shalford. The navigations consist of both man-made canal cuts and adapted (dredged and straightened) parts of the River Wey.

The Wey was one of the first rivers in England to be made navigable; the River Wey Navigation opened in 1653, with 12 locks between Weybridge and Guildford, and the Godalming Navigation, with a further four locks, was completed in 1764. Commercial traffic ceased as late as 1983 and the Wey Navigation and the Godalming Navigation were donated to the National Trust in 1964 and 1968 respectively.

The River Tillingbourne (also known as the Tilling Bourne) runs along the south side of the North Downs and joins the River Wey at Shalford. Its source is a mile south of Tilling Springs to the north of Leith Hill at grid reference TQ143437 and it runs through Friday Street, Abinger Hammer, Gomshall, Shere, Albury, Chilworth and Shalford. The source is a semi-natural uninhabited area. The catchment is situated on sandstone which has a low rate of weathering. The Tillingbourne is 24 km (15 mi) in length.
