A 36 mile path from Millmead Lock, Guildford to Amberley in West Sussex. The Path follows the towpath of the Godalming Navigation along the River Wey to its confluence with the Wey & Arun Junction Canal, crossing the North Downs Way National Trail near the start. Wherever possible the route follows the towpath, supplemented by paths, roads and disused railway (Downs Link), to reach and continue beside the Arun Navigation to the River Arun whence the path continues to meet the South Downs Way National Trail above Amberley. Several sections of the canals have been restored. The canals were originally built for military purposes to provide a waterway linking the Thames and the south coast, but were soon supplanted by the railways and some sections fell into disrepair.
TQ0317 : Hardham pumping station with Geese flying south The weird machine does what you supposed - it lifts debris from the river intake (the tank) and drops it back into the river. It generally only has anything to pick up after high flows, but it runs on a timer.
