The River Weaver Navigation runs from the Manchester Ship Canal at Weston Marsh Lock and Weston Point Docks to Winsford Bridge and connects to the Trent and Mersey Canal via Anderton Boat Lift. The River Weaver Navigation is 20 miles (32 km) long and has 5 locks.
The maximum size of boat that navigate throughout the Navigation is
length: 196' (58.8 metres)
beam: 35' (10.6 metres)
height: 29' 6" (8.9 metres)
draught: 9' 10" (3.0 metres)
The maximum size of boat that can travel on Anderton Boat Lift is
length: 72' (21.6 metres)
beam: 14' (4.2 metres)
height: 8' (2.4 metres)
draught: 4' (1.2 metres)
Locks, swing bridges and Anderton Boat Lift are all operated by Canal & River Trust staff.
Navigation above Winsford Bridge and into Winsford Flash is possible, where there is no navigating authority. The Flash, especially, is very shallow in places and there is a significant risk of boats becoming stuck in the silt.
