Netham Lock

Netham Lock (grid reference ST616727) is the point at Netham in Bristol at which boats from the River Avon, acting as part of the Kennet and Avon Canal, gain access to Bristol's Floating Harbour.

Construction started in 1804 to build the tidal New Cut and divert the River Avon along the Feeder Canal to the harbour; a system designed and built by William Jessop and later improved by Isambard Kingdom Brunel.

High tides often pass over the weir, and the river is effectively tidal to the next lock upstream at Hanham.

Some spring tides can also pass over the weir at Hanham, making the river tidal as far as Keynsham Lock.
