Hanham Lock

The Bristol Avon Navigation, which runs the 15 miles (24 km) from the Kennet and Avon Canal at Hanham Lock to the Bristol Channel at Avonmouth, was constructed between 1724 and 1727,[1] following legislation passed by Queen Anne,[2][3] by a company of proprietors and the engineer John Hore of Newbury.

It opened in 1727 and there used to be a colliery wharf just west of the lock, however the mines closed in the 19th century.

[5] The river below Hanham Lock is considered to be tidal, as high tides often pass over the weir at Netham.

Some spring tides will also pass over the weir here, making the river tidal up to Keynsham Lock.

[7] In front of this house once stood Hanham Mills, an archway over the towpath being all that remained of the mills until 1897, when the Hanham Abbotts Parish Church had the archway demolished due to its poor state of repair.
