Struncheon Hill Lock

Struncheon Hill Lock was built as a later addition to the Driffield Navigation in the East Riding of Yorkshire, England.

It improved access to the next section of water during low tide conditions where the navigation meets the tidal River Hull.

During the navigation improvements of 1803–1811, a new lock cut was made to bypass a large meandering loop of the River Hull around Struncheon Hill.

This is a standard known for Yorkshire Keels, however on further investigation it seems the lock was built to longer dimensions and in 2009 Michael Askin took a Royalty Class Narrow Boat Victoria of 71.5 feet (21.8 m) in length through the lock – though the boat would only fit pointing upstream due to low water levels not allowing enough depth over the top cill.

Just below the lock a steam powered pumping station was built to lift drain water to the river.
