The River Ouse is 23 miles (37 km) long, (a former river navigation) flows through the heart of Sussex and out to the English Channel at Newhaven. The river had 19 locks.
The Sussex Ouse Restoration Trust seeks to preserve the historical structures along the once navigable river for future generations and hopes to restore the river to navigation in suitable places.
Restoration work is well advanced at Sutton Hall Lock at Isfield. The accumulated silt of 150 years has been removed and the lock chamber, culverts and associated wharf wall are being carefully restored. Initial clearance work has also taken place at Iron Gate Lock, in the grounds of Sheffield Park (National Trust).
