The length of the Sussex Ouse that was once navigable.  Currently 4.7 miles (7.5 km) is still navigable from the sea at Newhaven Harbour Mouth.

From Sussex to Newhaven

The River Ouse flows through the heart of Sussex and out to the English Channel at Newhaven. 

Sussex Ouse Restoration Trust aims to preserve the historical structures along the river and hopes to restore the river to navigation in suitable places.  Sutton Hall Lock at Isfield has been largely restored, but has no gates. 

Waterway underfunding

Hundreds of miles of waterways – along with their unique heritage and habitats – are currently starved of funding and rely on constant lobbying by us to safeguard their future.

Sustainable Boating

We want boating on canals and rivers to be more sustainable and – even though the current overall contribution to UK carbon emissions is very small – we want to help reduce emissions on the waterways.

Waterways Heritage at Risk

Britain’s canals and rivers are a unique, living heritage. But that heritage is at risk – from urban development, lack of protection, loss of skills and knowledge and climate change.

You can help Save Waterways Heritage.

Waterway restoration

Restoring the UK’s blue infrastructure – our inherited network of navigable canals and rivers – is good for people and places.
