River Derwent

The Derbyshire Derwent was once navigable from Derby to its junction with the River Trent at Derwentmouth, a distance of 12.5 miles (20.1 km) and rights of navigation still exist on the river.  Derby and Sandiacre Canal Trust run a trip boat on the river in Derby.

Waterways notes

Navigation Authority

None – but the river is effectively controlled by the Environment Agency

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.
