Restoring the Old Stratford Arm

Leaving the Grand Union Canal at Cosgrove, a short stretch of the Old Stratford Arm is used for moorings.  The aim is to restore the Old Stratford Arm and its extension, the Buckingham Arm, through to the town of Buckingham.

A Halcrow engineering study found the project to be feasible, though with significant issues to address such as crossing the A5 dual carriageway. Possible solutions have been identified. Four sites are currently being worked by Buckingham Canal Society volunteers.  So far a traditional stone bridge has been restored, a lock is under restoration and a length of canal near Buckingham has been re-watered.  The Society has developed partnerships with local authorities and there is increasing local public awareness.

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.
