Key for Restoration Maps

Map Key

Historic Line of Canal:
Line of waterway largely obliterated; built over or filled in, with little or no visible evidence of canal line remaining.
(Historic line may be shown where more specific information is not available).

Derelict Canal/Tunnel (dashed):
Line of waterway dry or filled in but evidence of route remains; gaps between buildings, bridges or bridge parapets visible at original crossings, path or depression in ground identifies historic route. Tunnel unlikely to be restored.

Disused Canal/Tunnel (dashed):
Line of waterway clearly evident and retaining some water although it may be heavily silted or overgrown. Not regularly used for any kind of navigation.

Isolated Section:

Canal in water and used for limited navigation but isolated from other parts of the waterway. May support a trip boat operation.

River Navigation (Abandoned):
Extent of lost river navigation.


Preferred route for new canal channel where use of historic line is no longer feasible or, completely new waterway planned. 


Navigable canals and rivers adjacent to the restoration.

Inclined Plane:
    Historic location of inclined plane.

The restoration maps on the IWA website are generated from the OpenStreetMap database. Tagging (historic, derelict, disused, etc.) is provided by OpenStreetMap contributors and is subjective, and may not be consistent across waterways. The maps and key should not be regarded as definitive.

The waterway route shown does not imply any right of way although many will be accessible by public footpaths. Check Ordnance Survey maps before visiting.
