Where the data comes from
Waterwaze blends authority feeds with local knowledge — and shows the difference.
Canal & River Trust
Stoppages, navigation notices, facilities, moorings and network works across England and Wales.
Open notices ↗Environment Agency
River levels, flows, flood warnings and Thames / Anglian navigation information.
Open API reference ↗Scottish Canals
Works, closures, navigation restrictions and notices for Scotland’s five canals.
Open works ↗OpenStreetMap
Community-mapped locks, water points, sanitary dumps, fuel, moorings, marinas and boatyards.
View mapping guide ↗National Data Library
Published datasets such as locks and infrastructure that can seed the national network index.
Open dataset ↗Trust model: official notices can override community reports; records should carry a source, captured time, review time and confidence score.
Seen something change?
Waterwaze gets better when boaters share the detail: a stiff gate, a working tap, a new mooring rule. Every update carries a timestamp and community confidence.
