We use live river level data from the environment agency and combine it with research from happyhiker.co.uk to work out if the stepping stones are crossable.
Rivers are fascinating yet unpredictable, and our crossing guide is just an estimate. Shifting riverbeds, sluice gate operations, and numerous other factors make it impossible for us to guarantee that our cross-o-meter is always accurate!
The river level data is environment agency flood and river level data from the real-time data API (Beta).
