Big River Watch Data Explorer

Find out what Big River Watch-ers recorded in their river health surveys in the UK and Ireland.

Twice a year, we hold Big River Watch events. Over the course of a week, we encourage members of the public to download our free app, visit their local river, and spend a few moments recording what they see and how they feel.

Use the dashboard below to explore the data sent in across the UK and Ireland, in the May 2024 and September 2023 Big River Watches.

The map below works best on desktop or tablet. Exploring on mobile? Click here for the full-screen data dashboard.
