Will you see pollution or wildlife? Take part in the Big River Watch and help survey your river: 24th-30th April 2026
Our beautiful and vital rivers are in crisis, and every bit of data about their health helps organisations better plan how to restore and protect them.
The Rivers Trust’s Big River Watch is your invitation to love your local stretch of river and stand up for wildlife. To play your part as a citizen scientist, simply download the free Big River Watch app (available in English and Welsh), spend 15 minutes by a river between the 24th-30th April, and complete the short survey to record what you see – from wildlife and water colour to pollution.
Your response will be part of a UK and Ireland-wide dataset that can be used to fight for cleaner rivers. Learn more: The Big River Watch | The Rivers Trust
