The Big River Watch starts today! Download the survey app to your phone, head to your local river and record the wildlife you can see. If you find it harder to reach the riverside, is supporting Thames21 to set up trail cameras in locations on the River Thames near Goring, to enable everyone to take part. More will be revealed next week!

🌊 The Big River Watch is back!
📅 Save the date and tell your community.
From 18–24 September, we’re asking anyone and everyone to visit their local river and spend just 15 minutes recording what you see.
It’s free, it’s easy, and your observations can make a real difference. 💙
📱 Simply:
1️⃣ Search 'Big River Watch' in your app store and then download the Big River Watch app
2️⃣ Visit your local river
3️⃣ Spend 15 minutes observing and recording what you see
4️⃣ Upload your findings
From plants and wildlife to water colour, litter and signs of pollution, every observation helps build a bigger picture of the health of our rivers across the UK and Ireland. 💧🌿
The data helps us and the wider Rivers Trust movement call for change and demand better for our rivers.
And because the data is open to everyone, you can explore previous years’ results too, helping you see what’s happening in your patch and highlight what’s good, and what needs attention. 🔎
