The Big River Watch 2023

Wild Marlow currently has a surveying project running, monitoring and collecting valuable data at various watercourse locations in the area including the Thames.
The Rivers Trust has a really useful app you can download, to help log sightings and contribute to the data gathering.
You can log the things that you see – from wildlife and plants, to the flow speed of the water and whether you can spot any pollution. If you don’t know what you’re looking at, there’s a handy in-app ID guide for pollution and wildlife.
Whether you’re a swimmer or a paddler, an angler or a rambler, a wildlife spotter or a sit-and-watch-er, this is a chance to be part of a citizen science project to improve our freshwater spaces.
