The Big River Watch is returning. From 6th to 12th September, the South East Rivers Trust is inviting people across the South East to join the only UK and Ireland-wide citizen science survey of river health, which has attracted more than 9,000 participants in its first year. 

Anyone can join the Big River Watch by downloading the free, easy-to-use app and spending 15 minutes by their local river, answering the simple survey questions. The results will be made available on an interactive dashboard and will help drive action to improve rivers both on-the-ground and via campaigns and political advocacy. 

We want to build a complete picture of river health, and topics covered include the plants and wildlife people can see, as well as visible signs of pollution or observations on flow levels. Some of the rivers and chalk streams across South East England provide habitats for rare species such as Beavers, Otters, Nightingales, Turtle Doves, Salmon and Brown Trout. It’s essential that we try and restore healthy ecosystems for these rare species and local communities by carefully monitoring the health of the waterways across the region.

The South East Rivers Trust is running a series of volunteer events across the South East throughout September, including river clean-ups, gravel seeding and planting, where local communities can get involved and help restore their river: www.southeastriverstrust.org/events

Bella Davies, CEO at The South East Rivers Trust, said: “People across the UK and Ireland are becoming more and more interested in the health of their rivers, using their voices – and their votes – to show they care. With the Big River Watch, anyone can get involved in monitoring signs of pollution, spotting wildlife, and sharing their connection with their local river. This isn’t just important for us gathering data but is also empowering for people who are demanding better for our rivers.” 

Tessa Wardley, Director of Communication & Advocacy at The Rivers Trust, said: “We know that no rivers in England are in good overall health, but we also know that environmental monitoring is currently very sparse. Having a large set of data from one weekend will help our experts to understand what’s going on in our rivers, and what needs to be done to make them cleaner, healthier, and part of a thriving wider environment. As well as learning where pollution and wildlife are spotted, we also want to know how spending time near rivers affects people’s wellbeing, so I’d encourage anyone and everyone to spend some time by their river and make their voice heard.” 

  • The survey includes questions on river wildlife, signs of pollution, and health and wellbeing 
  • Results will be updated in near-real time on the Big River Watch Data Dashboard 
  • More than 9,000 people have now taken part in the Big River Watch, 59% of those being new to citizen science
