Thames21 is inviting people to work off the Christmas excess and help rivers at the same time by volunteering at a river clean up. Click here to see the calendar of projects.
They are also running their own free accredited training, if you want to run your own clean-ups or just learn more about our rivers! Click here to find out more and to book. The next course, which is 2 days, is on 19 and 26 January.
