Thames21: River Thames and waterways in Greater London (UK)

Thames21 aims to improve London’s waterways for people and wildlife, using a volunteer force of over 9000 to ‘clean and green’ the capital’s 400 mile network of waterways. It also runs focused campaigns on particular stretches of waterways or ponds/lakes. A major campaign in 2012 was the Big Waterways Clean-up 2012, in preparation for the London Olympics.
