The Thames has undergone an extensive recovery programme that has seen it go from a biologically dead river in the 1950s to today’s thriving waterway; teeming with fish, and with returning salmon, otter and sea trout populations.
Water quality has also improved, with rivers in the Thames catchment rising from 53% rated chemically “Good” or “Very Good” in 1990 to 80% in 2008.
Alastair Driver, the Environment Agency‘s national conservation manager, said: “In the last 150 years the Thames has been to hell and back, and it has taken thousands of people many decades to restore it to this point. … [Now] we and all of the people and organisations we work with are [are working to] ensure that the Thames remains an iconic river for many centuries to come.”
