London's River Thames has shrunk as extreme heat and looming drought dries up its headwaters
London (CNN) The starting point of England's famous River Thames has dried up and moved downstream, following weeks of little rainfall and a heat wave in July that smashed the UK's all-time temperature record.
The Thames usually begins in the English market town of Cirencester, part of the green and hilly Cotswolds countryside, and flows through the capital, London, and then out into the North Sea.
The start of the river has moved 5 miles (8 kilometers) downstream to Somerford Keynes, according to the Rivers Trust, which works across the UK and Ireland.
The flow there is weak and only just discernible.
"What we're seeing at the source of the iconic River Thames is sadly emblematic of the situation we're facing across the country, now and in future," Christine Colvin, Advocacy and Engagement Director for the Rivers Trust, said in a statement sent to CNN.
