London’s Thames River shrinks as extreme heat dries up its headwaters

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 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.

“Whilst it’s not uncommon for the source to be dry in the summer, to only be seeing the river flowing five miles downstream is unprecedented,” she said.

“The climate crisis is leading, and will lead, to more extreme weather including droughts and heatwaves. This poses a grave threat to rivers and, as a result, the wider landscape.”

She added that the country needed to build resilience against the future climate.

“This means detecting household leaks, fixing mains infrastructure leaks, more efficient water use domestically plus implementing sustainable drainage solutions as part of desperately needed green infrastructure,” Colvin said.

The shift in the river’s headwaters comes as authorities in England warn that the nation could officially fall into drought at some point in August.

Southern England recorded its driest July on record since 1836, with only 17% of average rainfall, according to the Met office. The country as a whole recorded just 35% of its average rainfall in July.

Several water companies have already announced hosepipe bans in parts of England’s south.

The UK’s Met Office has warned that high temperatures will return to England next week, though they are not expected to reach near the record highs seen in July.

It said in a statement that an area of high pressure was building from the Atlantic into the south and southwest of England, and that temperatures could reach the low to mid 30s, in degrees Celsius, toward the end of next week.
