Source of Britain's River Thames driest ever as drought is declared

LONDON (REUTERS) - The source of the River Thames has dried up further downstream than ever before, as England enters a drought that some experts say the country is unprepared for.

Britain's Met Office said this July was the driest for England since 1935, with average rainfall, at 23.1mm, just 35 per cent of the average for the month. Some parts of the country saw the driest July ever.

The River Thames stretches 356km across southern England, from Gloucestershire in the west through the heart of London, before entering the sea at Essex to the east.

The natural spring that supplies the river, known as the source, dries up most summers. But this year, the dry riverbed reaches significantly further downstream than in previous years, according to observations by conservation experts.

"The Thames would normally be at its source - and there's a nice pub next to it - would be about 15km back upstream," Mr Alisdair Naulls, an engagement officer at the Rivers Trust, told Reuters while standing in a small section of the Thames in Cricklade, about 80km west of London.

"It's very, very shallow here… but you don't have to go much further up this little bit of the Thames to find yourself on dry ground. And really, that is ground that should still be wet and should always be wet," he said.

Mr Naulls said the shallow, warmer water contained less oxygen, which fish and other wildlife needed to thrive.

The Thames Head Inn lies upstream, a few steps from a stone that marks the source of the river in Gloucestershire. Its manager, 31-year-old David McMeeking, said he was concerned about the effects of climate change on the pub's namesake.

"It is still the official source of the Thames, so the stone will always be there. But whether or not the water comes through is another issue," said Mr McMeeking, while pouring a pint behind the bar.
