Instagram-famous lake on Swiss border left empty by brutal heatwaves

A lake that is famed for it’s beauty, often starring in touristsInstagram snaps, has been left almost drained by a prolonged drought across Europe.

Lake Brenets, a winding lake on the Swiss-French border, is normally packed with campers, swimmers and canoeists in the summer.

Boat companies also ferry thousands of tourists across it ⁠each summer season, but not this year.

The lake has been left ​virtually ⁠deserted as water levels in the River Doubs, which feeds it, have fallen sharply following months of scant rainfall and three successive heatwaves, ⁠the latest of which is still under way.

Dozens of boats are stranded high ​and ⁠dry on the cracked mud, including "Jumbo", ‌a tourist vessel operated by Yvan Durig, owner of the Societe de Navigation des Brenets.

"It's hitting us hard because we're powerless in the face of this ‌phenomenon," he said.

Already, he has had ‌to lay off his team and is concerned about making a loss for the year, with water levels now more than 9 metres (30 feet) below average and falling by around 22 centimetres (9 inches) ⁠a day.

With rainfall about half of the usual levels since April, the MeteoSuisse weather agency says this year's drought is comparable to some of the country's worst in 1976, 2003 and 2018. Its long-term forecasts suggest below-normal rainfall will continue until mid-August.

While the lake has experienced droughts in the past that have hit business, Durig said that their frequency has increased.

"These droughts are occurring in rapid ‌succession, something we've never seen before," he said.

The lake's remaining water ​is brown and reduced to a thin central ribbon, where fish ‌are now confined and a couple ⁠of swans paddle. A nearby waterfall that flows out of the ⁠lake, the Saut de Doubs, has virtually dried up, residents say.

“It’s so beautiful when there’s water, when ‌it’s flowing. It’s an ​idyllic, wonderful place," said Martial Beyeler, ‌a 69-year-old resident. "It makes me sad to ​see the place like this.”
