TOPSHOT - Boats are seen in the dryed bed of the Brenet Lake (French: Lac des Brenets) part of the Doubs river, a natural border beetwen eastern France and western Switzerland, on September 20, 2018 in Les Brenets. - Upstream, the river has dried up in spite of abundant precipitation this winter and spring - a situation that is due to geological faults that empty the river, accented by a rainless summer.
