The Calavon, a torrential river

When you cross the big bridge of La Blaque, lean towards the Calavon's riverbed, which is most of the time dry or almost dry. But do not be fooled by its quiet appearance. The Calavon is a monster that sleeps! Its large watershed can produce deadly flooding downstream. Notice the early warning system located at the end of the bridge (limnigraph with solar power batteries that can record changes in water level).
