The river Bramont

There are actually two Bramonts! The one that you are cycling along, and another Bramont, which flows north of the Cham des Bondons. As you go through Les Combettes, you are at the foot of this limestone plateau, whose highest point is at about 1,200 m. But under the plateau flows another river: the underground Bramont, discovered in 1967. It takes some of the water of the Bramont du Lot (north) and empties it into the Bramont du Tarn (south)! The old-timers knew this and understood that by blocking, unblocking or diverting the waters draining out of the northern river, they could vary the rate of flow of the resurgence.
