Marker 1The Trabassac, which has cut deeply into the schist, has a low average rate of flow. But during storms it can abruptly go from being almost totally dry to a raging torrent. Then its capacity to erode is impressive! A water intake point built next to a small dam used to let water into a béal (or bésal in Occitan: irrigation channel), whose starting-point can still be distinguished. It directed the water to a mill (Point 2) built away from the banks so as to protect it from floods. The Mediterranean or southern barbel is a fish typically found in this stream, as is the brown trout.
