A fisher heard a gurgling sound this morning while he was fishing in the Risle. Then the Risle was gone, under the ground for a length of 8 kilometres. This phenomenon is called ponor. The problem is, that the fish die and the quality of the water will go underground too, while we don’t have very good drinking water now, it might be just terrible in near future. The place of the ponor is between La Houssaye und Ferrières-sur-Risle, 32 Kilometer south of here. I just had to drive there and take some photos, with a free licence. But it turned out, that the place is much more dangerous than I thought it would be, so don’t go there. Do not attempt!
