Sivens Dam is an abandoned dam project, which was planned to cross the Tescou, a tributary of the Tarn in the basin of the Garonne, in Southern France, near Toulouse. The initial project was abandoned on December 4, 2015, by prefectoral degree. The construction site was 10 km north of Lisle-sur-Tarn, in the Department of Tarn. The dam was named after the nearby Forest of Sivens. From Wikipedia
