Sivens Dam (Barrage de Sivens) 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 (6.2 mi) north of Lisle-sur-Tarn, in the Department of Tarn (Midi-Pyrénées). The dam was named after the nearby Forest of Sivens.

The project would have created a reservoir, with a volume of 1,500,000 m³ (53,000,000 cu ft), that could have been utilized to irrigate local farmland and control low water levels in the river Tescou. The ecological footprint of the project would have resulted in the destruction of 12.7 ha of wetland (18.1 ha in total, taking into account indirect destruction of wetlands by overall loss of functionality)^[1]. As a result, the project planned a compensatory restoration of land that totaled 19.5 ha in area.

Construction work began in 2014, under the CACG, and was then halted after Rémi Fraisse, a 21-year-old man protesting against the construction project, was killed by a OF-F1 Grenade fired by police^[2]. His death was a part of the demonstrations against the dam on October 26, 2014, which sparked further protests across France, some of which were violent.^[3] The project was then closed in 2015 by the Minister of Ecology Ségolène Royal.^[4][5]

The Minister of Ecology requested a project assessment report in January 2016. In July 2016, the Toulouse administrative court annulled the three original purposes of the dam project, in particular the declaration of public utility.
