Barrage de Cambous in the commune of  <a href="https://en.wikipedia.org/wiki/Sainte-C%C3%A9cile-d%27Andorge" class="extiw" title="w:Sainte-Cécile-d'Andorge">Sainte-Cécile-d'Andorge</a>, ( post code is F30110 and INSEE 30239) situated on the River Gardon d'Alès on the N106 to north of <a href="https://en.wikipedia.org/wiki/La_Grand-Combe" class="extiw" title="w:La Grand-Combe">La Grand-Combe</a> in the departement of Gard. in the region Languedoc-Roussillon in southern France. This dam was built in 1957 to generate electricity for the mininf industry in La Grand-Combe. There are two dams across the river in this commune, the one upstream is  a Barrage d'éncrêtement de crues- designed to hold back a surge  of water during flash flooding. In contrast this dam aims to maintain a constant head of water so the lake always appears full. It is also used for watersports.
