It supplies 200 municipalities, representing over 170,000 inhabitants. The surface area of the body of water is approximately 90 hectares. Its reservoir volume is 18.8 million cubic meters; the watershed area is 30 km². The operator is the Montagne Noire Water Institution. The water is piped to the Picotalen treatment plant. It also serves as a reserve for the Canal du Midi via a water intake feeding the mountain channel (water rights of 4 million cubic meters) (Wikipedia)
