Description
editThe idea of constructing a dam on the Rougeanne River dates back to the 18th century with the aim of improving the water supply for the Canal du Midi. Pierre-Paul Riquet, the designer of the canal, had envisioned building a water reservoir to better supply water to his creation through the Alzeau intake. However, it wasn't until 1985, during severe water shortages, that the project was considered. The construction was declared of public utility and general interest by decree on June 24, 1998. The La Galaube Dam itself was built from 1999 to 2001 at an altitude of 720m by the "Institution interdépartementale pour l'aménagement hydraulique de la Montagne Noire" (IIAHMN), established in 1948 among the departments of Aude, Haute Garonne, and Tarn.[1][2] With a cost of 100 million francs, it supplies drinking water to several departments (Aude, Tarn, Haute-Garonne). It regulates the flow of the Montagne rigole and transfers water to the Camazes reservoir.
The La Galaube Dam is 43 meters high rockfill dam sealed with a bituminous geomembrane protected by cast-in-place concrete. Its core is constructed using micaschist rock and spans over 400 meters. Various monitoring devices, such as piezometers and tacheometers, ensure the dam's ongoing safety and performance.[3][4]
