Montady Lake was drained in 1247. The best viewpoint from which to admire it is the Ensérune hill fort. From the viewing tables, the plots of land radiating from the centre become obvious: this is due to the ditches draining the water off into a collector. From there, an aqueduct passing under a hill takes the water to the bottom of the old Capestang Lake, which was drained in the 19C. The panorama can be absolutely splendid, depending on the crops and time of year.
