The best MTB trails around Montirat

A classic overflow weir is a "drain plug" or a weir that serves to drain excess water from the canal (during heavy rains or thunderstorms) to prevent the water from submerging the dikes.

The Trèbes locks are a flight of locks composed of three basins. Built around 1674, it is located downstream from the port of Trèbes at the exit of the town in the direction of the village of Marseillette. Taking advantage of the significant drop in the flight of locks, intense milling activity was established on the left bank of the lock. A first upper mill was built at the end of the 17th century. It is crossed by a diversion of the Canal du Midi which ensures its operation; it is described as having four millstones with a stable and a shed. A transformation of this first mill was carried out in 1867 to make it a mill with 6 millstones. This new building, later enlarged in the 1930s, consists of a basement and 4 floors at its highest point. It has today been converted into a restaurant.

The Canal du Midi, formerly the Royal Canal, is a 17th-century technical feat designed by Pierre-Paul Riquet to connect the Atlantic to the Mediterranean. Today, it is above all a place for relaxation and discovery, where heritage, nature, and conviviality blend together.

Tour du lac de Cavayère: a hilly 5km loop, ideal for working on your sprints

During the canal's construction, Pierre-Paul Riquet allowed streams to flow into the canal. Excess water was discharged through weirs. This system generated alluvial deposits that silted up the canal and disrupted navigation. By 1685, boats were having difficulty navigating in many places. In 1686, King Louis XIV entrusted Vauban with an inspection of the Canal du Midi (then called the Royal Canal of Languedoc). This aqueduct has three arches. At low water levels, the Orbiel River flows only under the western arch. During floods, it overflows its banks, and sometimes the three arches are no longer sufficient to maintain the flow. In the most severe floods, the structure can be completely submerged, as was the case in 2018.
