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 pond covers an area of 2000 ha, and is shared between the municipalities of Marseillette, Aigues-Vives, Saint-Frichoux and Puichéric. In the past, it supplied the region with fish. From the 12th century onwards, people began to talk about draining this stagnant body of water, a source of death and misery for Marseillette and the surrounding villages, which were becoming depopulated. In 1605, Henry IV issued a royal decree to drain the Pond. But it wasn't until 1804 and the purchase of the Pond by an Irishwoman, Madame de Lawless, that it was drained, thanks to a vast construction project. The pond was then cultivated and developed to use the waters of the Aude, with an original irrigation system consisting of perpendicular canals allowing the flooding of the land. Today, vines, apples, and rice are the main products found there. Its quiet and flat paths are very pleasant for hiking or cycling, in a typical landscape.
