Beginning of the Canal de Saint-Martory at Saint-Martory (on the right the Garonne)

The Canal de Saint-Martory is an irrigation canal in the Haute-Garonne department in the Occitanie region . It branches off from the Garonne at Saint-Martory on the left bank and runs as a side canal for a length of 71 kilometers to Toulouse , where it flows underground again into the Garonne in the urban area.

history

As early as the first half of the 19th century, plans were developed to artificially irrigate the Garonne plain. Other possible solutions even envisaged expanding a shipping canal under the name Canal des Pyrénées to the upper reaches of the Garonne. In the 1850s, when it was ready to be implemented, the expansion of the railroad had progressed so far that expanding the canal was no longer economically viable for shipping. In 1862, engineer de Raynal made the final design for the project. The canal was built from 1866 to 1876.
