• The canal between Champagne and Burgundy

• The canal between Champagne and Burgundy (from the Marne to the Saône) is like the backbone of Haute-Marne. Its realization began in 1862, after a study undertaken between 1839 and 1845. The entire course was completed on February 1, 1907 for a total length of nearly 225 kilometers, including 166 in Haute-Marne. Between the Marne basin and the Saône basin, the threshold of the Langres plateau, the watershed, is crossed by means of a 4.8-kilometer tunnel (the 4th fluvial tunnel in France). It was dug out 118 meters underground and dug between 1882 and 1888. It is 8 meters wide and has a 4-meter high arch. Its route passes just under the village of Balesmes-sur-Marne. The Langres plateau, the highest point of the canal, also required the setting up of 18 locks between the Côte d'Or and Foulain. On the other hand, its higher altitude offered also the best possibility of water supply by gravity. The presence of numerous sources has thus enabled the engineers to guarantee this supply by the construction of 4 reservoir lakes responsible for regulating the level of the canal. Today, with the use of barges, river tourism has been added: another way to apprehend the charms and tranquility of the canal, from the port of Champigny-lès-Langres.

• Its waters occupy the bottom of a deep valley of the Langres plateau. This biotope is characterized by a fluvial type of dynamics: the water level, very variable according to the seasons according to the needs in water of the channel, is notably quite low in the end of summer and in autumn. These special conditions favor a special vegetation, stabilized for a long time with very typical vegetation belts.
