The resvoirs to supply water
The greatest problem for the Burgundy Canal since its construction, has been to maintain an adequate supply of water necessary in operating the locks which allow the barges to cruise. Millions of tons are required each year. To accomplish this water is stored and supplied in different manners.
All the reservoirs are filled with the winter snows and rains, there are small "canals" supplying water from the reservoirs to the canal and are controlled by the local keepers. The water is sent from the reservoirs to the canal at critical times and in a regulated manner to assist in maintaining the required water levels.
The canal uses reservoirs, rivers and springs to accumulate and store water. Delivery of water depends on the altitude of the canal. Near the summit of the canal between Veneray, Pouilly and Crugey, the water is supplied by 5 reservoirs, Grosbois, Cercey, Panthier, Tillot and Chazilly.

Through the years the reservoirs have also developed their own "micro" ecological environments.
Grosbois reservoir
The most spectacular reservoir on the Burgundy canal is the reservoir of Grosbois. The dam of the reservoir was built in 1830 to 1838, and is 22.30 metres high, with a capacity of 9,220,000 cubic tonnes of water. In 1842, nine reinforcements where built giving the dam more stability. The dam is 530 metres long, and the surface area of the reservoir is 105 hectares. Due to lack of funding and upkeep the capacity has been reduced to 7,800,000 m3. There is also an additional part to the reservoir built in 1900 below the main dam. A supplementary earthen dam was built holding 820,000 m3 of water, in an attempt to increase water reserves for the canal. Further work on the dam in 1986 increased the capacity to 910,000 m3.
Cercey reservoir
Cercey reservoir has an earth dam of 1.02 km, built in 1834 and tool 2 years to finish, the capacity is 3,590,000 m3. Stone reinforcement were built in 1868 to prevent land slides, the reservoir covers 63 hectares.
Panthier reservoir
Panthier Reservoir
Panthier with an earth dam built in 1834 and is 7.60 metres high was enlarged in 1869 to 13.94 metres and holds 8,050,000 m3, it covers 120 heaters. The reservoir is below the summit of the canal at Escommes, and acts as an overflow in capturing water from the summit. The first "pound" that Panthier can supply is at lock 9 Saône. There is a large camp site that has grown at Panthier, sailing and fishing have also developed here.
Tillot reservoir
Tillot has a stone dam and reinforcements, it was built in 1830. The dam is 9.30 metres high and holds only 520,000 m3.
Chazilly reservoir
Chazilly is very similar to Grosbois, the stone dam being 22 metres high and a capacity of 5,190,000 m3 of water covering 52 hectares.
The dam wall of Chazilly is very impressive and reaches a height of 22.5 metres. Construction of the reservoir took 7 years from 1830 to 1837, by the engineer M Bonnetat.
Lac du pont
The Lac du pont, with it's granite wall was built in 1879 and captures water from the Armançon river. The reservoir holds 6,000,000 m3 of water, covering 80 heaters with a perimeter of 12,3 kilometres.
