Summit-level canal

[1] Summit-level canals were an essential step in the extension of transport systems before the development of railways and modern highways.

It used fifteen staunches and had a 13-kilometre (8.1 mi) summit level; the millers only opened the flash locks on alternate days.

In many ways it is the ancestor of all modern summit-level canals being fed from its reservoir, Étang de la Gazonne.

[4] One of the greatest engineering feat of the 17th century was the Canal du Midi in Southern France opened in 1684, joining the Garonne, which drains into the Atlantic Ocean to the Étang de Thau which leads to the Mediterranean.
