Barrage (dam)

A barrage in Rockhampton, Australia
Marina Barrage, Singapore
Teesta Barrage at Gajoldoba in West Bengal, India.

A barrage is a type of low-head, diversion dam which consists of a number of large gates that can be opened or closed to control the amount of water passing through. This allows the structure to regulate and stabilize river water elevation upstream for use in irrigation and other systems. The gates are set between flanking piers which are responsible for supporting the water load of the pool created.

The term barrage is borrowed from the French word "barrer" meaning "to bar".[1]
