Main functions of Dujiangyan fish mouth

The main function of Dujiangyan fish mouth is to divert the Neijiang River from the Waijiang River, so that the river can flow down the river in the rainy season and merge into the Waijiang River. In dry season, reserve enough water to flow into Neijiang.

Yu Zui diversion levee is a diversion project of Dujiangyan. Named for its fish mouth. It stands high in the middle of the Minjiang River and divides it into two rivers. Xiwai River, commonly known as "Jinma River", is the main stream of Minjiang River and is mainly used for flood discharge. The one at the foot of the east is called Neijiang, which is an artificial water diversion channel and is mainly used for irrigation.

It is the oldest and only water conservancy project in the world, which is characterized by no dam to divert water. Scientifically solved the problems of automatic river diversion, automatic sediment discharge and control of incoming water flow.
