A barrage in irrigation systems is designed to control and manage water flow in rivers or streams. Here’s what it does:

Keeps Water Levels Up: It raises the water level upstream, so you have a steady supply of water for your fields, even when it’s dry.

Controls Water Flow: It helps regulate how much water flows down the river, making sure there’s enough for irrigation.

Directs Water: It channels water from the river into irrigation systems, so crops get the water they need.

Helps with Floods: It manages excess water, reducing the risk of floods.

So, a barrage is like a helpful water manager that ensures your crops get enough water and keeps things running smoothly!
