Largest Dam Spillway 7 Gates Opening
Tarbela Dam, spanning the powerful Indus River in Pakistan, stands as one of the world’s largest earth-filled dams. Its spillway plays a vital role in flood management, structure safety, and hydropower efficiency.

Watch the Spillway in Action
Above is a dramatic video titled “Largest Dam Spillway 7 Gates Opening” showing the spillway gates in operation—an impressive engineering spectacle.
What is a Spillway?
A spillway is a controlled outlet on a dam used to safely channel excess water downstream, preventing structural stress and overtopping. At Tarbela, this is achieved through gated service spillways, built as durable concrete passages to handle immense water pressure during floods.
Spillway Design at Tarbela Dam
Type: Service spillway featuring multiple gated openings. Structure: Heavy-duty concrete chutes that regulate and direct water flow. Capacity: Built to discharge millions of cubic feet per second during peak water levels.

Importance of Tarbela’s Spillway
Function
Description
Flood Control
Safely releases excess water to protect downstream communities.
