India is home to hundreds of major, medium, and small dams spread across different states and river systems. These dams and reservoirs are crucial for irrigation, hydroelectric power generation, drinking water supply, flood control, and industrial development. Due to India’s vast river network and seasonal monsoon rainfall, dams play a key role in water storage and management throughout the year.

For students preparing for SSC, Railway (RRB), Banking, Defence, UPSC, State PSC, Rajasthan Government Exams, and other competitive examinations, the List of Dams and Reservoirs in India is one of the most important General Knowledge topics. Questions are frequently asked about dams, rivers, states, and their purposes.

What Are Dams and Reservoirs?

A dam is a barrier constructed across a river to control water flow, while a reservoir is the artificial lake formed behind the dam to store water. Together, they help in water conservation, irrigation, electricity generation, and flood control.
