The Rana Pratap Sagar Dam is built on the river Chambal. The Chambal River is a major river in central India, flowing primarily through the states of Madhya Pradesh, Rajasthan, and Uttar Pradesh. The dam is named after Rana Pratap, who was a prominent ruler in the region and is known for his bravery. It is a multipurpose project built for various purposes like irrigation, hydroelectricity generation, and water supply. The dam is located near the town of Rawatbhata in the state of Rajasthan. It has a large reservoir behind it, which helps in storing water during monsoons and releasing it in a controlled manner for various uses throughout the year.
