Koyna Dam, often called the “Lifeline of Maharashtra”, is one of the largest dams in India and a key source of hydroelectric power generation. Built on the Koyna River, a tributary of the Krishna River, this dam is located in the Western Ghats of Satara district. Surrounded by lush greenery, hills, and wildlife, Koyna Dam is not only an engineering marvel but also a popular tourist destination in Maharashtra.
In this article, let’s explore the history, construction, importance, tourism aspects, and nearby attractions of Koyna Dam.
History of Koyna Dam
The foundation of Koyna Dam was laid in 1954, and it was completed in 1964. It was built primarily to generate hydroelectric power and provide irrigation facilities for the state of Maharashtra. The dam is a major part of the Koyna Hydroelectric Project, which is among the largest power-generating dams in India.
Interestingly, the area surrounding the dam experienced the 1967 Koynanagar earthquake, which led to further studies in dam safety and seismology. Despite this, the dam stood strong and continues to function efficiently, making it one of the most resilient dams in India.
