Explanation:

Pancheshwar Dam is a rock-fill dam which is  being constructed on the Sarda River (also known as Mahakali in Nepal), which  forms the international boundary between India and Nepal. 

Pancheshwar is the biggest dam to be planned in Uttarakhand under a commitment made by India to Nepal under the 1996 Mahakali Treaty. The long-pending project got a fillip when Prime Minister Narendra Modi visited Nepal in 2014. A Pancheshwar Development Authority was set up consequently to finalise the project. The project is to come up near the Pancheshwar temple, 2.5 km downstream of the confluence of the Mahakali and Sarju rivers. It entails two dams working in tandem. The main Pancheshwar dam would rise 311 metres and the second one downstream would be 81 metres high.
