Answer: Sikkim
Notes: A landslide recently damaged six houses and an NHPC building at the Teesta-V hydropower station in Sikkim's Gangtok district. Teesta-V is a 510 MW run-of-river hydropower project on the Teesta River, with a concrete gravity dam. The project began in 1999 and became operational in 2008, developed by NHPC. The Teesta River flows through Sikkim, West Bengal, and Bangladesh, and is a tributary of the Brahmaputra River. It forms a boundary between Sikkim and West Bengal, and its course includes a deep gorge through the Siwalik Hills.
