Zangmu Dam – The Zangmu Dam, built by China on the Yarlung Tsangpo (Brahmaputra in Tibet), has raised concerns over water flow into Arunachal Pradesh. Ecological Significance – The river supports rich biodiversity, including rare species like the Gangetic dolphin, and is vital for wetlands and forests in Arunachal Pradesh.
