Even as resistance grows to large dams worldwide, at least six big multipurpose projects are being planned in the upper reaches of Arunachal Pradesh. In fact, a forerunner to these dams in Lohit district of the state was conceived exactly 30 years ago - much before Narmada Sagar became a big issue in the country. The original proposal was to construct a single 257-metre-high rock-fill dam near Gerukamukh on the Assam-Arunachal border. The amended proposal is to construct at least six dams. It is, of course, a misnomer to say that the Subansiri-Dihang dam is one huge project. Actually, there would be six multipurpose dams, on the rivers Dihang and Subansiri, put together in the upper reaches of Arunachal Pradesh (see table)
