This Week’s Call-in Show : Tipaimukh Dam in India : Its Impact


Our call in show on the proposed Tipaimukh Dam in India and its impact raised many questions in the program . Listeners from Banglades , India and from different part of the world asked questions about the feasibility of the proposed dam, its impact on the environment and other related matters.

Our guests were Dr Ainun Nishat, Country Representative, International Union for Conservation of Nature and formerProfessor of Bangladesh Engineering University. Dhaka, Dr Ashish Mazumdar, Director, School of Water Resources Engineering, Jadavpur University, Kolkata and r Sufian Khondker, Senior Associate and Chief Water Resources Engineer, Dewberry, New York.While answering questions from our listeners, they discussed at length the proposedTipai Mukh Dam.

It may be mentioned that the proposed Tipaimukh dam is to be located 500 metres downstream from the confluence of Barak and Tuivai rivers, and lies on the south-western corner of Manipur State (24°14¢N and 93°1.3¢E approximately). It is a huge earth dam (rock-fill with central impervious core) having an altitude of about 180 M above the sea-level with a maximum reservoir level of 178m and 136m as the MDDL (minimum draw down level). The dam was originally conceived to only contain the flood water in the Cachar plains of Assam but later on, emphasis has been placed on hydroelectric power generation, having an installation capacity of 1500MW with only a firm generation of 412MW (less than 30 per cent of installed capacity).


Over the past decade and half, the issue of Tipaimukh dam has created a lot of disenchantment in regard to scientific, technical, economic and environmental feasibility of the dam especially concerning with the state of Manipur. Objections are being raised in the downstream country Bangladesh too about this Tipai Mukh Dam with the fear that the dam may reduce the flow of water in Bangladesh causing severe ecological and humanitarian problem.
