Agreement on the ad-hoc sharing of the Teesta Waters between India and Bangladesh reached during the 25th meeting of the Indo-Bangladesh Joint Rivers Commission held in July, 1983 at Dhaka.

The Parties agree that, pending findings of the Joint Rivers Commission, 36 percent of water of the Teesta flows shall be allocated to Bangladesh, 39 percent to India and a further 25 percent shall remain unallocated. These shares will be subject to re-allocation upon the completion of scientific studies by the Joint Teesta/Tista Committee. It was also decided that Government officials from both sides shall meet urgently for purposes of implementation of the present Agreement.
