The waters of the Kushiyara pick up tributaries from Manipur, Mizoram, and Assam . The Kushiyara rejoins with the Surma at Markuli in Ajmiriganj (Bangladesh) and flows south up to Bhairab Bazar (Bangladesh) receiving the name Kalni.

Important Points India and Bangladesh have 54 transboundary rivers between them, all of which are part of the drainage system of the Ganga-Brahmaputra-Meghna basin. After the independence of Bangladesh in 1971, the Joint River Commission was formed between India and Bangladesh in 1972. In a joint declaration issued on 16 May 1974, the PM of Bangladesh and India acknowledged the need for the flow augmentation of the Ganga in the lean season to meet the requirements of both countries. The Bangladesh government has been insistent on sealing the Teesta Waters Agreement, which has eluded settlement so far. The point of contention between India and Bangladesh is mainly the lean season flow in the Teesta draining into Bangladesh. India and Bangladesh have resolved border problems through the Land Boundary Agreement of 2015. However, both nations have locked horns over the sharing of multiple rivers that define the borders and impact lives and livelihoods on both sides.
