Negotiations on how to share the water have been going on since 1983. A 2011 interim deal - that was supposed to last 15 years - gave India 42.5% of the Teesta’s waters and gave Bangladesh 37.5%.
The Teesta river originates in Sikkim and flows through West Bengal as well as Bangladesh. India claims a share of 55 percent of the river’s water.
Bangladesh wants 50 percent of the Teesta’s waters between December and May every year, because that’s when the water flow to the country drops drastically.
