If we take the case of Ganges, West Bengal and Bangladesh are the highest beneficiaries of the river as it spreads the world's largest delta in these regions. If we go by your argument about yield, then Uttaranchal and Uttar Pradesh have more yields than West Bengal. So will you argue that Bengal should do less agriculture than the other states in gangetic plains. Of course, these types of problems never arise in case of Ganges as it is a perennial river. I put forth this argument to support my view that yield is least considered in sharing water.
