The major reason for the marginal decline in the total water levels in the current year is lower inflows in 14 reservoirs. While water levels fell in the 1-5% range in 10 of them the shortage exceeded 5% in about four. Large reservoirs where water levels are less than in the previous year are mainly in the northern region and include Bhakra (-5.6%), Pong (-2.6%) and Ranjith Sagar (-2.3%) in Punjab, RP Sagar (-1.4%) in Rajasthan, Ram Ganga (-1.8%) and Tehri (-1.8%) in Uttarakhand, Sardar Sarovar (-1.6%) in Gujarat and Sri Salam (-0.7%) in Andhra Pradesh. But with shortfall levels being so minimal, it is not unreasonable to expect a partial if not full restoration of water levels if adequate rains prevail near the reservoirs in the next two months. And more important, irrigation and drinking water, rather than power will be the bigger casualty from any shortfall in rains. For instance in the last drought when hydro power generation declined by more than a tenth, overall electricity generation picked up by 3% as higher power generation by thermal plants more than made up for shortfalls. There are no substitutes for irrigation and potable water sources.
