More worrying is the fact that MET department data shows sustained dry conditions in hundreds of districts since June last year.

When rainfall since June 2017 is considered - which includes 2017 monsoon months - IMD data shows disturbing trends.

The IMD's standardized precipitation index (SPI) showed mild to extremely dry conditions in 368 districts, thus indicating sustained periods of dry conditions for almost a year.

India's 63% rainfall deficit during January and February 2018 further compounds the problem.

Data reveals worrying stats about reservoirs in India

Latest government data shows that 91 major reservoirs across India are running, on an average, at 25% capacity. This figure is 16% lower than in the corresponding period last year, and 10% lower than the 10-year-average.

Worst-affectedNorth, Central, West India bear brunt of rainfall deficit

Most of the worst affected districts lie in North, Central, and West India, along with some places in the East like Jharkhand and Bihar.

In North India, the rainfall deficit is particularly pronounced in states like Punjab, Haryana, Uttar Pradesh, and Rajasthan.

In January-February 2018, the region saw a worrying 67% deficit in rainfall.

Water shortagesWater shortages have already begun to show

Punjab, Jharkhand, Odisha, Gujarat, UP, MP, Chhattisgarh and Telangana were named as states with lower water levels corresponding to the same period last year.

Additionally, the US-based World Resources Institute has named India among countries facing acute water shortages.

Shortages have already begun to show - last month, the Gujarat government stopped irrigation water supply owing to low levels in the Sardar Sarovar dam.
