MUMBAI – Water levels in 166 key reservoirs across the country were 54.73 billion cubic metres as of Thursday, down 6.1% from 58.30 billion cubic metres in the same period last year, according to data from the Central Water Commission. This marks the first year-on-year decline in water levels since August 2024. The current water levels account for 29.8% of the total live storage capacity, and 18.6% above the average storage over the past 10 years, the data showed.

The delay in the onset of the southwest monsoon over the country is likely to be the reason for the one-year dip in reservoir levels, particularly since the monsoon set in significantly earlier last year. The onset of the monsoon over Kerala occurred on Thursday, three days after the normal date of Jun. 1. In 2025, the monsoon hit the Kerala coast on May 24, eight days ahead of its normal date.

India received 16.4 millimetres of rainfall in the week ended Wednesday, 10% below the normal of 18.2 millimetres for the period, according to the India Meteorological Department. 

The water level in reservoirs in the northern region, which includes Rajasthan, Himachal Pradesh, and Punjab, was 7.52 billion cubic metres as of Thursday, which is 37.9% of the total live capacity. In the same period last year, the water level was 29.8% of the total capacity.

The water level in reservoirs in the eastern region was 5.05 billion cubic metres, or 23.2% of the total live storage capacity, compared with 25.7% a year ago. The region comprises Assam, Jharkhand, Odisha, Tripura, Nagaland, West Bengal, and Bihar.

Reservoirs in the western region held 12.70 billion cubic metres, or 33.3% of the total live storage capacity of 53 reservoirs in the region, slightly up from 33.2% a year ago. The western region includes Maharashtra, Gujarat, and Goa.

In the central region, which includes Madhya Pradesh, Uttar Pradesh, Uttarakhand, and Chhattisgarh, the water level in reservoirs was 17.47 billion cubic metres. As of Thursday, the water level was 36.0% of the total live storage capacity, compared with 31.0% a year ago.

The water level in the southern region was 11.98 billion cubic metres, or 21.7% of the total live storage capacity of the 47 reservoirs, according to the data. The region includes Andhra Pradesh, Telangana, Karnataka, Kerala, and Tamil Nadu. At this time last year, the water level was 34.6% of the total live storage capacity.

As of Thursday, 112 of 166 reservoirs across the country had water levels at 40% or below their total live storage capacity, the data showed. Two reservoirs recorded water levels at 81–90% of total capacity, seven at 71–80%, 13 at 61–70%, 12 at 51–60%, and 20 at 41–50% of total capacity. No water reservoirs were at full capacity or had water levels between 91% and 99%.  End
