The Union water resources ministry said the reservoirs, including the Nagarjuna Sagar, Indira Sagar and Bhakra dams, contained 35.053 billion cubic metres (BCM) of water in the week ending May 25.
The water level, however, was 127 per cent of the storage reported during the corresponding period last year and 104 per cent of the decadal average, the ministry said in a statement.
Last week, the stock was 23 per cent (or 35.622 BCM) of the total storage capacity of the dams. The water level in the reservoirs has fallen to 22 per cent this week.
Punjab, Rajasthan, Jharkhand, Odisha, West Bengal, Tripura, Gujarat, Maharashtra, Uttar Pradesh, Madhya Pradesh, Chhattisgarh and Telangana have reported better storage levels.
