New Delhi: This is our third report on the level of water in 91 major reservoirs of the country. The situation is worsening constantly. For the week ending on 1 June, the water level was 33.407 billion cubic metres (bcm), which is 21% of total storage capacity of these reservoirs. This percentage was at 22 for the week ending on 25 May.

First report

Second report

The total storage capacity of these 91 reservoirs is 157.799 bcm which is about 62% of the total storage capacity of 253.388 bcm which is estimated to have been created in the country. 37 reservoirs out of these 91 have hydropower benefit with an installed capacity of more than 60 MW.

Water level in northern areas

The northern region includes States of Himachal Pradesh, Punjab and Rajasthan. There are six reservoirs under Central Water Commission (CWC) monitoring having a total live storage capacity of 18.01 bcm. The total live storage available in these reservoirs is 4.53 bcm which is 25% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 22% and average storage of last 10 years during the corresponding period was 29% of the live storage capacity of these reservoirs. Thus, storage during the current year is better than the corresponding period of last year but is less than the average storage of last 10 years during the corresponding period.

East

The Eastern region includes States of Jharkhand, Odisha, West Bengal and Tripura. There are 15 reservoirs under CWC monitoring having a total live storage capacity of 18.83 bcm. The total live storage available in these reservoirs is 4.86 bcm which is 26% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 20% and average storage of last 10 years during the corresponding period was 20% of the live storage capacity of these reservoirs. Thus, storage during the current year is better than the corresponding period of last year and is also better than the average storage of last 10 years during the corresponding period.

West

The Western region includes States of Gujarat and Maharashtra. There are 27 reservoirs under CWC monitoring having a total live storage capacity of 27.07 bcm. The total live storage available in these reservoirs is 6.43 bcm which is 24% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 13% and average storage of last 10 years during the corresponding period was 23% of the live storage capacity of these reservoirs. Thus, storage during the current year is better than the storage of last year and is also better than the average storage of last 10 years during the corresponding period.

Central regions

The Central region includes States of Uttar Pradesh, Uttarakhand, and Chhattisgarh. There are 12 reservoirs under CWC monitoring having a total live storage capacity of 42.30 bcm. The water level in the reservoirs of this region was such that the total live storage became 13.70 bcm which is 32% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 22% and average storage of last 10 years during the corresponding period was 18% of the live storage capacity of these reservoirs. Thus, storage during the current year is better than the storage of last year and is also better than the average storage of last 10 years during the corresponding period.

South

The Southern region includes States of Andhra Pradesh, Telangana, AP&TG (Two combined projects in both states) Karnataka, Kerala and Tamil Nadu. There are 31 reservoirs under CWC monitoring having a total live storage capacity of 51.59 bcm. The total live storage available in these reservoirs is 3.89 bcm which is 8 % of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 10% and average storage of last 10 years during the corresponding period was 17% of the live storage capacity of these reservoirs. Thus, storage during the current year is less than the corresponding period of last year and is also less than the average storage of last 10 years during the corresponding period.

States having better storage than last year for the corresponding period are Punjab, Rajasthan, Jharkhand, Odisha, West Bengal, Tripura, Gujarat, Maharashtra, Uttar Pradesh, Madhya Pradesh, Chhattisgarh, and Telangana. States having equal storage than last year for the corresponding period are Himachal Pradesh, AP&TG (Two combined projects in both states). States having lesser storage than last year for the corresponding period are Uttarakhand, Andhra Pradesh, Karnataka, Kerala, and Tamil Nadu.

Nationally, the water level of 1 June was 128% of the storage of corresponding period of last year and 105% of storage of average of last 10 years.
