Water storage level of 91 major reservoirs declines to 33.563 bcm as on 23 May

Water storage declines to 21% of total storage capacity from 22% a week ago

The water storage available in 91 major reservoirs of the country for the week ending on 23 May 2019 was 33.563 billion cubic meters (bcm), which is 21% of total storage capacity of these reservoirs. This percentage was at 22 for the week ending on 16 May 2019. The level of water storage in the week ending on 23 May 2019 was 114% of the storage of corresponding period of last year and 104% of storage of average of last ten years.

The total storage capacity of these 91 reservoirs is 161.993 bcm which is about 63% of the total storage capacity of 257.812 bcm which is estimated to have been created in the country. 37 Reservoirs out of these 91 have hydropower benefit with installed capacity of more than 60 MW.

Northern Region

The northern region includes States of Himachal Pradesh, Punjab and Rajasthan. There are six reservoirs under CWC monitoring having total live storage capacity of 18.01 bcm. The total live storage available in these reservoirs is 7.93 bcm which is 44% of total live storage capacity of these reservoirs. The storage during corresponding period of last year was 15% and average storage of last ten years during corresponding period was 26% of live storage capacity of these reservoirs. Thus, storage during current year is better than the corresponding period of last year and is also better than the average storage of last ten years during the corresponding period.

Eastern Region

The Eastern region includes States of Jharkhand, Odisha, West Bengal and Tripura. There are 15 reservoirs under CWC monitoring having total live storage capacity of 18.83 bcm. The total live storage available in these reservoirs is 4.56 bcm which is 24% of total live storage capacity of these reservoirs. The storage during corresponding period of last year was 28% and average storage of last ten years during corresponding period was 22% of live storage capacity of these reservoirs. Thus, storage during current year is less than the corresponding period of last year but is better than the average storage of last ten years during the corresponding period.

Western Region

The Western region includes States of Gujarat and Maharashtra. There are 27 reservoirs under CWC monitoring having total live storage capacity of 31.26 bcm. The total live storage available in these reservoirs is 3.75 bcm which is 12% of total live storage capacity of these reservoirs. The storage during corresponding period of last year was 16% and average storage of last ten years during corresponding period was 21% of live storage capacity of these reservoirs. Thus, storage during current year is less than the storage of last year and is also less than the average storage of last ten years during the corresponding period.

Central Region

The Central region includes States of Uttar Pradesh, Uttarakhand, Madhya Pradesh and Chhattisgarh. There are 12 reservoirs under CWC monitoring having total live storage capacity of 42.30 bcm. The total live storage available in these reservoirs is 10.96 bcm which is 26% of total live storage capacity of these reservoirs. The storage during corresponding period of last year was 24% and average storage of last ten years during corresponding period was 22% of live storage capacity of these reservoirs. Thus, storage during current year is better than the storage of last year and is also better than the average storage of last ten years during the corresponding period.

Southern Region

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 total live storage capacity of 51.59 bcm. The total live storage available in these reservoirs is 6.38 bcm which is 12% of total live storage capacity of these reservoirs. The storage during corresponding period of last year was 12% and average storage of last ten years during corresponding period was 15% of live storage capacity of these reservoirs. Thus, storage during current year is equal to the corresponding period of last year but is less than the average storage of last ten years during the corresponding period.

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