Water storage in 91 major reservoirs goes down by one percent

37 Reservoirs out of these 91 have hydropower benefit with an installed capacity of more than 60 MW.

The water storage available in 91 major reservoirs of the country for the week ending on October 04, 2018 was 120.921 BCM which is 75% of the total storage capacity of these reservoirs. This percentage was at 76% for the week ending on September 27, 2018. The level of water storage in the week ending on October 04, 2018 was 113% of the storage of corresponding period of last year and 104% of storage of average of the 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 an installed capacity of more than 60 MW.  

REGION WISE STORAGE STATUS

NORTHERN REGION

The northern region includes States of Himachal Pradesh, Punjab and Rajasthan. There are six reservoirs under CWC monitoring having a total live storage capacity of 18.01 BCM. The total live storage available in these reservoirs is 16.53 BCM which is 92% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 82% and average storage of the last ten years during the corresponding period was 82% 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 the 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 a total live storage capacity of 18.83 BCM. The total live storage available in these reservoirs is 15.85 BCM which is 84% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 77% and average storage of the last ten years during the corresponding period was 76% 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 the 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 a total live storage capacity of 31.26 BCM. The total live storage available in these reservoirs is 17.47 BCM which is 56% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 72% and average storage of the last ten years during the corresponding period was 68% of the live storage capacity of these reservoirs. Thus, storage during the current year is less than the storage of last year and is also less than the average storage of the 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 a total live storage capacity of 42.30 BCM. The total live storage available in these reservoirs is 33.75 BCM which is 80% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 65% and average storage of the last ten years during the corresponding period was 74% 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 the 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 a total live storage capacity of 51.59 BCM. The total live storage available in these reservoirs is 37.32 BCM which is 72% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 55% and average storage of the last ten years during the corresponding period was 68% 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 the last ten years during the corresponding period.

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