The water storage level available in 91 major reservoirs of the country for the week ending on November 01, 2018 was 109.247 BCM which is 67% of the total storage capacity of these reservoirs. This percentage was at 70% for the week ending on October 25, 2018. The level of water storage in the week ending on November 01, 2018 was 99% of the storage of corresponding period of last year and 97% of storage of average of the last ten years.

According to a report by the Ministry of Water Resources, River Development and Ganga Rejuvenation in PIB, the total storage capacity of those ninety-one 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 the 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 15.67 BCM which is 87% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 74% 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.

EASTERN REGION

The Eastern region includes States of Jharkhand, Odisha, West Bengal and Tripura. There are 15 reservoirs under CWC monitoring having the total live storage capacity of 18.83 BCM. The total live storage available in these reservoirs is 13.50 BCM which is 72% of the total live storage capacity of these reservoirs. The storage throughout the corresponding period of last year was seventy-nine and average storage of the last 10 years during the corresponding period was seventy-fifth of the live storage capacity of those 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 the last ten years during the corresponding period.

WESTERN REGION

The Western region includes States of Gujarat and Maharashtra. There are twenty-seven reservoirs under CWC observation having total live storage capability of 31.26 BCM. The total live storage available in these reservoirs is 16.65 BCM which is 53% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 71% and average storage of the last ten years during the corresponding period was 66% 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 twelve reservoirs under CWC observation having a total live storage capability of forty-two.30 BCM. The total live storage available in these reservoirs is 30.92 BCM which is 73% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 62% and average storage of the last ten years during the corresponding period was 71% 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 thirty-one reservoirs under CWC observation having a total live storage capability of 51.59 BCM. The total live storage available in these reservoirs is 32.50 BCM which is 63% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 66% and average storage of the last ten years during the corresponding period was 66% 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 the last ten years during the corresponding period.

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