For the week ending on May 09, 2019, the water storage available in 91 major reservoirs of India was 38.734 BCM, which is 24% of the total storage capacity of these reservoirs. This percentage was at 25 for the week ending on May 02, 2019. The level of water storage in the week ending on May 09, 2019 was 116% of the storage of the corresponding period of last year and 105% 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 STATES

The northern states include Himachal Pradesh (HP), Punjab (PB), and Rajasthan (RJ). 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 8.80 BCM which is 49% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 18% and the average storage of the last ten years during the corresponding period was 26% 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 STATES

The eastern states include Jharkhand (JH), Odisha (OR), West Bengal (WB), and Tripura (TR). 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 5.87 BCM which is 31% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 33% and the average storage of the last ten years during the corresponding period was 28% of the live storage capacity of these reservoirs. Thus, storage during the current year is less than the corresponding period of last year but is better than the average storage of the last ten years during the corresponding period.

WESTERN STATES

The western states include Gujarat (GJ) and Maharashtra (MH). 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 4.74 BCM which is 15% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 21% and the average storage of the last ten years during the corresponding period was 24% 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 STATES

The central states include Uttar Pradesh (UP), Uttarakhand (UK), Madhya Pradesh (MP), and Chhattisgarh (CG). 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 11.95 BCM which is 28% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 26% and the average storage of the last ten years during the corresponding period was 25% 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 STATES

The southern states include Andhra Pradesh (AP), Telangana (TG), 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 7.38 BCM which is 14% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 13% and the average storage of the last ten years during the corresponding period was 16% 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 the last ten years during the corresponding period.

OVERALL STATUS

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