 "Water level in reservoirs less than last year: Central Water Commission")
The Central Water Commission on Thursday said the overall storage position of 123 major reservoirs in the country in the past week is less than that of the same period in 2019 but better than the average storage of the last ten years.
The CWC monitors the live storage status of 123 reservoirs of the country on a weekly basis. Out of these reservoirs, 43 reservoirs have hydropower benefit with installed capacity of more than 60 MW.
As per reservoir storage bulletin of October 1, live storage available in these 123 reservoirs is 148.247 BCM, which is 87 per cent of total live storage capacity of these reservoirs.
"However, last year the live storage available in these reservoirs for the corresponding period was 151.071 BCM and the average of last 10 years live storage was 129.953 BCM.
"Thus, the live storage available in 123 reservoirs as per October 1 bulletin is 98 per cent of the live storage of corresponding period of last year and 114 per cent of storage of average of last ten years," the CWC said.
The numbers of reservoirs having storage more than last year are 47 and reservoirs having storage more than average of last ten years are 103, the CWC said.
