New Delhi: With the southwest monsoon in full swing in parts of the country, the water level in reservoirs has continued to improve. As a result, majority of reservoirs have recorded higher storage on a year-on-year basis.
According to data from the Central Water Commission (CWC), total live storage available in reservoirs across the country was 126.631 billion cubic metres (BCM) as of Thursday, which is about 76% of the total live storage capacity. The water level is higher than that of last year, but also better than the average storage of last ten years.
After a sluggish start which led to a rainfall deficit of nearly 33% in June, the monsoon current gained momentum mid-July and has been active since then.
So far in the four-month season, that started in June, rains in the country have been nearly normal, with most of the heavy rainfall activity concentrated in Central India due to low pressure systems that moved westwards towards Madhya Pradesh, Gujarat and east Rajasthan. Rains were also in excess along the western coast, especially in Madhya Maharashtra where rainfall has been 54% above normal.
Of the total 107 reservoirs monitored by CWC, higher year-on-year storage has been recorded in reservoirs in Himachal Pradesh, Punjab, Rajasthan, Gujarat, Maharashtra, Uttarakhand, Madhya Pradesh, Andhra Pradesh and Karnataka. Water level in reservoirs in Jharkhand, Odisha, Tripura, West Bengal, Nagaland, Uttar Pradesh, Chhattisgarh, Telangana, Kerala and Tamil Nadu has declined.
The situation is yet to improve for the 17 reservoirs in the eastern region comprising Jharkhand, Odisha, West Bengal, Tripura and Nagaland where water level is lower year-on-year. Both Jharkhand and West Bengal are among the seven sub-divisions of the country which have witnessed deficient rains this monsoon season. Parts of Jharkhand are also reeling under drought-like conditions.
According to the India Meteorological Department (IMD), another low pressure system is building over northwest Bay of Bengal and is expected to bring heavy rains over Odisha, Chhattisgarh, Madhya Pradesh, East Rajasthan, Gujarat region, and Vidarbha over the next week.
