The Central Water Commission has suggested that 80 per cent of the 91 major reservoirs in the country have storage below normal. Of these, 11 have zero per cent storage, making the water crisis acute.
The official rainfall season starts from June 1 to September 30, but the overall monsoon deficiency until June 22 still remains around 39 per cent.
While monsoon progress has been staggering, 84 per cent of the meteorological subdivisions have recorded deficient rainfall, India Meteorological Department (IMD) data shows.
Of the 36 subdivisions, 25 per cent have recorded “deficient” rainfall, while six subdivisions have recorded rainfall in the category of “large deficient”.
Odisha and Lakshadweep subdivisions have recorded “normal” rainfall, whereas Jammu Kashmir and East Rajasthan recorded “excess” rainfall, the Andaman and Nicobar Islands registered rainfall under the “large excess” category.
The India Meteorological Department has four divisions – east and the north east, south peninsula, central India and northwest India with the east and northeast India division registering deficient rainfall.
While in the 10 subdivisions of central India, Odisha is the only one to receive normal rainfall.
Four subdivisions, including three from the Maharashtra – Vidarbha, Marathwada and central Maharashtra – have recorded rainfall in the category of “large deficient”. The east Madhya Pradesh subdivision has also recorded rainfall in the same category.
Vidarbha, Marathwada and central Maharashtra subdivisions have been reeling under a drought-like situation, with water levels in reservoirs reaching extremely low levels.
Although the Gujarat and Saurashtra and the Kutch subdivisions under central India have recorded “deficient” rainfall, Cyclone Vayu helped the situation.
With Chennai suffering a severe water crisis, the Tamil Nadu, Puducherry and Karaikal subdivision has a deficiency of nearly 38 per cent.
Monsoon reached Kerala on June 8, a week after its normal onset date. Its progress slowed due to Cyclone Vayu in the Arabian Sea, which furcher delayed the advancement in several parts of the country.
The situation, however, is likely to improve. The IMD on Sunday said monsoon has further advanced into east Uttar Pradesh, some parts of central Maharashtra, most parts of Marathwada and Vidarbha.
