The storage will likely be maintained at this level as remnants of cyclone Ditwah and the emergence of La Nina could lead to more showers

The storage in the major 166 Indian reservoirs continued below 90 per cent of the capacity even as the southern region experiencing 47 per cent surplus rainfall since November 27.
Data from the Central Water Commission (CWC) showed that the level in the key reservoirs was 86.41 per cent of 183.565 billion cubic metres (BCM) capacity at 158.624 BCM. Compared with a year ago and the normal storage (last 10 years) it was 7 per cent and 22 per cent higher, respectively.
Data from the India Meteorological Department (IMD) showed that barring the southern peninsula, the rest of the country received deficient rainfall last week.
Overall, there was 21 per cent deficient rainfall. However, post-monsoon rainfall from October 1 to December 3 was 23 per cent surplus. Data received from 730 districts showed that 17 per cent of them received deficient rainfall.
Among the five regions, only in the western region was the storage above 90 per cent. The 53 reservoirs in the western region were filled to 94 per cent or 35.967 BCM of the 38.094 BCM. Goa’s lone reservoir was almost full, while the storage in Maharashtra and Gujarat was 95 per cent and 94 per cent, respectively.
The level in the southern region’s 47 reservoirs was 84 per cent of the 55.287 BCM capacity at 46.408 BCM.The storage in Tamil Nadu increased to 93 per cent. In Andhra, it was 89 per cent and in Telangana, it was 87 per cent. In Kerala and Karnataka, the level was about 80 per cent.
Madhya Pradesh continued to have a storage of 90 per cent in the central region, where the 28 reservoirs were filled to 88 per cent or 42.820 BCM of the 48.588 BCM capacity. Uttarakhand’s level was nearly 90 per cent, while it was 86 per cent and 79 per cent, respectively, in Chhattisgarh and Uttar Pradesh.
The 11 reservoirs of the northern region were filled to 82 per cent of the 19.836 BCM capacity at 16.311 BCM. Rajasthan’s dams were filled to 97 per cent, while those in Punjab and Himachal had a storage of 84 per cent and 76 per cent, respectively.
In the eastern region, the level in the 27 reservoirs was 79 per cent of the
21.759 BCM capacity at 17.118 BCM. Meghalaya’s lone reservoirs continued to brim, but in Assam the level dropped below 45 per cent. The storage in Bengal improved to over 50 per cent and in Odisha, it was nearly 85 per cent. Tripura’s level was 88 per cent, while in Bihar’s lone reservoir it was 55 per cent.
The storage will likely be maintained at this level as remnants of cyclone Ditwah and the emergence of La Nina could lead to more showers.
