The storage level in India’s 161 major reservoirs increased this week with the revival of the south-west monsoon. Last week, the storage dropped after rising for weeks in a row.

Data from the Central Water Commission (CWC) showed that the storage was 31.81 per cent of the 182.444 billion cubic metres (BCM) capacity at 58.030 BCM. Last week, the level dropped to 30.43 per cent of the capacity.

The CWC’s weekly bulletin on the storage status in the major reservoirs showed that the current storage is higher than last year and normal (last 10 years). The rise in the level comes after the south-west monsoon revived this week after a 10-day hiatus. 

Monsoon deficiency shrinks

The rise in the storage is because the levels in the southern and western regions increased, whereas it declined in the other three regions. However, with the monsoon lashing over central and eastern parts, the situation will likely improve next week. Currently, the monsoon deficiency this month has shrunk to 5 per cent from 31 per cent at the beginning of the week. 

In the 11 reservoirs of the northern region, the level dropped to 27.31 per cent of the 19.836 BCM capacity at 5.418 BCM. The storage in Himachal Pradesh improved to 15.66 per cent and in Rajasthan to 51.78 per cent. It declined in Punjab to 36.95 per cent.

In the eastern zone, the 27 reservoirs were filled to 23.59 per cent or 5.126 BCM of the 21.724 capacity. In Assam, Tripura and Mizoram, the level in the dams was over 60 per cent of the capacity, while it was nearly 58 per cent in Meghalaya. In West Bengal, the level was 30 per cent and in Odisha, 16 per cent. 

The storage in the 50 reservoirs of the western region improved to 32.48 per cent of the 37.357 BCM capacity at 12.132 BCM. Goa’s lone reservoir was filled to over 70 per cent. The level in the dams in Maharashtra and  Gujarat was 33 per cent and 31 per cent, respectively. 

Good for kharif crops

In the central region, the 28 reservoirs were filled to 13.833 BCM or 28.57 per cent of the 48.588 BCM capacity. Barring Madhya Pradesh, where the level was 30 per cent, the dams in Chhattisgarh, Uttar Pradesh and Uttarakhand (11 per cent storage) were filled below 25 per cent.

The 45 reservoirs in the southern region witnessed copious inflow this week, raising the level to 39.08 per cent of the 54.939 BCM at 21.471. The storage in Tamil Nadu continued to be the highest in the country at 80 per cent of the capacity, while it was nearly 47 per cent in Kerala. The storage in Karnataka was nearly 40 per cent, while it was 26 per cent and 32 per cent, respectively in Andhra and Telangana. 

The higher reservoir level augurs well for the current kharif sowing season. Currently, planting of kharif crops is progressing well with the overall area up by 1.5 lakh hectares until last week.
