INDIA FACES DECLINE IN WATER STORAGE

GS3 ENVIRONMENT 

Overview:

Water storage levels in major reservoirs across India have been declining for the twelfth consecutive week, as reported by the Central Water Commission (CWC). This decline is largely due to deficient post-monsoon and winter rainfall, raising concerns about future water availability for various sectors.

Current Water Storage:

• Total storage in 155 major reservoirs stands at 119.505 BCM, 66% of their total capacity (180.852 BCM).
• While this is higher than last year’s levels and the decade average, ongoing rainfall shortages threaten future water supply.

Deficient Rainfall:

• The India Meteorological Department (IMD) reports that 83% of India experienced deficient rainfall from January 1 to 24.
• Winter rainfall in January is 62% below normal, contributing to the water storage decline.

Regional Breakdown:

• North: 11 reservoirs at 38% capacity; Punjab’s Thein dam at 18%, Himachal Pradesh at 31%.
• East: 25 reservoirs at 63.64%; Bihar at 25%, Nagaland at 46%, others above 70%.
• West: 50 reservoirs at 78%; Goa near full at 93%, Maharashtra at 79%, Gujarat at 73%.
• Central: 26 reservoirs at 69%; Uttar Pradesh below 60%, Madhya Pradesh at 73%.
• South: 43 reservoirs at 66%; Tamil Nadu at 86%, Andhra Pradesh at 77%, Telangana at 74%.

Future Projections: IMD forecasts below-normal rainfall until February 5, which may further deplete water storage levels, intensifying the water crisis in affected regions.
