Why in the News
The Central Water Commission (CWC) has reported that water storage in major reservoirs has fallen below 40 percent, with several river basins showing declining levels across India.
Key Findings
- Total reservoirs monitored: 166
- Current live storage: ~38.7 percent of capacity
- Earlier (April 2026): ~44.7 percent
- Decline observed across multiple regions
States with Declining Reservoir Levels
- Assam, Goa, Karnataka, Kerala, Madhya Pradesh, Tamil Nadu, Tripura, and West Bengal
- Several reservoirs in these states are below 40 percent capacity
River Basins in Concern
- Ganga Basin
- Godavari Basin
- Narmada Basin
- Krishna Basin
- Kaveri Basin
- Krishna basin particularly weak (~22 percent)
Worst Affected Regions
- Northeast and Eastern India
- Assam, Tripura, West Bengal show sharp depletion
- Southern states like Tamil Nadu and Karnataka also under stress
Important Data
- Total live storage capacity: 183.565 BCM
- Current storage: 71.082 BCM
- About 20 reservoirs linked to hydropower
Key Concepts
- Live Storage: Usable water available in reservoirs
- Normal Storage: Average storage based on last 10 years
