Higher Krishna water inflow bolsters Chennai reservoirs amid poor monsoon rainfall
Chennai is relying on Krishna water inflows from Andhra Pradesh to maintain reservoir levels during a weak southwest monsoon. Despite low storage in source reservoirs, the water transfer is providing a critical buffer for the city's drinking water supply.
Why it matters
It illustrates the critical nature of inter-state water resource management in mitigating urban water crises caused by climate variability.
Even as widespread rainfall continues to evade the catchments of Chennai’s reservoirs, Krishna water has emerged as a vital source, helping stabilise storage and drinking water supply. Chennai received a high volume of Krishna water on Saturday for this spell.
The State’s entry point of Kandaleru Poondi canal received nearly 464 cubic feet per second of water (cusecs), helping prevent a rapid decline in reservoir levels amid the lack of significant rainfall.
For now, Krishna water remains the only source replenishing storage during the weak southwest monsoon.
The neighbouring districts, including Tiruvallur and Kancheepuram, have a rain deficit of more than 25% this season.
