Karnataka’s reservoirs at 43% but summer stress builds

Bengaluru: At the halfway mark of a punishing summer, concerns over potable water are steadily rising although reservoirs across Karnataka have — so far — stayed clear of crisis levels.In a significant improvement from last year's 34% storage, major reservoirs are currently at 43% of their total capacity. While this is a relief for the govt, officials caution that the existing buffer may shrink rapidly due to the heat. Data from Karnataka State Natural Disaster Monitoring Centre shows storages in reservoirs in the Krishna basin stand at 34%, while major hydel reservoirs have 38%. The Cauvery basin reservoirs are at 48% of their storage capacity. The Cauvery basin currently holds 55.3tmcft of water — slightly lower than the 59.9tmcft recorded at this time last year — while Krishna basin reservoirs have marginally improved to 142.7tmcft. Hydel reservoirs stand at 115.4tmcft but officials say the real test is only beginning. With irrigation releases for summer crops ending, authorities are focusing on conserving water for drinking and industrial needs. Water resources department officials attribute the relatively stable situation to last year's bountiful rain and improved water management. Unlike previous years, planning has been more measured. A senior official said, "This time, the govt acted well in advance. Farmers and farmer outfits were informed about what to cultivate and whether water would be supplied for the first or second crop, ensuring there are no unrealistic expectations. Farmers in irrigated areas usually plan for two crops and, earlier, there was political pressure to promise water for two crops. We are also issuing updates and 15-day advance forecasts to deputy commissioners, who pass the information to farmers." Bangalore Water Supply and Sewerage Board is also carefully managing the situation. Chairperson Ram Prasath Manohar appealed to people saying: "People should not waste water. Misusing water just because it is available is wrong, and penalties will be imposed." Meanwhile, the rural development and panchayat raj department revealed 324 villages across 60 taluks in 20 districts have reported potable water scarcity. "To address this, the govt has already allocated Rs 60 crore to districts," said minister Priyank Kharge. "Additionally, Rs 48 crore was released to clear pending bills for works undertaken under the task force in March 2026. Besides, Rs 14.5 crore has been allocated to repair drinking water units."
