The water level in Krishnaraja Sagar reservoir in Mandya district in Cauvery basin dropped to 80.55 feet as against its capacity of 124.80 feet on Sunday.

However, the officials of Cauvery Neeravari Nigam said that the available water at KRS and Kabini dams in Cauvery basin will be enough to meet drinking water needs until pre-monsoon showers begin in June and reservoirs receive proper inflow by July. They can draw water for drinking upto 60 feet at KRS, they said. 

As on May 5, as per the report of Karnataka State Natural Disaster Management Centre (KSNDMC), the reservoirs in the Cauvery basin, including KRS, Kabini, Hemavathi and Harangi have just 27% of water compared to their gross capacity. They have 30.46 tmcft as against their gross capacity of 114.57 tmcft. Last year, on the same day, it had 38.87 tmcft. 

KRS dam has 11.08 tmcft (22% of its gross capacity) of water as against its gross capacity 49.45 tmcft; it had 13.56 tmcft on the same day, last year. Hemavathi dam has 9.38 tmcft (25%) as against its capacity 37.10 tmcft ; last year on the same day, it had 17.71 tmcft. Kabini has 6.97 tmcft (36%) as against its capacity 19.52 tmcft ; last year on the same day, it had 4.91 tmcft.

The water for irrigation from KRS was stopped on December 9, 2023. The officials did not release water from both KRS and Kabini for summer crops or even perennial sugarcane crops and zaid crops (dry crops-Are kushki) like Bajra, Jowar, Ragi, groundnut during summer this year as the available water was reserved for drinking purpose as per the decision of Irrigation Consultative Committee and state government. 

The state received 25% deficit South-West monsoon rainfall from June to September 2023, including 27% percent deficit rainfall in south interior Karnataka, including Cauvery basin.
