It further sought an order to the CWMA to monitor the flows in the reservoirs of Karnataka every 10 days and ensure stipulated monthly/daily releases at Billigundulu.
The Tamil Nadu government said Karnataka had continued to defy the orders of the Cauvery Tribunal for allocation of water to its neighbour except a few times when there were inevitable surpluses in the reservoirs on account of floods.
The State said they had reviewed the hydrometeorological condition in the Cauvery basin on July 30 and endorsed the July 28 recommendations of the Cauvery Water Regulations Committee (CWRC) to release waters from Krishna Raja Sagara (KRS) and Kabini reservoir at the rate of 3,500 cusecs from July 29 for 15 days.
Why Tamil Nadu and Karnataka are sparring over Cauvery water? | Explained “Even if Karnataka ensured flows of 3500 cusecs for 15 days, it would get only 4.536 TMC leaving a backlog of 5.379 TMC even as per the pro rata assessment of distress as on July 28...

If the inflows into the 4 major reservoirs of Karnataka against 30 years average up to August 3, 2026 is considered, the pro-rata ratio works out to 46.34%.
Based on this pro-rata ratio, the flows due from June 1, 2026 to August 12, 2026 works out to 26.95 TMC.
The direction given by the CWRC and CWMA is only 4.536 TMC, which is far less than the quantum of water as per distress proportion,” the Tamil Nadu application has said.
The State argued that despite the CWRC/CWMA interventions, total flows realised at Billigundulu from July 29 to August 2 were only in the range of 158 cusecs to 530 cusecs.
“Thus, it is evident that Karnataka has willfully not complied with the directions of CWRC/CWMA.
It is stated that as on August 3, Karnataka is having 23.078 TMC in KRS, 18.610 TMC in Kabini, 7.827 TMC in Harangi and 28.022 TMC in Hemavathy, totally 77.537 TMC of gross storage...
This increase in the live storage is on account of recent heavy rainfall in the catchments upstream of Kabini and KRS.
Thus, Karnataka in spite of having adequate storage has failed to comply with the directions of CWMA,” Tamil Nadu has contended.
