The Karnataka government has lowered its Cauvery water release to Tamil Nadu by 57% after a dip in rainfall, according to Mid-Day.
The state of Karnataka announced a 57 percent reduction in the volume of water released from the Cauvery River to Tamil Nadu. The decision comes in response to a noticeable decline in monsoon rainfall across Karnataka, which has lowered reservoir levels.
The cut affects the scheduled release under the inter‑state water‑sharing agreement overseen by the Cauvery Water Management Authority. Earlier this month, Karnataka had been discharging the full quota agreed for the period, but the recent rainfall shortfall prompted officials to revise the figure.
Tamil Nadu's water department has been informed of the change and is expected to adjust its irrigation and drinking‑water plans accordingly. Both states have historically faced tensions over Cauvery allocations, and the latest reduction underscores the impact of weather variability on water resources.
Karnataka's water minister said the move is necessary to safeguard the state's own water security while complying with the legal framework governing the river. The situation will be reviewed regularly as the monsoon progresses.
