Cauvery water sharing dispute

Notes

• The Cauvery Water Regulation Committee (CWRC) and Cauvery Water Management Authority (CWMA) serve as the implementation mechanism for the 2007 Cauvery Water Disputes Tribunal final award, as modified by the 2018 Supreme Court judgment.
• CWRC chairperson Vineet Gupta has requested Karnataka and Tamil Nadu to develop a mutually agreed-upon distress-sharing formula.
• The CWRC order mandates Karnataka to release 3,500 cusecs of water daily to Tamil Nadu for a 15-day period.
• The release calculation is based on rainfall patterns, net inflow into four Karnataka reservoirs, long-term averages (30-year data), and Meteorological Department inputs.
• Biligundlu serves as the gauge and discharge (G&D) site for measuring river flow at the Karnataka-Tamil Nadu boundary.
• Karnataka must release 6,000-6,500 cusecs from its reservoirs to ensure 3,500 cusecs reach Biligundlu, due to the current 'very dry' state of the intermediate catchment area.
• Data indicates a 60% deficit in net inflow for Karnataka's reservoirs compared to long-term averages.
• Karnataka has initiated an appeal process before the CWMA against the CWRC's recent release order.
