River: Cauvery (inter-state river flowing through Karnataka, Tamil Nadu, Kerala, Puducherry)
GK and monthly revision
A dry spell along the Cauvery
A weak monsoon has triggered a severe water crisis in the Cauvery basin, intensifying the long-standing inter-state dispute between Karnataka and Tamil Nadu. Karnataka faces dual pressure of meeting its own irrigation needs while adhering to water release obligations to Tamil Nadu, where vast paddy fields lie barren. The situation highlights the fragility of the Cauvery Water Management Authority's (CWMA) regulatory framework and the recurring failure of the distress-sharing formula during deficit years. This development is critical for UPSC/State PSC exams covering inter-state river disputes, Article 262, and federal water governance.
