Cauvery Water Dispute Escalates Over Mekedatu Dam Plans
The Cauvery River is a big river that flows through two Indian states, Tamil Nadu and Karnataka.
Tamil Nadu uses a lot of its water to grow crops, while Karnataka wants the water for drinking and local farms.
Karnataka wants to build a big dam called Mekedatu to give water to the city of Bengaluru.
Tamil Nadu says this dam would break court rules that say the river should flow freely to the south.
Because of these disagreements, the river has been a source of tension, especially when there is not enough rain.
Both sides have asked the government to step in and decide who gets how much water.
The dispute could get worse and hurt people’s jobs and homes if it is not solved peacefully.
The Cauvery river water dispute between Tamil Nadu and Karnataka remains unresolved, with recurring disagreements over water sharing.
Tamil Nadu relies on the river for agriculture across millions of acres, while Karnataka cites drinking water and local farming needs.
Karnataka plans to build the Mekedatu reservoir to supply Bengaluru’s drinking water and power, which Tamil Nadu says violates Supreme Court verdicts and the Cauvery Tribunal award.
The dispute has intensified during monsoon deficit years, prompting the Cauvery Water Management Authority to direct Karnataka to release water quotas to Tamil Nadu.
The conflict has heightened political tensions, with parties warning that it could spiral out of control and affect livelihoods.
