What is the issue?
- Protests have erupted in Karnataka due to escalating tensions over the sharing of Cauvery River water with neighboring Tamil Nadu.

About Cauvery Water Dispute
- The Cauvery River, which flows through the southern Indian states of Karnataka, Tamil Nadu, Kerala, and the Union Territory of Puducherry, has been a focal point of one of the most contentious water disputes.
- This long-standing conflict, known as the Cauvery water dispute, has its roots in historical agreements and differing demands.
- Both Karnataka and Tamil Nadu have historically staked claims to substantial portions of the river’s water, primarily to meet their agricultural and irrigation requirements.
- Regrettably, this contention has often escalated into tensions, protests, and, regrettably, even instances of violence in the affected regions.
- The Cauvery River, often referred to as the "Ganges of the South," is a vital water resource for the southern states. Its waters are used primarily for irrigation, providing sustenance to millions of farmers.
- The dispute revolves around how the river water should be distributed among these states for various uses, including irrigation, drinking water, and industrial purposes.
Background
- The Cauvery River water dispute has its origins dating back to 1892 during British colonial times, involving the Madras Presidency and the princely state of Mysore.
- In 1924, they reached an agreement that was valid for 50 years, but it ceased to be enforced in 1974. Following the expiration of this agreement, Karnataka began diverting water into its newly constructed reservoirs without the consent of Tamil Nadu. This action led to a post-independence dispute between the two Indian states over the sharing of Cauvery River water.
- In 2018, the SC declared the River Cauvery a national asset and upheld the water-sharing arrangements which had been finalized by the Cauvery Water Disputes Tribunal (CWDT).
- It ruled that Karnataka would get 284.75 TMC, Tamil Nadu 404.25 TMC, Kerala 30 TMC and Puducherry 7 TMC.
- The Union Government was directed to notify the Cauvery Management Scheme.
- The Cauvery Water Management Authority (CWMA) and the Cauvery Water Regulation Committee (CWRC) was established to implement the decision of the Court and the tribunal.

- It is often called the Dakshin Ganga (the Ganges of the South) and considered one of the sacred rivers of India
- It is a perennial river with very few fluctuations in water flow making it an important river for irrigation and hydroelectricity generation.
- Extent: The Kaveri river extends for 800 Kms from its origin to the Bay of Bengal. The majority of this lies in Tamil Nadu (416 Kms) and Karnataka (320 Kms).
- Tributaries:
