Context
The Karnataka government has announced its intention to submit a Detailed Project Report (DPR) for the contentious Mekedatu balancing reservoir project to the Central government. This project, situated on the Cauvery River near the Karnataka-Tamil Nadu border, is intended for drinking water supply and power generation, but it has historically faced strong opposition from downstream Tamil Nadu.
UPSC Perspectives
Polity
The Mekedatu project is a classic example of inter-state river water disputes, a recurring theme in Indian federalism. Under the Indian Constitution, water is primarily a State subject (), but the Union government has the power to regulate and develop inter-state rivers and river valleys (). When states disagree on the sharing of river waters, the mechanism for resolution is provided under of the Constitution, which empowers Parliament to adjudicate such disputes. This led to the enactment of the , under which various tribunals, including the , have been established. Tamil Nadu argues that the Mekedatu project violates the final award of the (which was later modified by the Supreme Court in 2018), as it would impound water and affect the natural flow into the state, thereby violating the lower riparian state's rights. The requirement of clearance from central bodies like the highlights the role of the Union government in mediating and regulating infrastructure projects on shared resources.
Geographical
From a geographical perspective, understanding the Cauvery River basin is crucial for UPSC Prelims. The Cauvery River originates at Talakaveri in the Brahmagiri range in the Western Ghats, Karnataka. It flows through Karnataka and Tamil Nadu, with its basin also extending into Kerala and Puducherry, making it a complex inter-state resource. Key tributaries include the Hemavati, Harangi, Kabini, Bhavani, Lakshmantirtha, Noyyal, and Arkavati. The proposed Mekedatu (which translates to 'Goat's Leap') balancing reservoir is planned at the confluence of the Cauvery and its tributary, the Arkavati, near the Karnataka-Tamil Nadu border. Karnataka argues that this project is necessary to store excess water during monsoon years, which would otherwise flow into the sea, and to ensure drinking water for Bengaluru and surrounding districts. A balancing reservoir acts as a buffer to manage variations in river flow, storing water during high flows and releasing it during low flows, theoretically allowing Karnataka to meet its mandated releases to Tamil Nadu while securing its own needs. However, the geographical reality is that any dam upstream alters the hydrological regime downstream, raising concerns in Tamil Nadu, particularly for its agricultural delta region which heavily relies on the Cauvery waters.
Governance
The process of getting the Mekedatu project approved illustrates the complex regulatory framework for large infrastructure projects in India. The submission of a Detailed Project Report (DPR) is just the first step. For a project on an inter-state river, the DPR must be appraised and approved by the , an apex technical organization in the field of water resources under the . The assesses the hydrological viability, structural safety, and economic feasibility of the project. Furthermore, because the project area involves forest land and is located near the Cauvery Wildlife Sanctuary, it will require stringent environmental and forest clearances from the . The project must be evaluated by the and an Expert Appraisal Committee (EAC) to assess its ecological impact. The overarching governance challenge is balancing development needs—specifically drinking water security for growing urban centers like Bengaluru—with ecological conservation and equitable sharing of natural resources among states within a federal structure.
