Tamil Nadu Passes Resolution Against Karnataka’s Mekedatu Dam Project in Assembly Over Drinking Water Concerns
Tamil Nadu’s Assembly passed a resolution opposing Karnataka’s proposed Mekedatu dam, citing significant concerns regarding reduced Cauvery River flow, which threatens downstream drinking water supplies, agricultural irrigation, and local livelihoods.
On Friday, the Tamil Nadu Legislative Assembly passed a resolution expressing strong opposition to Karnataka's proposed Mekedatu dam project on the Cauvery River, and reiterating its concerns about the project's potential adverse effects on Tamil Nadu's drinking water and irrigation supplies. In addition, the resolution requests the Union Government to deny all required regulatory approvals including environmental and technical for the proposed Mekedatu project.
Lawmakers stated that if there were to be additional storage or diversion of water upstream of the Cauvery River from Tamil Nadu, this would potentially reduce the natural flow of the Cauvery River into Tamil Nadu during periods of low stream discharge. This initiative continues Tamil Nadu's long-standing position in the ongoing interstate water dispute in which both states depend on the Cauvery River basin to meet their agricultural and drinking water needs.
Why is Tamil Nadu Opposing the Mekedatu Dam Project?
Here are some of the major reasons behind Tamil Nadu Assembly opposing the Mededatu Dam Project along with impact on the larger population:
1. Upstream Storage Could Reduce Cauvery Flow Into Tamil Nadu
The Mekedatu project was opposed by Tamil Nadu government officials because it would provide the state of Karnataka with the ability to build a reservoir that would store water upstream of the border between Tamil Nadu and Karnataka. Legislators expressed concern over this increase in a reservoir upstream, because it would limit the amount of water flowing naturally into Tamil Nadu.
2. Concerns Over Drinking Water Supply in Multiple Districts
The Assembly of Tamil Nadu showed considerable concern that many of its citizens, particularly those living in large urban areas, rely on the water of the Cauvery River as their primary source of drinking water. Legislators insisted that any reduction in the flow of the river downstream would have an immediate impact on the municipal systems that, if developed by local governments, require water from the river for their daily use.
3. Irrigation Dependency and Agricultural Impact
Tamil Nadu's legislators argue not just that the river is vital as a source of drinking water but also because it is integral to farming, especially in Tamil Nadu's Cauvery Delta region. Additionally, they contend that if there were less flow of water from the upstream section of Karnataka, it would severely hinder agricultural use, particularly with regard to the growing of rice which is dependent on the river for its entire crop development cycle.
When Did the Mekedatu Dam Project Rift Begin?
The dispute around the Mekedatu dam project between Karnataka and Tamil Nadu is related to the historical conflict regarding the water-sharing of the Cauvery River. However, the current conflict regarding the Mekedatu proposal began to escalate around 2013 or 2014, when Karnataka moved forward with its proposal for development of a balancing reservoir and drinking water project at Mekedatu and started drafting project reports.
Tamil Nadu promptly opposed the Karnataka proposal and asserted that the development of any new upstream storage facility would have a detrimental effect on its entitled use of the Cauvery River water as determined by existing tribunal decisions and The Supreme Court.
How the Mekedatu Dam Project Could Affect Common People?
Individuals who live downstream are generally very concerned about decreased flow of water at critical agricultural times, which places many of the agricultural communities in parts of Tamil Nadu that rely mostly on Cauvery irrigation at risk of losing their livelihoods. In addition, there are concerns about the potential for displacing people from their homes, possible environmental changes, and impacts to both river ecosystems as well as the fishing communities who depend on them.
Because of all of these competing needs for water, the project is still considered to be very sensitive. Much of the effect on the general population will depend on how the rules for sharing water are enforced as well as how the dam, if it is approved, will be operated.
