About Mekedatu dam project
- Being set up by the Karnataka government, the project is near Mekedatu, in Ramanagaram district, across the river Cauvery from Tamil Nadu.
- Its proposed capacity is 48 TMC (thousand million cubic feet).
- Its primary objective is to supply drinking water to Bengaluru and recharge the groundwater table in the region.
- The dispute between Karnataka and Tamil Nadu over the sharing of Cauvery waters is decades old.
- For many years, both the states have been maintaining differences over the sharing of water.
- Karnataka intends to build Mekedatu reservoir across river Cauvery near Mekedatu in Kanakapura taluk.
- However, Tamil Nadu objected saying Karnataka had not sought prior permission for the project. Its argument was that the project would affect the flow of Cauvery water to Tamil Nadu.
- In November 2014, the Karnataka government invited expressions of interest in the Rs 6,000-crore project. In its 2015 Budget, it allocated Rs 25 crore for a detailed project report.
- Tamil Nadu saw massive protests in 2015, including a state-wide bandh backed by political parties, farmers, transport unions, retailers and traders.
- The T.N. Assembly also adopted a unanimous resolution urging the Centre to stop Karnataka from building the project.
- Ahead of the 2016 Assembly polls in Tamil Nadu, delegation of Opposition leaders met the Prime Minister against Karnataka’s decision to allocate Rs 25 crore for a feasibility study.
- From Karnataka, then Chief Minister Siddaramaiah led an all-party delegation to the Prime Minister seeking the Centre’s cooperation in going ahead.
- The study has been cleared by the Central Water Commission (CWC), which has also asked for a detailed project report.
- The process cleared by the CWC needs further clearance from the Cauvery Water Management Authority (CWMA) too.
- The CWC clearance is for a report subject to certain conditions, which include the concerns raised by the Tamil Nadu government.
- The detailed report has to consider the views of the co-basin states as well.
Why Tamil Nadu is opposing the project?
- Its main argument is that the project violates the final award of the Cauvery River Water Tribunal, and that the construction of the two reservoirs would result in impounding of the flows in the intermediate catchment below the Krishnaraja Sagar and Kabini reservoirs, and Billigundulu in the common border of Karnataka and Tamil Nadu.
Arguments given by Karnataka government
- According to Karnataka, project will not come in the way of releasing the stipulated quantum of water to Tamil Nadu, nor will it be used for irrigation purposes.
