Mekedatu Project

Subject – Geography

Context – Tamil Nadu has been opposing the Mekedatu project and unanimously passed a resolution urging the Union government not to accord permission to Karnataka to construct the reservoir.

Concept –

  • The Mekedatu multi-purpose project involves building a balancing reservoir across the Cauvery River near Kanakapura in Ramanagaram district.
  • It envisages supplying drinking water to Bengaluru and Ramanagaram districts, besides generation of power.
  • The project was conceived in 2013 and in 2017, the Karnataka state cabinet decided to implement it.
  • The project, however, ran into a controversy after Tamil Nadu opposed it on the grounds that the project violates the Cauvery Water Disputes Tribunal award.

The Cauvery River

  • The Cauvery River (Kaveri) is designated as the ‘Dakshina Ganga’ or ‘the Ganga of the South’.
  • The Cauvery River rises at an elevation of 1,341 m at Talakaveri on the Brahmagiri range near Cherangala village of Kodagu (Coorg) district of Karnataka.
  • The total length of the river from origin to an outfall is 800 km.
  • It flows in a southeasterly direction for 705 km through the states of Karnataka and Tamil Nadu and descends the Eastern Ghats in a series of great falls.
  • Left Bank: the Harangi, the Hemavati, the Shimsha, and the Arkavati.
  • Right Bank: Lakshmantirtha, the Kabbani, the Suvarnavati, the Bhavani, the Noyil, and the Amaravati joins from the right.
  • At Hogennekkal Falls, it takes a Southerly direction and enters the Mettur Reservoir.
  • A tributary called Bhavani joins Cauvery on the Right bank about 45 Kms below Mettur Reservoir. Thereafter it enters the plains of Tamil Nadu.
  • Two more tributaries Noyil and Amaravathi join on the right bankand here the river widens with a sandy bed and flows as ‘Akhanda Cauvery
  • Many projects were completed in this basin which
    • Included Krishnarajasagar in Karnataka, Mettur dam and Cauvery delta system in Tamil Nadu. LowerBhavani, Hemavati, Harangi, Kabini are important projects completed duing the plan period.
