Mekedatu Dam Project

Mekedatu, meaning goat’s leap, is a deep gorge situated at the confluence of the rivers Cauvery and its tributary Arkavathi.

On July 6, Karnataka Chief Minister B.S. Yediyurappa said in Bengaluru that his government would go ahead with the long-pending Mekedatu dam project in the Cauvery Basin to cater to the drinking water needs of the Bengaluru Metropolitan City and surrounding areas.

Mekedatu Dam Project:

•It is a multi-purpose balancing reservoir project over Mekedatu, built at a cost of Rs 5,912, was aimed at solving the drinking water problems of Bengaluru and Ramnagar district. This project was also touted as one that could generate hydroelectricity to meet the power demand in the state.
•The Centre has given its assurance that Karnataka will not be allowed to carry out any construction on the Mekedatu dam project on the Cauvery river until its Detailed Project Report (DPR) is approved by the Cauvery Water Management Authority (CWMA).

Tamil Nadu also argues that the project is against the final order of the Cauvery Water Disputes Tribunal (CWDT) in which the SC held that no state can claim exclusive ownership or assert rights to deprive other states of the waters of inter-state rivers and  that no constructions should be made at Mekedatu without the approval of lower riparian states as per the Supreme Court order.

Cauvery Water Disputes Tribunal

and Mekedatu Dam Project:

  • The Cauvery Water Disputes Tribunal, in its final order made allocations to all the riparian States — Karnataka, Kerala and Tamil Nadu, apart from the Union Territory of Puducherry.
  • It defined a “normal year” as one in which the total yield of the Cauvery basin is 740 TMC. In a normal year, Karnataka has to release to Tamil Nadu at Biligundulu 192 TMC (as against 205 TMC in the interim award) in monthly deliveries. This comprises 182 TMC from the allocated share of TN, including 10 TMC for environmental purposes.
  • In a so-called distress year, the allocated shares are to be proportionately reduced among Kerala, Karnataka, TN and Puducherry.The Tribunal also recommended setting up the Cauvery Management Board (CMB) to implement the Tribunal’s decisions
  • As instructed by the Supreme Court, the Cauvery Water Management Authority (CWMA) was created by the Centre on 1 June 2018. The Cauvery Water Regulation Committee was created three weeks later.

Cauvery River:

  • The river Cauvery is the largest in southern India, and begins near Mercara in the Coorg region at an elevation of 1,341 m (4400 ft) above sea level towards the Western Ghats, taking an easterly course through the states of Karnataka and Tamil Nadu, before joining the Bay of Bengal.
  • The Cauvery’s upper hilly catchment lies in Karnataka and Kerala. It is influenced by the usually dependable south-west monsoon during June to September. Its lower part lies in the plains of Tamil Nadu, served by the not-so-dependable north-east Monsoon during October to December.
  • In technical water law language, Karnataka is the upper riparian state where the river originates; Tamil Nadu is a lower riparian state. Puducherry wants its share of the Cauvery because it is where the river flows into the Bay of Bengal. And Kerala actually contributes more water to the river than it can utilize, because of its geography.
  • Some of its tributaries are Arkavathi, Hemavathi, Lakshmana Theertha, Shimsa, Kabini and Harangi.
