From UPSC perspective, the following things are important :
Prelims level : Bedti-Varada Interlinking Project
Mains level : River interlinking and associated issues
Environmental groups in Karnataka have criticised the project to link the Bedti and Varada rivers in Karnataka, calling it ‘unscientific’ and a ‘waste of public money’.
Bedti-Varada Interlinking Project
- The Bedti-Aghanashini-Varade river-linking project was also included in the country’s major rivers project devised by the then PM Vajpayee government.
- The Central Government had created a task force to prepare action plans for interlinking the riverbeds in 2002.
- The project cost and the source of investments were ascertained and suggested that the project be taken up in 2016.
- The Bedti-Varada project was envisaged in 1992 as one to supply drinking water by the then government.
- The plan aims to link the Bedti, a river flowing west into the Arabian Sea, with the Varada, a tributary of the Tungabhadra river, which flows into the Krishna, which in turn flows into the Bay of Bengal.
- A massive dam will be erected at Hirevadatti in Gadag district under the project. A second dam will be built on the Pattanahalla river at Menasagoda in Sirsi, Uttara Kannada district.
- Both dams will take water to the Varada via tunnels of length 6.3 kilometres and 2.2-km. The water will reach at a place called Kengre.
- It will then go down a 6.88 km tunnel to Hakkalumane, where it will join the Varada.
- The project thus envisages taking water from the water surplus Sirsi-Yellapura region of Uttara Kannada district to the arid Raichur, Gadag and Koppal districts.
