Which of the following hydro-electric and irrigation multi-purpose projects is constructed across the Cauvery River at the border of Karnataka and Tamil Nadu, impounding water into the Stanley Reservoir?

💡 Solution & Explanation

The Mettur Dam is one of the largest dams in India, built across the Cauvery River in Salem district (now Krishnagiri-Salem border region) of Tamil Nadu. Completed in 1934, it creates the Stanley Reservoir, providing vital irrigation water for the Cauvery delta deltaic districts and generating hydroelectric power. The Bhavanisagar Dam is built across the Bhavani River in Erode district. Tungabhadra and Bhadra dams are located upstream in Karnataka. Mettur plays a central role in agricultural water management in southern peninsular India.
