Welcome to India Clue Challenge #3!
India’s major infrastructure projects often combine engineering, geography, politics, and environmental concerns. Today’s challenge is about a proposed river project that has remained in the spotlight for years due to its strategic location and interstate significance.
Read each clue carefully. Every clue brings you one step closer to the answer—but don’t scroll to the end too quickly!
Clue 1
I am planned on the Cauvery River, one of South India’s most important interstate rivers.
Clue 2
My proposed location is close to the Karnataka–Tamil Nadu border, making me significant for both states.
Clue 3
I lie near a spectacular deep gorge where the Arkavathi River joins the Cauvery River, creating a famous natural landscape.
Clue 4
Although I am located in Karnataka, discussions about me frequently involve Tamil Nadu, as both states share the waters of the Cauvery basin.
Clue 5
Supporters say my primary objective is to provide drinking water to Bengaluru, one of India’s fastest-growing metropolitan cities, rather than expand irrigation.
Clue 6
If built, I could also generate approximately 400 MW of hydroelectric power while storing water in a balancing reservoir.
Clue 7
Once built, the this dam will submerge more than 5,000 hectares of protected area in the Cauvery Wildlife Sanctuary.
Final Hint
I am a proposed balancing reservoir on the Cauvery River, located near the Karnataka–Tamil Nadu border, close to the confluence of the Cauvery and Arkavathi rivers. My stated goals are to strengthen Bengaluru’s drinking water supply, improve water management during low-rainfall years, and generate hydroelectric power.
