The Kundah hydro-electric project is the one of the biggest schemes executed to generate electricity in the Tamil Nadu state. The group of peaks Devarbatta, Karaikada, Koulingabetta and Porthimund, all over 2400 Metres ASL (above sea level) in Nilgiris drain their water into the two streams, the Avalanche and the Emerald. These two dams along with Upper Bhavani form the major source of water for Kundah hydro-electric project. Kundah hydro-electric project is a symbol of India-Canada friendship and co-operation.
