It is a river flow diversion project of the west flowing Yettinahole, a vital tributary of the Netravathi, through eight diversion weirs and a canal network spanning 1,000 kilometres.
The water will be pumped from the weirs to a network of five delivery chambers and then channeled eastward through giant pipes that cut across the Western Ghats. In addition, seven storage reservoirs will be constructed in several districts of Karnataka.
. The project proposes to divert nearly 24 TMC (or 672 billion litres) of water from the head-waters of the Netravathi river towards the water-scarce districts of Kolar, Ramanagara, parts of Hassan, Tumkur, Chikkaballapur, Bengaluru Rural and Devanahalli Industrial Area, – besides augmenting water to T.G. Halli and Hesaraghatta reservoirs near Bengaluru city.
It is also called as Netravati River Diversion Project.
The Yettinahole project envisages the construction of eight dams and its impact on the flora and fauna may be to be negative.
The construction may affect the elephant corridor in the region.
