Design
Water supplied to the power station is first diverted from the Bhagirathi River into a 16 km (10 mi) long tunnel by the 81 m (266 ft) long Bhali (Joshiyara) Dam located upstream near Bhali at 30°43′46"N 78°25′25"E. The difference in elevation between the barrage and the power station affords a design hydraulic headHydraulic head
