Tourist Attraction :
- Under the Beas Project, the dam was completed in 1977 and its primary purpose is hydroelectric power generation.
- Part of a run-of-the-river power scheme, it diverts the waters of the Beas to the southwest through a 38 km (24 mi) long system of tunnels and channels.
- The water is used for power generation at the Dehar Power House before being discharged into the Sutlej River, connecting both rivers.
- The power house has an installed capacity of 990 MW.
- Water diverted by the 76 m (249 ft) tall Pandoh Dam is first sent south through the 13.1 km (8 mi) Pandoh-Baggi Tunnel which terminates at the beginning of a 11.8 km (7 mi) long channel.
- At the end of the channel, the water is stored at the Sundar Nagar Balancing Reservoir at 31°32′05″N 76°53′11″E.
- The reservoir has a live capacity of 3,700,000 m3 (3,000 acre·ft). From the balancing reservoir, water is again sent south through the 12.38 km (8 mi) long Sundar Nagar Slapper tunnel. The tunnel ends just before the Dehar Power House at 31°24′47″N 76°52′06″E.
- It splits into three sections followed by six penstocks before reaching the power house. Water from each penstock is fed into a single 165 MW Francis turbine-generator and then discharged in the Sutlej.
- The change in elevation affords a hydraulic head of 335 m (1,099 ft).
