Asan Barrage

The Asan Barrage is a barrage in the Uttarakhand-Himachal Pradesh border region in Doon Valley (Dehradun district), northern India, situated at the confluence of the Eastern Yamuna Canal and the Asan River and about 11 km (7 mi) from Dakpathar, and 28 km. northwest of Dehradun in Uttarakhand. The barrage is 287.5m long and has water throughout the year which is fed from the river Asan and the discharge channel of the river Yamuna. Since 2020 it has been declared as Uttarakhand's first Ramsar site. Directly behind the barrage on its eastern flank, water reenters the Eastern Yamuna Canal on the west side of the Yamuna River. At a distance of 4.5 km (3 mi) from the barrage on the canal, water reaches the 30 MW Kulhal Power Plant at 30°25′43″N 77°37′46″E. The power plant contains three 10 MW Kaplan turbine-generators and has a design hydraulic head of 18 m (59 ft). Once discharged from the power station, the water is conducted by the canal 13 km (8 mi) to the 72 MW Khara Power Station at 30°21′02″N 77°36′06″E in Uttar Pradesh. The Khara Power Station contains three 24 MW Francis turbine-generators and a has a net head of 43 m (141 ft). The dam creates the Asan Reservoir, also called Dhalipur Lake. The lake is popular for bird watching and 53 species are known to make a habitat there, of which 19 are migratory species from Eurasia.
