Asan Barrage Birds Sanctuary

The Asan Barrage also known as the Dhalipur lake is located in the District of Dehradun valley on the Dehradun-Ponta road at a distance of about 35 Km. It's a small wetland of Approx. 4 SQ. K.M. Area. And has been recently declared as a Bird Sanctuary.

In 1967 a barrage was constructed near the confluence of two perennial rivers Asan and Yamuna, as a result of which a lake got created. This reservoir exists throughout the year as it is fed from the river Asan and the discharge channel of Yamuna through Dhalipur powerhouse. Although the water level is controlled, it often goes down, and swampy islands in the middle become visible, attracting a variety of marsh-loving birds like Egrets, Herons and Lapwings, etc.

This small man made reservoir attracts 53 species of water birds both divers and waders.

During winter months these 11 migratory species, namely Brahminy Duck, Pintail, Red Crested Pochard, Gadwall, Common Pochard, Mallard, Coot, Wigeon, Common Teal, Tufted Duck, Shoveller have the 90% composition in total water birds.
