The Asan Barrage, also known as Dhalipur Lake, is a serene man-made reservoir situated at the confluence of the Asan River and the Eastern Yamuna Canal in the Doon Valley of Uttarakhand, India. Located approximately 43 km from Dehradun, near the village of Dhalipur, it was constructed in 1967 by the Uttar Pradesh Irrigation Department to regulate water flow for irrigation and hydroelectric power generation .
In 2020, the Asan Barrage was designated as Uttarakhand's first Ramsar site, recognizing its importance as a wetland of international significance . The reservoir spans approximately 4 square kilometers and serves as a crucial habitat for over 250 bird species, including 19 migratory species from Central Asia and Europe . Notably, it provides refuge to several endangered species listed in the IUCN Red Data Book, such as the white-rumped vulture, red-headed vulture, and Baer's pochard .
The Asan Barrage, constructed in 1967 by the Uttar Pradesh Irrigation Department, was originally built to regulate the water flow between the Asan River and the Eastern Yamuna Canal. Over the decades, this barrage transformed into a vital ecological site due to the accumulation of water and wetland habitat it fostered. In 2020, it was declared Uttarakhand’s first Ramsar Site, officially recognizing it as a wetland of international importance under the Ramsar Convention. This recognition was primarily for its crucial role in hosting endangered and migratory birds from Europe, Central Asia, and beyond.
