Overview: Uttarakhand’s First Ramsar Site
Tucked away in the serene Doon Valley of the Dehradun district, Asan Barrage Bird Sanctuary—officially known as the Asan Conservation Reserve—is not just a destination; it is a journey into the heart of Himalayan wetland biodiversity.
Often referred to as a “birdwatcher’s paradise”, this stunning blue-green water body sits at the confluence of the Asan and Yamuna rivers, near the town of Dakpathar, approximately 43 kilometres from Dehradun. The sanctuary is a man-made wetland, created as a result of the construction of the Asan Barrage in 1967 on the Asan River.
What makes Asan Barrage truly special is its extraordinary avian diversity. The sanctuary is home to over 330 species of birds, including several critically endangered species such as the red-headed vulture, white-rumped vulture, and Baer’s pochard. During winter, the wetland hosts more than 5,000 waterfowl, with high species diversity.
The sanctuary holds the distinction of being India’s first conservation reserve, established in 2005 by the Government of Uttarakhand. In October 2020, it was designated as Uttarakhand’s first Ramsar Site, recognising it as a Wetland of International Importance.
The journey to Asan Barrage, which begins from the capital city of Dehradun, is an accessible yet rewarding adventure through scenic valleys and along the banks of the Yamuna. It offers a profound sense of peace, a deep connection with nature, and an unforgettable birdwatching experience.

History of Asan Barrage Bird Sanctuary
The Construction of Asan Barrage (1967)
The story of Asan Barrage begins in 1967 when the Uttar Pradesh Irrigation Department constructed a barrage across the Asan River to regulate water flow from the Asan River into the Yamuna Canal system for irrigation and power generation purposes. The damming of the river led to siltation above the dam wall, which over time helped create some of the site’s bird-friendly habitats.
From Barrage to Bird Sanctuary
Initially constructed for power generation, the barrage gradually transformed into a wetland as sediments from the Yamuna and Asan rivers were deposited. The resulting shallow wetland areas and surrounding vegetation created ideal habitat for waterfowl, particularly during the winter migration season.
Recognition and Conservation Status
The sanctuary’s ecological significance was formally recognised over the years:
- 2002: Declared an Important Bird Area (IBA) by the Bombay Natural History Society (BNHS) and BirdLife International
- 2005: Notified as a Conservation Reserve by the Government of Uttarakhand under Section 36A of the Wildlife (Protection) Act, 1972, through notification dated August 5, 2005. It was one of India’s first conservation reserves.
- 21 July 2020: Designated as a Ramsar Site (Site no. 2437), making it Uttarakhand’s first Ramsar Site and recognising it as a Wetland of International Importance.
Recent Developments (2026)
In January 2026, reports highlighted that recent snowfall and rain in Chakrata created favourable weather conditions, leading to an increased influx of foreign birds to Asan Barrage. Migratory birds from countries including America, France, Britain, Ireland, Norway, and Canada were observed at the wetland.
