Explanation:

The Beas Conservation Reserve is a 185-kilometre stretch of the Beas River located primarily in the north-west of the State of Punjab. The River meanders down from the Himalayan foothills to the Harike Headworks, where its course is diverted into a number of channels. The River is dotted with islands, sand bars and braided channels creating a complex environment supporting substantial biodiversity. More than 500 species of birds are documented along this stretch, along with more than 90 fish species. The Reserve also hosts the only known population in India of the endangered Indus river dolphin (Platanista gangetica minor).
