Drangme Chhu
The 883rd longest river in the world
The Manas River (pron: [ˈmʌnəs]), known in Bhutan as the Drangme Chhu, is a transboundary river in the Himalayan foothills between southern Bhutan, India, and China. It is the largest of Bhutan's four major river systems, with the other three being the Amo Chu or Torsa River, the Wang Chu or Raidak, and the Puna Tshang Chu or Sankosh. It is met by three other major streams before it again debouches into India in western Assam. The river flows for a total length of 400 km (250 mi), including through Tibet for 24 km (15 mi), Bhutan for 272 km (169 mi), and Assam for 104 km (65 mi) before it joins the mighty Brahmaputra at Jogighopa. A major tributary of the Manas, the Aie, joins it in Assam at Bangpari. The Manas river valley has two major forest reserves, namely Royal Manas National Park (43,854 ha (108, 370 acres), established in 1966) in Bhutan and the contiguous Manas Wildlife Sanctuary (established at 391,000 ha (970, 000 acres) in 1955 and increased to 95,000 ha (230, 000 acres) in December 1985), encompassing a Project Tiger reserve, an elephant reserve and a biosphere reserve, which constitutes a UNESCO World Heritage Site declared in December 1985.
