The Mandal climbs in the eastern statures in Talla Salan in Chamoli area. Structuring a piece of the northeastern limit, Mandal streams for 32 km and joins the Ramganga at Domunda a little separation above Gairal. Amid the dry season, the Mandal contains almost no water however amid the rainstorm it transforms into an irate torrent. It structures an essential reproducing ground for the imperiled mahseer. The Palain is the third vital tributary of the Ramganga and enters the Park from a northern course. It meets the Ramganga around 3 km north of the Ramganga repository.
