River Tel which rises in the north of Nabarangpur district forms a sort of its geographical boundary with Kalahandi district and finally unites with a bigger Mahanadi river in Sonepur town. It is not perennial and dries up during the summer. The important river Indravati flows through Nabarangpur and beyond till it mergers with the mighty Godavari in Andhra Pradesh. It runs through a total distance of about 530 km out of which the Nabarangpur and Koraput districts contain about 130 km of its length. At Nabarangpur town the old girder bridge is replaced by a new span. Before reaching the Jagadalpur town in Chatishgarh state, it is joined by another river Bhaskal that drains the north of Nabarangpur. During the flood Indravati swells up to 450 ft wide and 24 ft deep. But a dam built for Hydro Electric Power circumscribes its flow and fury and at present it bears the vestige of its formal glory.
