The River Nagavali also known as Langulya is one of the main rivers of Southern Odisha and North Andhra States in India,[1] between Rushikulya and Godavari basins.

Origin and course

Nagavali River originates from a hill near Lakhbahal village in Thuamul Rampur block of Kalahandi District. It touches Nakrundi, Kerpai areas of Kalahandi, Kalyansinghpur and Rayagada of Rayagada district of Odisha and merged in Bay of Bengal near Kallepalli village near Srikakulam after crossing by the side of Srikakulam of Andhra Pradesh. It is an independent river with its own basin.

The total length of the river is about 256 kilometres (159 mi), of which 161 kilometres (100 mi) are in Odisha and the rest in Andhra Pradesh. The catchment area of the basin is 9,510 square kilometres (3,670 sq mi). Nagavali is an interstate river with 4,462 square kilometres (1,723 sq mi) and 5,048 square kilometres (1,949 sq mi) river basin area located in Odisha and Andhra Pradesh respectively. The river basin receives 1,000 millimetres (39 in) average rainfall annually. The yearly water availability in the river basin at Narayanapuram barrage is 1.117 billion cubic meters on average.[2] The uplands of the river basin are hilly areas with predominantly tribal populated. It drains parts of the Kalahandi, Rayagada and Koraput districts of Odisha and Srikakulam, Vizianagaram districts of Andhra Pradesh.
