The '''River Nagavali''' also known as '''Langulya''' is one of the main rivers of Southern [[Odisha]] and Northern [[Andhra Pradesh]] States in [[India]],<ref>{{Cite web |url=http://cwc.nic.in/Integrated_Hydrological_Data_2005/Integrated_Hydrological_Data_2005.pdf |title=Nagavali.CWC |access-date=12 April 2007 |archive-url=https://web.archive.org/web/20110721163524/http://cwc.nic.in/Integrated_Hydrological_Data_2005/Integrated_Hydrological_Data_2005.pdf |archive-date=21 July 2011 |url-status=live }}</ref> between [[Rushikulya]] and [[Godavari River|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 {{convert|256|km|mi}}, of which {{convert|161|km|mi}} are in Odisha and the rest in Andhra Pradesh. The catchment area of the basin is {{convert|9510|km2|sqmi}}. Nagavali is an interstate river with {{convert|4462|km2|sqmi}} and {{convert|5048|km2|sqmi}} river basin area located in Odisha and Andhra Pradesh respectively. The river basin receives {{convert|1000|mm|in}} average rain fall annually. 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]].

==Tributaries==
The main tributaries of the River Nagavali are Jhanjavati, Barha, Baldiya, Satnala, Sitagurha, Srikona, Gumudugedda, Vottigedda, Suvarnamukhi, Vonigedda, Relligedda and Vegavati. The Suvarnamukhi river takes its birth in the hills of [[Salur]] mandal and takes an eastern direction and finally join the Nagavali at [[Sangam, Srikakulam district|Sangam]] village in [[Vangara, Srikakulam|Vangara]] mandal of [[Srikakulam District]]. Vegavathi originates in pachipenta hills of [[Pachipenta]] Mandal.
*'''Vegavathi River''' takes its origin in the [[Pachipenta]] hills in [[Eastern Ghats]]. It is a tributary to Suvarnamukhi, which in turn is a tributary to River Nagavali. [[Salur]] town and [[Paradhi]] are located on the banks of this river. There are two [[road bridge]]s at these places.

==Towns and cities==
*[[Rayagada]] town and district headquarters of Rayagada dist of Odisha, River Nagavali flows in outskirts of the town.
*[[Srikakulam]] town, the district headquarters in [[Andhra Pradesh]]: River Nagavali flows through Srikakulam town and meets the sea at [[Kallepalli]] village, 5 kilometers far from Srikakulam town.
*[[Hatipathar, Rayagada|Hatipathar]], near [[Rayagada]]: It is a place of great scenic beauty with two waterfalls on the course of River Nagavali. The boulders here appear in a way that look like huge elephants.
