'''River Vamsadhara''' or '''River Banshadhara''' is an important east flowing [[river]] between [[Rushikulya]] and [[Godavari River|Godavari]], in [[Odisha]] and [[Andhra Pradesh]] states in [[India]].

The [[river]] originates in the border of [[Thuamul Rampur]] in the [[Kalahandi]] district and Kalyansinghpur in [[Rayagada]] district of [[Odisha]] and runs for a distance of about 254 kilometers, where it joins the [[Bay of Bengal]] at [[Kalingapatnam]], [[Andhra Pradesh]]. The total catchment area of the [[river basin]] is about 10,830 square kilometers.

[[Tourist attractions]] of [[Mukhalingam]] and [[Kalingapatnam]] in [[Srikakulam district]] are located on the banks of this river.

[[Mahendratanaya River]]<ref>[http://orissainformation.blogspot.in/2013/01/mahendra-tanaya-river-of-odisha.html?m=1]</ref> is a major [[tributary]] river of Vamsadhara originating in [[Gajapati district]] of [[Odisha]] and it joins Vamsadhara in [[Andhra Pradesh]] upstream of [[Gotta barrage]]. [[Regulapadu]] barrage in Andhra Pradesh is under construction to divert the river water for irrigation use.<ref>[http://www.thehindu.com/todays-paper/tp-national/tp-otherstates/article3794479.ece?textsize=large&test=1 Four years after laying stone river projects fail to take off - The Hindu 19 August 2012]</ref>

==Interstate aspects==
Vamsadhara river basin occupies 8015 square kilometers in [[Odisha]] and the remaining 2815 km<sup>2</sup> flows in [[Andhra Pradesh]]. The river basin receives high annual average rainfall of magnitude 1400 mm. The portion lying in [[Rayagada district]] of [[Odisha]] is predominantly hilly and [[tribal]] populated area. [[Andhra Pradesh]] and [[Odisha]] roughly estimated that 115 thousand million cubic feet (TMC) water is available for use in the river. They entered into agreements<ref>[http://cwc.gov.in/main/downloads/legal_instruments_3.pdf Agreements] with [[Odisha]] on Vamsadhara river waters sharing - pages 256 to 263</ref> to use the available river water in 50:50 ratio. [[Andhra Pradesh]] has taken up [[Gotta barrage]] and [[Neredi barrage]] projects to put its share of water for use. However [[Odisha]] has not taken up new projects in the basin area to utilize its share of water. In fact it is diverting Vamsadhara river waters to adjacent [[Rushikulya]] river basin by constructing [[Harabhangi dam]] without taking prior consent from Andhra Pradesh.<ref>{{cite web|url=http://india-wris.nrsc.gov.in/wrpinfo/index.php?title=Harabhangi_Dam_D02980|title= Harabhangi Dam D02980|access-date=20 April 2015}}</ref> Also, [[Orissa, India|Orissa]] has raised objections to [[Neredi barrage]] project on the grounds of land submergence in its territory during unprecedented floods.

Approximately 25% of the available water in this basin is being utilized during the monsoon season by constructing [[barrages]] across the river. Reservoirs up to 100 [[Tmcft]] water storage capacity are to be constructed for the non-monsoon period irrigation requirements, by which 100% water utilization can be achieved. Peculiar situation of this river is that most of the land to be irrigated is located in [[Andhra Pradesh]] while the possible storage reservoirs are located in Odisha. Vamsadhara River water disputes tribunal was constituted under [[Interstate River Water Disputes Act]]<ref>[https://www.scribd.com/doc/66801452/Interstate-River-Water-Disputes-Act Interstate river water disputes act - 1956 and its legal provisions]</ref> to resolve river water sharing issues between the two states. Justice Mukundakam Sharma is the chairman of Vamsadhara Water Dispute Tribunal.<ref>{{cite web|url=http://www.thehindubusinessline.com/news/states/vamsadhara-project-okayed-with-conditions/article5474710.ece|title= Vamsadhara project okayed with conditions|year=2013|access-date=20 April 2014}}</ref> The tribunal pronounced its draft verdict in September 2017 and permitted AP state to construct the side weir at Katragedda and Neradi barrage.<ref>{{cite web|url=http://mowr.gov.in/acts-tribunals/current-inter-state-river-water-disputes-tribunals/vansadhara-river-water-dispute|title= Vamsadhara Water Disputes Tribunal interim award.

==The Vamsadhara Project==
[[Boddepalli Rajagopala Rao]] Project was constructed on Vamsadhara river.<ref>[http://www.hinduonnet.com/thehindu/thscrip/print.pl?file=2007061453840400.htm&date=2007/06/14/&prd=th& The Hindu on Vamsadhara project]</ref>

Vamsadhara is the main river of [[Uttarandhra|North Eastern Andhra]]. The [[Uttarandhra|North Eastern Andhra]] region consists of three North Eastern Coastal districts in [[Andhra Pradesh]] state in [[India]]. Vamsadhara project is designed to meet the irrigation needs of [[Uttarandhra|North Eastern Coastal Andhra]].<ref>[http://www.vamsadhara.com Vamsadhara - Voice of Uttarandhra]</ref>

The [[Vamsadhara project]] has two canals viz., the left main canal (LMC), irrigating about {{convert|148000|acre|km2|-1}}, and the right main canal (RMC) covering an ayacut of {{convert|62280|acre|km2|0}}. The left main canal was completed long back. The right main canal was delayed due to various reasons. Gotta Reservoir feeds the right main canal. About 166 villages in seven mandals viz., [[Lakshminarasupeta|L.N. Peta]], [[Hiramandalam]], [[Burja]], [[Amadalavalasa]], [[Gara]], [[Sarubujjili]] and [[Srikakulam]] will be benefited from the RMC.

==Lower Vamsadhara Project==
The Lower Vamsadhara project envisages construction of 58m high & 1700m long dam across the vamsadhara river near [[Minajhola]] village (near {{Coord|19|31|00|N|83|44|30|E|type:landmark_region:IN-AP}} ) in [[Rayagada district]] creating hydraulic head of nearly 62 meters.<ref>{{cite web|url= http://www.ohpcltd.com/index.asp?type=sindhol#LVP |title= Lower Vamsadhara project, Odisha state |access-date=23 July 2013}}</ref> This project would be a multipurpose project serving power generation, [[irrigation]] and [[flood control]].

==Vamsadhara and Nagavali link canal==
A 30 km long gravity canal is planned to link the Vamsadhara and [[Nagavali River]]s.<ref>{{cite web|url= http://www.deccanchronicle.com/nation/current-affairs/050916/ap-plans-to-link-vamsadhara-nagavali.html |title= AP plans to link Vamsadhara, Nagavali|access-date=5 September 2016}}</ref> It will run from Hiramandalam reservoir to Narayanapuram barrage near [[Amudalavalasa]] and bring an additional 50,000 acres of ayacut under irrigation using 10 [[Tmcft]] of water from Vamsadhara basin.<ref>{{cite web|url= http://www.deccanchronicle.com/nation/current-affairs/050916/ap-plans-to-link-vamsadhara-nagavali.html |title= Hiramandalam Dam D03520|access-date=5 September 2016}}</ref><ref>{{cite web|url= http://india-wris.nrsc.gov.in/wrpinfo/index.php?title=Narayanapuram_Anicut_Medium_Irrigation_Project_JI00114 |title= Narayanapuram Anicut Medium Irrigation Project JI00114|access-date=5 September 2016}}</ref>
