It is constructed across [[Brahmani River]] in Rengali village located 70 KM from [[Angul]] in [[Angul district]], [[Odisha]] in [[India]].<ref name="Hydrology and Water Resources in India">[http://books.google.com/books?id=ZKs1gBhJSWIC&pg=RA1-PA637&dq=rengali+dam&lr= Hydrology and Water Resources of India by Sharad K. Jain, Pushpendra K. Agarwal, Vijay P.]</ref> == Construction == Line 76: == Features == Rengali dam is 70.5 m tall and 1040 m wide. The reservoir formed by the dam is the second largest reservoir in ~~Orissa~~Odisha with 37, 840 hectares at full level and 28,000 hectares in mean level. The reservoir has a catchment area of 25,250 km<sup>2</sup> mostly forests and wasteland. The dam is also used to generate electricity by 5 units with a capacity of 50MW each. The dam holds 3412 million cubic meters of water at Full Reservoir Level (FRL).<ref name="Hydrology and Water Resources in India"/><ref>[http://angul.nic.in/water.htm Angul District official website: Water Resources]</ref> == Rengali irrigation project == Line 82: == Environmental impact == [[Bhitarkanika Mangroves]], located in ~~Orissa~~Odisha adjacent to Bay of Bengal faces a unique threat since the construction of this dam. The species of trees in the Mangroves are fed by the unique combination of salt and fresh water from rivers including [[Brahmani River]]. Scientists from [[Institute of Minerals and Materials Technology]] (IMMT) and Spatial Planning and Analysis Research Centre Private Limited (SPARC) have performed a study on ''Effect of reduced water flow through Brahmani-Baitarani river system on the mangrove population of Bhitarkanika estuary''. In their study, the scientists have found that the water flow at the Mangrove delta head before and after the construction of the dam in 1985 is 19,514 million cubic meters and 17,389 million cubic metres respectively. They believe that this level may go down to 14,000 once the full potential of the project will be realised around 2025. They have warned of slow decline and disappearance of the plant species in this mangroves if a sustainable amount of water is not released into the mangroves.<ref name="research of impact"/> == Performance audits == Rengali Irrigation Project has come under the scanner of India's apex audit institute twice. First, in Comptroller and Auditors General of India's report on ~~Orissa~~Odisha [civil] for the year ending March 31, 2000 on Paragraph 4.1 and again on CAG's report on ~~Orissa~~Odisha [civil] for the year ending March 31, 2008 on Paragraph 3.2. In 2000, auditors had looked at non-completion of the project, non-accrual of intended benefits and widespread mismanagement in paymet to contractors particularly with reference to construction of the project up to headworks [barrage]. The report had not been discussed by ~~Orissa~~Odisha State Assembly's Public Account Committee as of August 2008 [and probably till date]. In 2008, auditors noted that "due to delay in acquisition of land / nonacquisition of land, nonreceipt of forest land clearance and poor contract management, the project remained incomplete at various stages with investment of Rs 1695.61 crore (March 2008) resulting in cost overrun by Rs 1461.97 crore (626 per cent) and time overrun by 17 years."<ref>http://www.cag.gov.in/html/cag_reports/orissa/rep_2008/civil_chap_3.pdf</ref>
