The project was not welcomed by the local people during the conception and initial implementation of the project due to the displacement of 10,700 families and the way the government tackled the issue. Rengali Dam is 70.5 m tall and 1040 m wide. The reservoir formed by the dam is the second largest reservoir in Odisha, with 37,840 hectares at full level and 28,000 hectares at mean level. The reservoir has
22-774: A Ramsar Wetland of International Importance in 2002. About 62 mangrove species occur in the Bhitarkanika Mangroves, including Avicenna , Bruguiera , Heritiera and Rhizophora . Reptiles present in the mangroves include saltwater crocodile , king cobra , Indian python and water monitor . Between August 2004 and December 2006, 263 bird species were recorded, encompassing 147 resident and 99 migrant species. A heronry encloses about 4 ha (9.9 acres), where 11,287 nests were counted in 2006. Olive ridley turtles arrive in January to March for nesting at Gahirmatha Beach . An average of 240,000 nests per season
33-498: A catchment area of 25,250 km, mostly forests and wasteland. The dam is also used to generate electricity using five turbines with a capacity of 50 MW each. The dam holds 3412 million cubic meters of water at Full Reservoir Level (FRL). A barrage is constructed across the Brahmani river 35 km downstream of Rengali dam. The barrage is used to store the flood releases from the dam and divert it through two canal systems. It has

66-627: The Institute of Minerals and Materials Technology (IMMT) and the Spatial Planning and Analysis Research Centre Private Limited (SPARC) have performed a study on the 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
77-420: 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 the Mangroves if a sustainable amount of water is not released into the Mangroves. The Rengali Irrigation Project has come under
88-621: The project up to headworks [barrage]. The report had not been discussed by the Odisha State Assembly's Public Account Committee as of August 2008. 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."
