The Cachoeira dos Patos Dam (Portuguese: Barragem de Cachoeira dos Patos}) is a proposed hydroelectric dam on the Jamanxim River in the state of Pará, Brazil. Work has been delayed due to concern about environmental impact and lack of consultation with affected indigenous people.
The Cachoeira dos Patos Dam is proposed to be built on the Jamanxim River in the state of Pará, in the Tapajós river basin. It would be built in the municipality of Itaituba. The hydroelectric power plant will be part of the proposed 12,000 megawatts (16,000,000 hp) Tapajós hydroelectric complex on the Tapajós and Jamanxim rivers. Others are the São Luiz do Tapajós (6,133 MW), Jatobá (2,338 MW), Cachoeira do Cai (802 MW) and Jamanxim (881 MW), all under study, as well as the Jardim do Ouro (227 MW) and Chacorão (3,336 MW).
The Cachoeira dos Patos reservoir would have an area of 11,700 hectares (29,000 acres). The hydroelectric plant would have capacity of 528 megawatts (708,000 hp). Estimated construction cost is US$ 829 million.
The project would be undertaken by a consortium of Eletrobras, Eletronorte, Construções e Comércio Camargo Côrrea, EDF Consultoria em Projetos de Geração de Energia, Endesa Brasil, EPP Energia Elétrica, Promoção e Participações, Intertechne Consultores Associados and Neoenergia Investimentos. A "platform" approach is proposed for construction to minimise environmental impact. There would be no access roads, and workers would be taken to the site by helicopter. After construction is complete the site would be regenerated.
The Cachoeira dos Patos reservoir would flood 9,000 hectares (22,000 acres) of the Jamanxim National Park and 360 hectares (890 acres) of the Jamanxim National Forest. It would also affect the area around the Tapajós Environmental Protection Area and the South Amazon Ecotones Ecological Corridor. A study released in December 2015 took into account carbon and methane emissions from the reservoir and from construction and concluded that there was a high probability that the plant would generate emissions comparable to a natural gas plant.
