The dam would flood 8,516 hectares (21,040 acres) of the Jamanxim National Park.

[3] The dam would be 72 metres (236 ft) high, containing a reservoir with an area of 7,445 hectares (18,400 acres).

The plant would contain 3 Francis turbines, handling a flow of 1,366 cubic metres per second (48,200 cu ft/s).

The project would be built by Eletrobras, Eletronorte, Construções e Comércio Camargo Côrrea, EDF Consultoria em Projetos de Geração de Energia, Endesa Brasil, EPP Energia Elétrica, Promoção e Participações, Neoenergia Investimentos and Odebrecht.

[5] A "platform" approach is proposed for construction to minimise environmental impact.
