The governments of Argentina and Brazil have revived plans for three new dams on the Uruguay River, a river already devastated by four dams upstream (Itá, Machadinho, Passo Fundo and Barra Grande) and the Salto Grande dam downstream.

If built, the Garabí dam — only the first of the three — would flood out 33,000 ha (82,000 acres) of inhabited land. Located along the border between the Argentine province of Corrientes and the Brazilian state of Rio Grande do Sul, Garabí would have a generating capacity of 2,800 megawatts.

The other planned dams are called San Pedro and Roncador. Environmentalists in both countries have vowed to oppose the dams.
