The Teles Pires Dam is a hydroelectric dam under construction on the Teles Pires River, 330 km (205 mi) upstream of the confluence with the Tapajós river, on the border of the Brazilian states of Mato Grosso and Pará. The 80 meter dam will impound a 150 square km reservoir (55 km original river bed and 95 km inundated area), 84% in Mato Grosso state (Paranaita district) and 16% in Para state (Jacareacanga district).[1]

The dam is part of a planned six power plant "Hidrovia Tapajos/Teles Pires" project to create a navigable waterway connecting the interior of Brazil to the Atlantic Ocean. The waterway will consist of five dams on the Teles Pires river (53MW Magessi Dam, 430MW Sinop Dam, 342MW Colider Dam, 1820MW Teles Pires Dam, 746MW Sao Manoel Dam) and the 230MW Foz do Apiacas Dam on the Apiacas river.

The Teles Pires Dam is currently under construction, while the smaller upstream dams are still in the planning stages.[2]

Design[edit]

The Teles Pires Dam is a gravity dam constructed of composite materials layered on a Roller-compacted concrete core, located on the Teles Pires river, 330 km upstream of the confluence with the Tapajos river, on the border between the Brazilian states of Mato Grosso and Para [3]

Impacts[edit]

Brazilian law requires water impoundments to undergo a very thorough approval process to ensure that each project meets environmental, social, political, and safety criteria.

Social[edit]

The most frequent objection is that the dam builders failed to adequately consult with indigenous peoples, as required by law. The Brazilian government indigenous protection foundation FUNAI predicts that there may be un-contacted indigenous populations in the region that will be affected by the dam.[4] On March 30, 2012, a judge suspended construction of the Teles Pires Dam to preserve a waterfall that is considered sacred by an indigenous tribe [5]

Environmental[edit]

The Teles Pires Dam does not impound a large reservoir because it is a run-of-the-river project. The dam also feature significant environmental re-mediation efforts. As a consequence, there has not been strong environmental opposition to the implementation of the Teles Pires Dam.[6]
