Marimbondo Dam

Marimbondo Dam is a massive embankment structure stretching across the Grande River with eight power generators that produce electricity for the region. Nine large spillway gates manage the water flow and regulate how much water moves downstream.

Construction started in 1971 as part of Brazil's expansion of power generation, with all units becoming operational by 1977. This project was part of the country's broader drive to modernize its energy infrastructure.

The dam reflects Brazil's large-scale approach to energy production and remains a symbol of national infrastructure development. Walking along it, you can sense the scale of engineering that powers homes across the region.

The site is located in São Paulo and can be visited from viewing areas along the structure. Bring sun protection and a hat as there is little shade on the dam and the sun exposure is intense in this region.

The reservoir behind the dam is one of the largest artificial lakes in the region, offering a striking view of the stored water. Nature enthusiasts and photographers appreciate the wide expanse and the surrounding landscape, especially during early morning or late afternoon hours.
