The Furnas Dam (Portuguese: Usina Hidrelétrica de Furnas) is a hydroelectric dam in the Minas Gerais state of Brazil. A small settlement was built near the dam with the same name to house the workers during the dam construction. The main purpose of the dam and reservoir are the production of electricity and the regulation of the flow of the Grande River. Near the beginning of 2022, mass amounts of rain caused a large rock to fall and kill 10 people.
