The Baguari Reservoir is a water impoundment area on the Doce River in the state of Minas Gerais, Brazil, created by the Baguari Dam, which serves the Baguari Hydroelectric Power Plant. This 140 MW project utilizes four bulb turbines to supply power to Brazil's grid and includes a fish ladder, though studies on its effectiveness have noted challenges with fish attraction and passage, particularly for migratory species.
