The Itaparica Reservoir, created by the Luiz Gonzaga Dam on the São Francisco River in Brazil, is a major body of water with ~830 km² of surface area used for hydroelectric power generation, water supply, irrigation, and recreation. Operating since 1988, it serves as a vital water source for the semi-arid region, though it faces environmental challenges like water quality degradation and eutrophication from urban sewage and agricultural runoff. The reservoir is also known for its socio-economic impacts, including the controversial Itaparica Resettlement Project and ongoing issues with artisanal fisheries and fish stock depletion.
