The São Francisco River is one of the longest rivers in Brazil, stretching approximately 3,160 kilometers (1,960 miles). It flows through several states, including Minas Gerais, Bahia, and Alagoas, before emptying into the Atlantic Ocean. The river is vital for irrigation, fishing, and transportation in the region. Known as the "River of National Unity," the São Francisco River supports diverse ecosystems and communities along its banks. It is also significant for hydroelectric power generation, with several dams built to harness its energy, contributing to Brazil's electricity supply.
