The Barragem de Duas Unas (Duas Unas Dam) is a freshwater reservoir located in the city of Jaboatão dos Guararapes, Pernambuco, Brazil, situated along BR-232 in the direction of Recife to Caruaru. As the largest freshwater reservoir in the municipality of Jaboatão dos Guararapes and the 4th largest in the Metropolitan Region of Recife, this dam offers an accessible and rewarding sport fishing destination just approximately 25 km from the Boa Viagem neighborhood of Recife — roughly a 50-minute drive. Despite its proximity to one of Brazil's major metropolitan areas, the dam sits in a peaceful rural setting surrounded by farms and ranches, offering anglers clean water, fruit trees, and abundant wildlife. The reservoir is well known for its healthy population of yellow peacock bass and is considered one of the closest viable freshwater fishing options to the city center of Recife.
