Barragem do Paranoa: low-vis reservoir dive.
Barragem do Paranoa is a shore-entry freshwater reservoir dive in Brasília, built around thermoclines, low visibility, and a controlled training profile. It is better suited to divers who are comfortable with limited visibility and temperature layering, and it is often used for practice, night dives, and freshwater fish spotting rather than scenic open-water swimming.
