Mandraka Dam, dam in Mandraka, Analamanga Region
Mandraka Dam is a gravity structure in the highland region of central Madagascar that creates a small artificial lake lying about two hours east of Antananarivo. The water is surrounded by rolling hills and steep gorges, with shores lined with grasses and reeds, while a controlled outlet powers the nearby hydroelectric plant.
French engineers began construction in the late 1950s, completing the initial phase in 1956 and finishing the full project by 1972 to supply electricity to Antananarivo. After Madagascar gained independence, the facility's capacity was increased to deliver more power to the growing region.
The lake serves as a gathering place where families come for weekend outings, picnics, and swimming in designated areas. Local fishermen rely on these waters for tilapia and carp, which they sell in nearby markets and use to support their communities.
The best time to visit is during the dry season from May to October when the winding roads are safest and views are clearest. Guided tours are available on-site, and small hotels and restaurants nearby make it easy to spend time exploring the area.
The lake sits at about 1500 meters elevation and is surrounded by rocky hills of granite and volcanic stone that give the place a dramatic appearance. Visitors often notice the nearby Mandraka Falls, a popular spot for photos and the cool spray it creates.
