The dam was constructed by the French Business Company between 1937 and 1938. It creates Lake Mantasoa which has a surface area of {{Convert|20|km2|mi2|abbr=on}}. The dam itself is made of {{Convert|8000|m3|cuyd|abbr=on}} of concrete and has a reinforced buttress design.[1] Water released from the dam supplies a regulated flow to hydroelectric power station at the Antelomita Dams downstream. A saddle dam on the north side of the Mantosoa reservoir regulates water flow into the Mandraka River for the Mandraka Dam downstream.[2][3] See also
