The Dam of Mabubas (Barragem das Mabubas, also known as Barragem Capitão Teófilo Duarte) is located northeast of the town of Caxito, in the Bengo province, Northwestern Angola. It is in the course of the Dande (or Dange) river and forms a large artificial lake known as Albufeira das Mabubas. It was built to generate hydroelectric power and to supply water to the city of Luanda, located about 70 km (44 mi). The construction of the dam began on February 18, 1948, and its first phase entered service in April 1954. The construction of the  second phase ended in May 1957.
