Lake Tshangalele, also known as Lake Lufira or Mwadingusha Reservoir, is an artificial lake in the south-east of the Democratic Republic of Congo. It is located about 20 km east of the city of Likasi in the old province of Katanga. It lies at about 1,100 m above sea-level in a large depression surrounded by low mountains. It was created by a dam built on the Lufira River near Mwadingusha in 1926 to provide hydro-electric power. The area of open water is about 362.5 km². During the wettest months of February and March, the area flooded reaches a maximum of 440 km².
