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. The lake is shallow with a mean depth of only 2.6 m.
The lake holds a variety of fish
including longfin tilapia (Oreochromis macrochir), redbelly tilapia (Tilapia zillii), thinface cichlid (Serranochromis angusticeps) and North African catfish (Clarias gariepinus). It supports an important commercial fishery with the tilapia
s the main species caught. Surrounding the lake, there are extensive swamp
s where Typha
and Cyperus
grow. The region is rich in birdlife such as the Lake Lufira Weaver
(Ploceus ruweti) which is endemic to the area. The lake was declared a Biosphere Reserve
