Lake Mweru

Lake Mweru lies in central Africa, on the border between Zambia and the Democratic Republic of the Congo. Its name simply means 'lake' in several Bantu languages, so many people just call it 'Mweru'.

The story behind it

Lake Mweru is part of the Congo River system and is the second-largest lake in the Congo's basin, after Lake Tanganyika. The Luapula River pours in from the south through a wide, swampy delta, and the Luvua River carries the water out to the north. On the western side, in DR Congo, a steep, rocky slope rises above the shore, while the land on the Zambian side in the east is mostly flat. Kilwa Island lies closer to the western shore, but it belongs to Zambia. Fishing is very important here: about 4 500 small boats, most of them built from wooden planks, go out on the lake. Fishers catch longfin tilapia, catfish and tigerfish. The explorer David Livingstone reached the lake around 1867 and called it 'Moero'.
