Lualaba River

The Lualaba River flows entirely within the eastern part of Democratic Republic of the Congo. It provides the greatest streamflow to the Congo River, while the source of the Congo is recognized as the Chambeshi. The Lualaba is 1,800 kilometres (1,100 mi) long. Its headwaters are in the country's far southeastern corner near Musofi and Lubumbashi in Katanga Province, next to the Zambian Copperbelt.
