Aruwimi River

The Aruwimi River (Swahili: Mto Aruwimi, French: Rivière Aruwimi) is a tributary of the Congo River, located to the north and east of the Congo. It begins as the Ituri River, which rises near Lake Albert, in the savannas north of the Kibale River watershed. The river flows generally southwest until it meets the Shari River near Bunia, then turns west through the Ituri Forest, becoming the Aruwimi where the Nepoko River joins it at Bomili. It continues westward and joins the Congo River at Basoko.

The Aruwimi River is about 1,287 kilometres long, with the Ituri being around 650 kilometres, the Nizi about 257 kilometres, and the Aruwimi itself roughly 380 kilometres. Where it meets the Congo, the Aruwimi is about 1.5 kilometres wide.

The area around the Aruwimi is mostly dense forest, with only a few villages along its course. The river was explored by Henry Morton Stanley during his 1887 expedition to help Emin Pasha. However, the cataracts above Yambuya made it difficult to travel by river, so the expedition had to move by land instead.
