evidence: Semliki River, waterway connecting Lakes Edward and Albert, in the Western Rift Valley. It issues from the northwestern end of Lake Edward in Congo (Kinshasa) and meanders for 143 miles (230 km) north-northeast along the western foot of the Rwenzori Range to Lake Albert, the latter part of its course forming part of the border between Congo and Uganda. The Semliki has built up a considerable alluvial plain, part of which is included in the Virunga National Park. Wildlife, including elephants, hippopotamuses, crocodiles, and various kinds of antelope, is abundant. The river’s delta is choked with am batch (a fast-growing thorny tree) and papyrus; it is steadily encroaching on Lake Albert. Semliki River originates from Lake Edward found in Kasese District in Western Uganda. Lake Edward is found in Queen Elizabeth National Park on the border of Uganda and the Democratic Republic of Congo. The river flows northwards and empties into Lake Albert located in the Hoima District in Western Uganda at 1.2225°N 30.5038889°E. The river travels 230km along the Rwenzori Range and the border between Uganda and Democratic Republic of Congo from Lake Edward to Lake Albert [...] Semliki River forms the boundary between Uganda and the Democratic Republic of Congo. There is concern on the part of Uganda about the shifting border between Uganda and the Democratic Republic of Congo as a result of soil erosion. The Bundibugyo district leaders say that the river has shifted almost one kilometer into Uganda.
