evidence: Amos Mugisa, the LC1 of Rukorra in Bweramule sub-county, Ntoroko, says the shifting of River Semliki has reduced the territory under his charge by about five square kilometres. [...] Semliki River, which originates from Lake Edward, with some of its tributaries from the Rwenzori mountains and the DRC, on its 140km journey, flows through the Rwenzori foothills and pours into Lake Albert. [...] That is why they agreed that Semliki should be the recognised boundary separating Uganda and the DR Congo. The shifting of the river is now creating a puzzle on the borders.
