Semliki River is a territory of Uganda
Also referred to as Semuliki, River Semliki is the main River on the border of Uganda and the Democratic Republic of Congo and is about 140 kilometers (87 miles) long. With its source in Lake Edward (in Queen Elizabeth National Park on the Uganda-DRC border) and mouth in Lake Albert, River Semliki flows northwards within the Albertine Rift, west of the snow-capped Rwenzori Mountains. Along the lower banks of this River, it forms part of the International border between Bundibugyo District in western Uganda, near Semliki Forest National Park and the Democratic Republic of Congo. This river powers its waters into Lake Albert, west of the border in Orientale Province of Congo. [...] After leaving Virunga, River Semliki flows underneath another road connecting the Democratic Republic of Congo settlement of Oicha, through several settlements within the Semliki Valley, lying west of the Uganda-DRC border as well as Bundibugyo district (in Uganda) and along the western border of Semliki Forest National Park in Uganda. After leaving Semliki National Park, it nears the Toro-Semliki Wildlife Reserve before flowing west of the International border and also entering the southern end of Lake Albert at the spot southeast of Bunia (in DRC). [...] The Semliki River and Forest is inhabited by the Bakonzo and Bamba people who are mainly cultivators and the Batuku who are generally pastoralists as well as some Batwa pygmies who mainly survive on the waters of the meandering river. All these tribes have interesting cultures and customs that can be enjoyed during Uganda safaris.
