Lake Edward receives waters from many tributary rivers (Ishasha, Ntungwe, Nyamugasani, Rutshuru) and Lake George, by means of the Kazinga Channel. It empties to the north into Lake Albert, via the Semliki River. Lake Edouard - as well as the Ishasha river - marks the border between Congo (west) and Uganda (east). In this picture, the Semilki river is leaving Lake Edward flowing northward to reach the Lake Albert. © Lukski (Panoramio) - See the Impenetrable Uganda map with a complete picture set.
