Because of the many waterfalls and rapids, the various sections of the Kagera River basin are clearly separated, making movements by fish between them difficult or even impossible. Genocide During the Rwandan genocide of 1994, the Kagera was used to dispose of corpses as thousands of Tutsis and Hutu political moderates were murdered on the river banks. The river brought the massacred bodies into Lake Victoria, creating a serious health hazard in Uganda.
