Desaguadero River (Bolivia and Peru)
The Desaguadero River, also known as Risawariru or Uchusumain, is a river shared between Bolivia and Peru. It drains Lake Titicaca from the southern part of the river basin, flowing south and draining approximately five percent of the lake's flood waters into Lake Uru Uru and Lake Poopó. Its source in the north is very near the Peruvian border. It is navigable only by small craft and supports indigenous communities such as the Uru Muratu community.
