The Semliki River at Ishango, Virunga National Park, Congo (Democratic Republic)

"The eastern half of Lake Edward is surrounded by the Rwenzori National Park of Uganda. The western half, including the outflowing Semliki River, is encompassed by the Parc National du Zaire (Virunga National Park). The amount of water flowing through the lake, exclusive of evaporation, can be seen at the outflow via the Semliki River at Ishango in the northwest which is 30-40 m wide. The water leaves the lake as a rapid and turbulent stream about 3 m deep over rocks and boulders." This photograph was taken when Eliot Elisofon traveled to Africa from early March 1951 to July 1951, accompanied by his wife, Joan B. Elisofon.
