Lake Tana, Ethiopia - April 1991

[edit] image description

Considered the source of the Blue Nile River, Lake Tana is visible in this spectacular, low-oblique, west-looking photograph. Located in the central highlands of Ethiopia, Lake Tana, the country’s largest lake, covers 1400 square miles (3625 square kilometers). The lake is 47 miles (76 kilometers) long and 44 miles (71 kilometers) wide and sits at an elevation of 6000 feet (1830 meters) above sea level. Lake Tana has become sediment-filled because of many small streams flowing into it and area deforestation. At its southern end, the lake drains into the Blue Nile, which shortly thereafter [6 miles (9 kilometers)] plunges over the Tisisat Falls and turns eastward, then southeastward, into a series of rugged canyons.
