Ethiopia - July 4th, 2011

Tan sediments line the shores of Lake Tana, the source of the Blue Nile and the largest lake in Ethiopia, while the central part of the lake appears greenish in color.

Located in Amhara Region in the north-western Ethiopian highlands, the lake is approximately 84 kilometers long and 66 kilometers wide, with a maximum depth of 15 meters, and an elevation of 1,840 meters.

Lake Tana is fed by the Lesser Abay, Reb and Gumara Rivers and its surface area ranges from 3,000 to 3,500 kmĀ² depending on season and rainfall. The lake level has been regulated since the construction of the control weir where the lake discharges into the Blue Nile, which regulates the flow to the Tis Abbai falls and hydro-power station.
