Lesser Abay River Entering Lake Tana, Ethiopia13.2N 38.7E
The growth of algae and the presence of sediments causes Lake Tana (lower left corner) to appear light green in color. Entering the lake by the dark green area on the southwestern shores is the Lesser Abay River.
The lake is located in the Ethiopian highlands. The Semien Mountains can be seen to the northeast. To the east of the mountains is an artificial reservoir located near the town of Ozentari.
