Lakes West of Bale Mountains, Ethiopia

6.8N 39.7E

January 20th, 2012 Category: Lakes

Ethiopia - January 4th, 2012

A cluster of lakes can be observed near the center of this image of Ethiopia (from north to south): Ziway Lake (green), Abijata Lake, the connected Langano and Shalla Lakes, and Lake Awasa. Visible further south is the tan Lake Abaya, located in the Main Ethiopian Rift, east of the Guge Mountains. Lake Abaya is 60 kilometers long and 20 wide, with a surface area of 1162 square kilometers. It has a maximum depth of 13.1 meters and is at an elevation of 1285 meters.

Visible east of these lakes are the Bale Mountains (also known as the Urgoma Mountains), appearing here as a large, dark area. They are a range of mountains in the Oromia Region of southeast Ethiopia, south of the Awash River. They include Tullu Demtu, the second-highest mountain in Ethiopia (4377 meters), and Mount Batu (4307 meters). The Weyib River, a tributary of the Jubba River, rises in these mountains east of Goba.

Cluster of Lakes Northwest of Bale Mountains, Ethiopia – March 12th, 2011

Ethiopia - February 10th, 2011

Many lakes are visible in this image of Ethiopia. Lake Abaya appears tan in color, in the lower left corner. Moving northeast, a cluster of lakes can be observed nearby (from south to north): Lake Awasa, Shala Lake, Abijata Lake (left), Langano Lake (right) and Ziway Lake. The lakes appear various shades of green due to differences in the concentrations of sediments and algae.

The dark green area of land in the lower right quadrant is the Bale Mountains (also known as the Urgoma Mountains), a range of mountains in the Oromia Region of southeast Ethiopia, south of the Awash River. The Bale National Park covers 2,200 square kilometers of these mountains. The park also contains the Harenna Forest, situated to the south of the mountains.

Ethiopian Rift Valley Lakes

Ethiopia - June 3rd, 2009

The Ethiopian Rift Valley lakes are the northernmost of the African Rift Valley lakes. Most of these do not have an outlet, and most are alkaline.

In central Ethiopia the Great Rift Valley splits the Ethiopian highlands into northern and southern halves, and the Ethiopian Rift Valley lakes occupy the floor of the rift valley between the two highlands.

At the top is Lake Koka, with a surface area of 250 km² at an elevation of 1590 m. The large green lake below it is Lake Zway, a freshwater lake of 485 km² at an elevation of 1636 m.

The brown lake below is Lake Langano, at an elevation of 1,585 meters and with a surface area of 230 square kilometers. Though its brown color may make it appear less inviting, it is free of Bilharzia (schistosomiasis), unlike all other freshwater lakes in Ethiopia, making it popular for swimming.

To its left is Lake Abijatta, with a surface area of 205 km², at an elevation of 1573 m. Along the northeastern corner of this lake are a number of hot springs.

Continuing south, the large dark body of water is Shala Lake. It has a surface area of 409 square kilometers, a maximum depth of 250 meters and an elevation of 1,567 meters. It is known for the sulphur springs on the lake bed and is surrounded by hot springs filled with boiling water.

Finally, the southernmost lake visible here is Lake Awasa, an endorheic basin with a surface area of 129 square kilometers. Despite its lack of an outflow, it is essentially a freshwater lake, indicating that it must have a subterranean outlet.
