Uganda and Kenya – December 4th, 2012

Several lakes can be seen by the Uganda-Kenya-Tanzania (clockwise from lower left) border area. Visible at the lower left is Lake Victoria, the largest lake in Africa. To its north is the irregularly shaped Lake Kyoga. In the upper right corner is Lake Turkana, colored by algal growth and sediments, some of which enter from the Turkwel River, which can be seen flowing across Kenya and into the southern part of the lake, on the western side.

Lake Turkana in Kenyan Rift Valley

Kenya and Ethiopia - December 25th, 2011

Lake Turkana is located in the Kenyan Rift Valley, with its far northern end crossing into Ethiopia. It is the world’s largest permanent desert lake and the world’s largest alkaline lake. Three rivers (the Omo, Turkwel and Kerio) flow into the lake, but lacking outflow its only water loss is by evaporation. Here, sediments give the northern part of the lake a tan color, while the rest changes from light to dark green due to different concentrations of sediments and algae.

Lake Turkana is an East African Rift feature. A rift is a weak place in the Earth’s crust due to the separation of two tectonic plates, often accompanied by a graben, or trough, in which lake water can collect. The rift began when East Africa, impelled by currents in the mantle, began separating from the rest of Africa, moving to the northeast. Currently the graben is 320 km wide in the north of the lake, 170 km in the south.

Tanzania - January 16th, 2011

Lake Turkana, formerly known as Lake Rudolf, is a lake in the Great Rift Valley in Kenya, with its far northern end crossing into Ethiopia. Here, the waters of the lake change in color as one moves from north to south.

There is a dark green wetlands area surrounded by tan sediments at the northern end, where the Omo River empties into the lake. The water gradually changes from tan to green near the middle of the lake.

Just below the center, on the west banks, the Turkwel River can be seen entering the lake. Here, the water gradually changes from green to bluish grey, at the southern tip.

Lake Turkana, formerly known as Lake Rudolf, is a lake in the Great Rift Valley in Kenya, with its far northern end crossing into Ethiopia. It is the world’s largest permanent desert lake and the world’s largest alkaline lake.

The climate is hot and very dry. On-shore and off-shore winds can be extremely strong as the lake warms and cools more slowly than the land. Sudden, violent storms are frequent.

Three rivers (the Omo, Turkwel and Kerio) flow into the lake, but lacking outflow its only water loss is by evaporation. Lake volume and dimensions are variable. For example, its level fell by 10 meters between 1975 and 1993. The water is potable but not palatable.

Despite the barren surroundings, the lake itself is a surprisingly rich if somewhat limited habitat for life, which on the lowest level manifests itself in an immense bloom of soda-loving algae, which can change its color from sky blue to jade green. The algae, in turn, support large numbers of fish.

Here, the waters of the lake and the rivers flowing into it appear white due to sun glint. A greenish algal bloom is present in the southern part of the lake.
