![]() While this lake remains deadly to most, it is still a vital ecosystem. The proposed construction of a hydroelectric plant on the Ewaso Ng’iro River and a soda ash plant on its shores threatens the lake’s salinity and the flamingos. If they spent any longer in the lake, they would have died.Ĭurrently, Lake Natron is under threat. It burned their eyes and skin, but they managed to drag themselves ashore. Lake Natron is a salt lake located in northern Tanzania, in the area of Arusha on the border with Kenya, and the eastern part of the African Rift Valley. Everyone survived the crash but they were in the water unprotected. In 2007, a helicopter carrying a group of wildlife videographers wishing to get footage of the flamingos crashed into the lake. People have occasionally survived the lake’s potency. Lake Natron would have saved pharaonic embalmers a lot of work. The ancient Egyptians used sodium carbonate and bicarbonate in the mummification process. Photo: Shutterstockįor most humans, the lake’s qualities are more suitable for the dead than the living. The lake doesn’t quite have that instant effect. The graphically eerie positions looked like the finger of Medusa had really touched them. Wildlife photographer Nick Brandt made headlines in 2013 by staging photos of the mummified remains of the poor creatures around Lake Natron. They drown in the toxic potion, and their outsides and insides calcify. The mirror-like surface tricks them into diving into the red waters for food. Some alkaline tilapia (a member of the cichlid family) can sustain themselves in the cooler parts of the lake.īut to some wildlife, especially birds, Lake Natron can be a death trap. Somehow, a few species of fish, invertebrates, and algae manage to live in the lake. In Lake Natron, their pigment paints the water a striking red. Generally, cyanobacteria carry different pigments. The lake’s salinity has welcomed salt-consuming, halophilic microorganisms called cyanobacteria, which need photosynthesis to survive. Lake Natron’s deceptively glassy surface. Its average alkalinity is 10.5, its pH surpasses 12, and its water temperature ranges from 40˚ to 60˚C. This concentrated the trona (sodium sesquicarbonate dihydrate) and natron (hydrated sodium carbonate) in the leftover water, creating a highly toxic brine. Since the lake had no outflow and received irregular rainfall, it endured thousands of years of intense evaporation from the heat. During the Pleistocene period, a rare type of lava rich in sodium and potassium carbonates ran down the slopes of the Ol Doinyo Lengai volcano and into the lake. It’s fed by the Southern Ewaso Ng’iro River in Kenya. This shallow but wide lake is just three metres deep but 22km wide. Tanzania has no less than four alkaline lakes, but Lake Natron is the most famous. Lake Natron is a hypersaline and highly alkaline lake located in the eastern section of the volatile East African Rift. In North Tanzania, a unique inland lake turns wildlife to stone. That’s a legend, but a natural wonder in Africa today does just that. ![]() We all know about the Greek monster Medusa, whose deadly gaze turned men to stone. As isolated as the lake is (it wasn't even discovered by Europeans until 1954), there are no protections in place for the lake or its threatened flamingo population.įollow Marc Lallanilla on Twitter and Google+. The serenity of Lake Natron - and its flamingo population - are threatened by a proposed hydroelectric power plant on the Ewaso Ngiro River, the main river feeding the lake. As shallow lakes in a hot climate, their water temperatures can reach as high as 106 degrees Fahrenheit (41 degrees Celsius). Both are terminal lakes that do not drain out to any river or sea they are fed by hot springs and small rivers. Lake Natron is one of two alkaline lakes in that area of East Africa the other is Lake Bahi. The flamingos' nests are built on small islands that form in the lake during the dry season. During breeding season, more than 2 million lesser flamingos ( Phoenicopterus minor) use the shallow lake as their primary breeding ground in Africa. ![]()
