Lake Natron: Tours & Expériences
Es-tu déjà allé à Lake Natron?
Lake Natron is a salt or soda lake in Arusha Region in Tanzania. It is in the Gregory Rift, which is the eastern branch of the East African Rift.
The alkaline water in Lake Natron has a pH as high as 10.5 and is so caustic it can burn the skin and eyes of animals that aren't adapted to it. The water's alkalinity comes from the sodium carbonate and other minerals that flow into the lake from the surrounding hills. And deposits of sodium carbonate also acts as a fantastic type of preservative for those animals unlucky enough to die in the waters of Lake Natron.
Lake Natron is one of two alkaline lakes in that area of East Africa; the other is Lake Bahi. Both are terminal lakes that do not drain out to any river or sea; they are fed by hot springs and small rivers. As shallow lakes in a hot climate, their water temperatures can reach as high as 106 degrees Fahrenheit (41 degrees Celsius).
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 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.
