Lake Natron is a Soda Lake situated ate the base of an active Ol Donyo Lengain Volcanic Mountain whereby the area around Lake Natron is often described as having a desolate and almost lunar beauty. The Lake is in the northern part of Tanzania with the nearest towns being Arusha of Tanzania and Magadi of Kenya. The lake is the most important breeding site for Lesser Flamingos in the world as East Africa has the population of 1.5 to 2.5 million of lesser Flamingoes which represent the tree quarter of the flamingoes population in the World, whereby Most of them are being hatched at Lake Natron. This is dues to the availability of plenty food, nesting sites and the lake is Isolated and undisturbed. Hence expect an abundant population of lesser flamingoes in the area. Moreover, the lake ecosystem provides the livelihood for the surrounding local communities.
Due to high evaporation, it has left the Natron with high Alkalinity whwreby the pH level can be greater than 12. The surrounding bedrock is composed of alkaline, sodium-dominated trachyte lavas that were laid down during the Pleistocene period. The lavas have significant amounts of carbonate but very low calcium and magnesium levels. This has allowed the lake to concentrate into caustic alkaline brine. This is what makes it to be the Soda Lake.
