Lake Natron
Lake Natron is a soda lake at the lowest point of the eastern section of the Great Rift Valley. The lake, which borders Kenya to the east, lies at an altitude of 600m above sea level. It is fed by mineral-rich hot springs and the Southern Ewaso Ng’iro River. It is shallow with a depth and size that change due to the high level of evaporation. “Natron” is the word for the mixture of salt and minerals left behind. The alkaline water temperature may reach 60 degrees c., depending on rainfall. The lake falls within the Lake Natron Basin, a Ramsar wetlands site of International Importance.
Because of its high temperature and variable salt content the lake does not support wildlife. However, it is the principal breeding site for the lesser flamingo, a near threatened species. Lake Natron’s caustic environment is a barrier against predators trying to reach their nests. Greater flamingos also breed here on the mud flats. Algae and tilapia, fish that survive in alkaline waters provide food. The land surrounding the lake is dry with sand rivers, rock hills, Masai steppe, acacia trees, and the active volcanic mountains Lengai and Gelai. A beautiful rocky river with waterfalls forms a natural oasis nearby. The area is ideal for mountain and river walks
