Баринго
The lake has not always been saline. Sediment cores from the lake floor have shown that freshwater conditions existed for several periods during the past 10 000 years, and that lake level was up to 9 m higher than its present elevation of about 990 m. At times it might have overflowed northward towards Lake Baringo. At times, during the late Pleistocene it might have been united with a larger precursor of modern Lake Baringo, but this is still uncertain.
