BARINGO, a lake in Kenya Colony, o° .46' N., 36° 15' E.; situated 3,15o ft. above sea-level. It can best be reached from the railway at Nakuru, 78 miles away. The lake is about 18 miles long by so broad. It occupies a portion of the floor of the eastern branch of the Rift Valley, and has no outlet. To the north are the Karosi Hills ; to the east the ground rises in ter races to the top of the Laikipia escarpment, while on the western side of the valley are the Kamasia mountains. The lake is fed by several small streams from the neighbouring hills. The Tigrish and the Nyuki flow in from the south, through a low marshy country, which yields good crops of maize. The existence of the lake was first reported about 185o by two German missionaries, Krapf and Rebmann. The first European to see it was Joseph Thomson in 1883. Native tradition says that the lake formerly occupied a much larger area.
