Shallow lake, northwestern Botswana, north of the Kalahari Desert. It was a large lake, estimated at more than 170 mi (275 km) in circumference when the explorer David Livingstone sighted it in 1849. The lake varies in size with the amount of rainfall, and, although it is much smaller today than in Livingstone's time, it is rich in birdlife.
