WITH AN AREA of 26,830 square mile (69,490 square kilometer), Lake Victoria is the largest lake in Africa and, after Lake Superior in , the second largest lake in the world. At 3,720 foot (1,130 meter) above sea level, Lake Victoria is bordered by Uganda, Kenya, and Tanzania. It is 209 mile (337 kilometer) at its greatest length and 150 mile (240 kilometer) at its greatest width. Lake Victoria is located between 2 ranges of the Great Rift Valley on a depression with 250 foot (75 meter) at its greatest depth. Also known as Victorian Nyanza and, during the period of Arab influence in the 18th and 19th centuries as Ukerewe, Lake Victoria is fed by a multitude of rivers and streams, the most significant being the Kagera River. Lake Victoria flows into the Nile River and begins a very long journey to the Mediterranean Sea. The rather shallow but huge lake is located near the equator; evaporation from Lake Victoria is significant and influences the climate of central sub-Saharan Africa. Lake Victoria has hundreds of small islands, especially along its northern (Ugandan) shore. Small fishing villages abound, and many people are supported by an economy based on Nile perches, tilapia, and omena. In the swamps and marshes of the northern shore, the Sitatunga antelope thrive.
