Kariba Dam is located about 130 kilometers south of Lusaka. When it was built in 1959, on the border of Zambia and Zimbabwe, the Kariba Lake was created. It is 280 kilometers long and contains about 185 cubic kilometers of water. Its name, Kariba, means "trap". The Kariba Dam is 128 meters high and 579 meters long, in the shape of a double arch (curved along both the horizontal and vertical axes.) The lake serves as an accumulation for two hydropower plants - the southern, Zimbabwean of 1050 MW and the northern, Zambian of 960 MW. With the construction of this dam, ecosystems and human settlements of the entire downstream course have suffered damage, both due to dry and flood periods.
