Land and Resources, Rivers and Lakes
The Zambezi River, along the northern border, is Zimbabwe's most important river. On the river, in the country's far west, is Victoria Falls, a spectacular waterfall where the Zambezi flows over a cliff into a narrow gorge. The Zambezi is navigable between Victoria Falls and the Cabora Bassa Dam in Mozambique. A number of smaller rivers, chief among them the Mazoe and the Sanyati (known in its upper course as the Munyati), join the Zambezi in the north. The Sabi River rises in the center of the country and flows into Mozambique (where it is known as the Save River). The Limpopo River forms the country's southern boundary with South Africa.
Kariba Dam is located on the Zambezi and houses a hydroelectric power station that serves both Zimbabwe and neighboring Zambia. The dam has formed Lake Kariba, a reservoir that is 282 km (175 mi) long and is a major source of fish and wildlife. A large number of smaller dams have been built throughout the country to provide water for cities or to support irrigated agriculture. There is extensive irrigation in the valley of the Sabi, and water from the upper Zambezi is used to irrigate the dry southwestern parts of the country.
