Kariba Hydro Power & Dam: Testament To Rhodesian Ingenuity & Foresight Ahead Of The World
Editor: Imagine today an audacious engineering project, the greatest in its time, being completed ahead of time, under budget, at a quality commended for excellence and, for the benefit of all citizens without crippling debt because it paid for itself? Impossible! Yet Rhodesia did it, despite the challenges of:
-Mother nature hurling epic floods,
-Thousands of people and wild animals to carefully relocate,
-International sanctions curtailing access to materials, and
-A war against internationally financed Communist Terrorists at its peak!

A Marvel of Engineering
Kariba Dam was “Africa’s greatest mass of masonry since the Pharaoh’s built the Pyramids” declared the Sunday Mail on completion of the wall. On 17 May 1960, the Queen Mother officially dedicated the Kariba Dam by turning on the second generator. The Queen Mother hailed the Kariba scheme as:
“a marvel of modern engineering, which in the future may well rank with the seven wonders of the Ancient world.”
The Largest Man-Made Lake
In terms of volume, Kariba remains the world’s largest man-made lake, with a volume of 180.6 kmᵌ. Kariba covers an area of 5,580km². The height of the wall is 128 m and the length of the lake is 282 km.
Kariba Dam cost £113 million, but within the first ten years of operation, it saved 3.6 million tonnes of coal and 82 locomotives and 5,000 railway trucks which would have had to transport these Millions of tonnes of coal to power stations which themselves would have cost another £100 million. Kariba South, Phase 1, included six generators which produced 705 MW of energy. Kariba North, Phase 2, completed by 1977, added another 600 MW to its capacity.
Ahead of Schedule and Under Budget
9,000 people worked on the construction of Kariba Dam, which, despite two devastating floods in 1957 and 1958, with unprecedented volumes of water wrecking much work in progress of the structures, the Kariba Wall was completed ahead of schedule and £2 Million under budget!
Harnessing the Power of the Mighty Zambezi
Incredibly, the vision for constructing Kariba Dam began in the 1940’s, while war raged in Europe. Engineer J.L.S. Jeffares, the Father of the Kariba Hydro Electric Project, laid the groundwork for this far-sighted and way ahead of its time scheme to dam up the narrow gorge through which the mighty Zambezi River tore and to harness the hydropower that would save Northern and Southern Rhodesia the burning of a million tonnes of coal a year.
Cheap, Clean, Renewable Energy
The provision of cheap energy, at approximately 2c per kilowatt, made possible the tremendous economic and industrial growth of both Northern and Southern Rhodesia. Long before Aswan Dam on the Nile and other hydro-electric plans, Rhodesia pioneered the way in a wild land, sparsely populated by primitive people living in the iron age. Kariba was a feat unprecedented in history to provide cheap, reliable, clean and renewable energy for the benefits of all citizens in the Central African Federation. The people of Zambia and Zimbabwe continue to be the beneficiaries of this far-sighted and sacrificial endeavour and perseverance in the face of seemingly impossible adversity and insurmountable difficulties.
Kariba – Legacy of a Vision
Jonathan Waters has produced a magnificent 320-page, hardcover book with over 800 pictures: Kariba – Legacy of a Vision, which recounts all the drama, difficulties and dedication that produced one of the most practical foundations for economic growth in Central Africa, along with a major tourist attraction and marvel of the modern age.
