Their names are not recorded in most accounts of Kariba Dam, but the concrete arch they raised between 1955 and 1959 still holds back the Zambezi River in a gorge between Zambia and Zimbabwe. Standing 128 meters tall and 579 meters long, the dam created Lake Kariba -- a reservoir stretching 280 kilometers and holding 185 cubic kilometers of water, making it the largest man-made lake in the world by volume when it filled. Queen Elizabeth the Queen Mother opened the dam on 17 May 1960. What she inaugurated was not just a power station but a fulcrum of southern African geopolitics, ecology, and human displacement whose consequences are still unfolding.

It would have been cheaper, less disruptive, and adequate for the region's needs. Southern Rhodesia, the w...

Kariba Dam: The Dam That Might Break

Decades of torrents from the spillway had eroded the basalt bedrock beneath the dam, carving a vast crater that undercut its foundations. If the dam failed, the Zambezi...

In January 2016, water levels dropped to 12 percent of capacity, just 1.75 meters above the minimum operating level for hydropower. By January 2023, levels had fallen to 1 percent of capacity, with output lim...
