Among the report's case studies: Africa's Kariba Dam, the world's largest man-made reservoir, impounding 181 km³ of water. Almost $300 million was loaned in 2014 to repair the dam, with completion expected by 2023. The report says "Dams like Kariba will likely continue to operate much longer with recurring investments into repairs despite advanced age as they may be simply too large, risky, and costly to remove."
