2. "One of Africa’s Biggest Dams Is Falling Apart"

Mosul Dam’s predicament is partly a result of the ongoing war; many maintenance workers have not returned there since August of 2014, when ISIS fighters briefly took control. (Iraqi and Kurdish forces soon regained it.) But the main issue is that, like many such dams, the project shouldn’t exist in the first place. Opened in 1986, it was built on unstable gypsum bedrock, requiring grout to be constantly injected into the foundation to prevent the dam’s collapse. That work has ceased. In 2006, long before ISIS began making headlines, the U.S. Army Corps of Engineers called Mosul Dam “the most dangerous dam in the world.”
