Water spills from the West Bottom Outlet Tunnel at the Mosul Dam in 2018. The dam, with its the hydropower plant and four water storage towers, sits in a valley along the Tigris River approximately 30 miles outside Mosul City in Iraq. The dam is the largest in Iraq, and the fourth largest in the Middle East. It supplies water, hydropower, irrigation and flood control to the region. The Mosul Dam Project was a 3-year partnership started in 2016 as a joint venture among the Iraq Ministry of Water Resources, the U.S. Army Corps of Engineers, and Italian Company Trevi S.p.A. in an effort to stabilize and repair the dam, and update the infrastructure of the dam.
