U.S. Ambassador to Iraq Matthew H. Tueller speaks during a ceremony June 15, 2019, in Mosul, Iraq, held to commemorate the completion of the U.S. Army Corps of Engineers work supporting the Mosul Dam Project. The Mosul Dam Project started in 2016 as a joint project among the Iraq Ministry of Water Resources, USACE, and Italian Company Trevi S.p.A. in an effort to stabilize the infrastructure of the Mosul Dam. The Dam, which is the largest in Iraq, and the fourth largest in the Middle East, supplies water, hydropower, irrigation and flood control to the region. USACE's Mosul Dam Task Force acted as "The Engineer" for the joint endeavor.
