The Tigris is heavily dammed in Iraq and Turkey to provide water for irrigating the arid and semi-desert regions bordering the river valley. In February 2016, the United States Embassy in Iraq as well as the Prime Minister of Iraq Haider al-Abadi issued warnings that Mosul Dam could collapse.[13] The United States warned people to evacuate the floodplain of the Tigris because between 500,000 and 1.5 million people were at risk of drowning due to flash flood if the dam collapses, and that the major Iraqi cities of Mosul, Tikrit, Samarra, and Baghdad were at risk.[14] ./cache/en-wikipedia-org-561.html ./txt/en-wikipedia-org-561.txt
