From Al Arabiya News as of 20 December 2014and thanks to the tip from Daniel:

 "Iraqi Diyala residents face ISIS ‘water war’"

An Iraqi official warned on Saturday of a “humanitarian disaster” after Islamist militants diverted Al-Roz River away from Bildoz district in the eastern province of Diyala, affecting thousands of people in what he described as a 'water war,'”

“'ISIS, for the fourth consecutive day, diverted Al-Roz River, considered to be an essential water source to Bildoz, and supplying drinking water to 150 thousand people as well as irrigating vast areas of land,' . . .  'thousands of people in Bildoz and other adjacent areas will be affected if water is not returned to its previous course into the river.'”

NOT only is ISIL controlling dams but also regulating the flow of water as an intimidating factor. A warning is being sent and heard loud and clear.

THAT ENGINEERING CORPS OF THE SADDAM HUSSEIN IRAQI ARMY NOTED FOR THEIR EXCELLENCE AT DIVERTING WATER TO CREATE BARRIERS AND OBSTACLES.

For 5,000 years water obviously so essential to any sort of civilized living in that part of the world, and eveyone knows it. Either deny or create an inundation literally of Biblical proportions and you have disaster.
