Haditha Dam.

This is coolbert:

ISIL insurgents advance on Haditha Dam. The capture of same would be most significant?

"Sunni Militants Advance Toward Large Iraqi Dam"

"BAGHDAD — Iraqi security officials said Wednesday that fighters with the Islamic State in Iraq and Syria were advancing on the Haditha Dam, the second-largest in Iraq, raising the possibility of catastrophic damage and flooding."
. . . .

"The ISIS militants advancing on the Euphrates River dam, about 120 miles northwest of Baghdad, were coming from the north, the northeast and the northwest. The fighters had already reached Burwana, on the eastern side of Haditha, and government forces were fighting to halt their advance"

I can recall that this dam was mentioned quite often during the American invasion of Iraq in 2003. A catastrophic release of water deemed as a possible Iraqi defensive measure, flooding on a Biblical scale an impediment to forward advance of U.S. armored units. But nothing ever occurred.

The control OF WATER RESOURCES IN THAT ARID PORTION OF THE WORLD ESSENTIAL TO SURVIVAL AND SUCCESSFUL RULE! As is well and intuitively understood.
