Lack of water supply isn't just an issue in hot spots like Texas, Colorado and the Mississippi; it has also become a problem in the Northeast, where rivers are drying out in the summers and infrastructure developments are competing more for resources.
One of the area's biggest public universities, the University of Connecticut, needs more water. But plans to obtain it are generating controversy in a region where the availability of water is becoming more and more unpredictable.
Epic water battles are the stuff of history and legend, especially in the West. And as a severe drought drags on in the Midwest, a water war is being waged over a river that irrigates agriculture in Colorado, Nebraska and Kansas.
It's that last border crossing where this water war is under way. Kansas has gone to the Supreme Court to argue that Nebraska uses too much water from the Republican River, and that there's not enough left for Kansas farmers.
International ships call at the busy Port of New Orleans. It's a major shipping convergence point on the Mississippi River. Ships come upriver from the Gulf of Mexico with imports from abroad, and barges come downriver, bringing U.S. goods for export.
