My cousin just sent me some information about how parts of SoCal are looking to the northern half of the state for water. Obviously, with their drought, the folks up north don't feel like sharing .

We have already over-appropriated the Colorado (AZ,NV, and SoCal need the water), Texas and the lower midwest have sucked their aquifers way down, South Florida is now having saltwater pushing into the groundwater they use. Lots of folks not only want and need water but look at how many people live in those areas and how much political power (Federal) they are growing.

It won't be too long before we see fairly serious proposals to tap the Columbia, Great Lakes, and any other source of freshwater to support those areas. And, there is precendent. When San Francisco wanted water they got Federal approval to suck it out of a national park.
