The Ogalalla aquifer is disappearing. No one cares. When it is gone it will take 6,000 years to replace. At least we can always desalinate the oceans, and sell lots of sea salt, the latest sales gimmick.

> Let's not get into the question of what do we do when the artificial lakes behind the dams silt up. We use water stupidly, especially when dictated by a government.-That might be a little harsh... I've known guys in the Army Corps. If you let each state control flows without centralized management, internal politics could get pretty dicey: Imagine if North Dakota faced drought and decided to shut the gates? Everyone downstream would be negatively affected. -Water flow is too big a problem to not have some kind of national management system.
