One of the members of my brain trust was speculating idly the other day about how different the Colorado River dialogue might be if the hydro-geo-chemistry of the bathtub ring was different – if the dropping water didn’t leave a white mark, letting you see how much Lake Mead has dropped, letting people like me take a picture to put on my blog.

Standing atop Hoover Dam last week, I heard one of the Bureau of Reclamation tour guides emerge from the elevators, pointing out the bathtub ring and saying:

I don’t think as long as I live I will ever see it get to the top again.

I’m sure he or she does not speak for the Bureau and the Secretary of the Interior on this sensitive point.
