I never heard of this word, potamic. As I save the old messages, maybe I'll make time somewhen to go through and count the words I think I knew before they were sent out and those that were very new to me (lottuvem).

In the same vein, er ... a ... streambed ... as the question "What size collection of buildings and people minimally constitutes a city?" ....

I've always wondered "What is the difference between a creek and a river and a stream?"

I've seen some "rivers" that were tiny little things that you could nearly wade across at parts - but they're called rivers. Is it gallons/liters per minute that flow? Some other criteria?

Example: The Salt River, which is clearly what I'd call a river down near where it joins the Ohio, but say up near where it was damned up to make Taylorsville Lake it was just a trickle some summers.
