Thank for your replies. Those are really nice resources. I may get that laminated topo map that they are offering, so I have it on hand without a computer.

I am about 30 min from TAMU. I have to go down there one of these days and meet some of the people.

Now for the next step, would you know of a site that automatically calculates acre of watershead either by selecting a low point, or by outlining an area?
