I've found that the NRCS offices (at least the ones near here) vary GREATLY in the amount of input and help that they will give a property owner that wants to build a pond. One county near here is great - they will come out, have equipment to take a 20' deep soil sample, etc. The next county over has no equipment, and you get about the same service that you got. And NO, they will not cross county lines - I tried years ago.
I was hoping you had a good office.....
