Thanks for the response!
I need to do a little homework on what a water table is.
Because of the location, I would assume any other veins would have also be exposed.
The cold clean water has been flowing for 9 days since unearthing the area. The bottom of the pond wouldn't completely dry out. We just assumed it was poor trenching to the dam.
The hole, or earth spigot, is about 2" in diameter.
I will go out tonight and try to get a more accurate "pressure" determination. I will also see if I can feed a small line into the hole to determine it's depth.

I have an image but I cant figure out how to post it.
