Esshup, I fully agree with what you are saying. I have a very similar situation. I had to pump with a 4" line every day. For me, too early to tell how much it will fluctuate over the years, but it has been fluctuating some.

My question to Backstroke was kind of vague and short. My thinking is that if water isn't coming in now, then why not since the ground is so full of percolated water. And then if it is coming in, at what level is it stopping, because that may be the best it ever gets, or could fluctuate up and down tremendously. I don't want to say that the NRCS person is wrong, but if it was me I would do some outside homework to learn more about the situation to verify/deny. Even if no water is coming in now, will that mean when it does rain will the soil type just let it all drain out,... after all the area percolates!
