Forgot--here's a pic with some details. The grey ovals are flagstone, square white centers are cinder blocks, squiggley gray area is walkway.

This may be slightly OT but I share your concerns with pond liners and was wondering what other options there are for making a pond more water retentive?
and a frog and toad habitat might help for a lot of other uses and control mosquito population as well.
We have many ponds around, no fish, just frogs/toads and not more mosquito's than elsewhere. But then again im in the netherlands, water country....
My pond is about 50 to 75 ' away from my house (haven't measured but am guessing on that )
and it is about 6' below the grade level of our crawlspace and drainfield area..
I don't think I would want it closer..however if it was a lined or contained pond I wouldn't mind it being closer, have actually seen them within a few feet of a house, similar to a pool.
I think I would go at least 20 ' minimum and maybe more
So I dug a bunch of blobs of clay out of an area a bit away from the house, and the water drained in, and now it looks like this;
The question you really want to be asking is "What happens to the water in the pond if it leaks out?"
You should have foundation drainage that keeps your basement dry. You should have foundation sealant that keeps your basement dry. You should have landscape grading that keeps your basement dry. And you should have gutters, downspouts, and drainage lines to move roof water away and keep your basement dry. A wet basement means mold and rot, bad for the residents and bad for the structure.
Once you've done that, if you have a moisture point source somewhere in the area of your house, you can mitigate it with a drain that leads away to a swale or dry well.
How do you plan that the water will enter the pond? If it enters by groundwater seepage, then your water table is too high and either you shouldn't have a pond there, or you shouldn't have a house there. Pick one.
On the other hand, if your pond is acting as a rain barrel, taking rain off the roof and draining through an overflow to some safe disposal or use, you're golden.
You could, for instance, put a pond in a liner over top of a sand and gravel drain. The liner could even be several inches of clay, rather than a buried plastic layer.
But you don't want a hole that collects water and holds it where it will slowly seep into the basement, keeping it continually wet. How far the moisture source is matters much less than how permeable the ground is.
If you have a mortgage lender, they will take action to stop your plans if they hear about them. If they find out after the fact, they well mandate very expensive remedial actions.
You are correct, sir. Even if I want to replace an electrical outlet, I have to hire an electrician who will apply for a permit and pay a fee before any work is completed. Yes, I know these things. I got a permit for my fence, but digging the equivalent of a 55 gallon pond is not going to throw red flags in my neighborhood, especially when it can't be seen from the street, and later will be even more secluded behind swales. When you move into a low-income neighborhood and start installing nice fencing, cleaning up the whole property, and knowing and waving to your inspectors when they drive by, things aren't quite as political and stressful. Now this isn't a thread about legality or policies--I want to stay on topic.
