Have any of you ever built an outdoor pond? I'm curious whether I
really need to use 45 mil pond liner, or can I save $$$ and go with 20

I'm in NC, if it matters.


I have a pond and it does not have a liner. We dug it out by hand,
hold about 6000 gallons, fed by springs and overflow pipe to a brook.
The overflow has been running about 15 years, about 2 gallons a
minute.
