I figured putting up beside the deck is a reasonable solution, but it has it's drawbacks too.

1. It's not private there
2. I don't see an obvious way of creating a decent waterfall - I can build up but I'm not seeing it look natural
3. The entire placement just won't look natural to my eye
4. It's not private there

If it's my only option, I will put it up there and I'm sure I would still love it. How would you go about doing a waterfall there? Just build up with rocks basically?

And Daryl - if you read the thread I'm open to an earth bottom pond, but don't really understand how to make it not be a small deep hole with water in the bottom. I don't know how you keep the water in there. I'm trying to learn though.

And don't presume to understand my relationship with "nature". What is even more natural about digging a hole to look at the water down there vs. throwing a piece of liner in the bottom? "Nature" puts liners all over the place...

Let's go back to what was part of your original question.......What will be the expected maximum thickness of winter ice? I am sure that there are local governmental sources that can answer that a lot more accurately than most of the members of this forum. Two foot thick ice seems considerable to me, but being in Florida, what do I know about it, ice is something WE put in tea.

You may be able to get by with only a small portion of the pond being 3 feet deep. In that scenario, the effects of hydrostatic pressure should be minimal.

Whatever the thickness of the winter ice, keep in mind that a hole must be maintained in the ice for the duration of the winter to allow gas transfer both into and out of the pond's water column.

Im not a "pond guy" but couldnt you move the hole down hill a bit so the current water level is where you want the level in your pond, make it wider and deeper, and put a heap of stones in there. Im thinking like a shallow well.

Problem may be is this a spring or just water seeping out, that will dry up? If this pond is on a slope then its not the water table you have there. Water table would be at the very bottom of the slope.

Yeah I think here you have to assume it will freeze solid...we get thick ice. I'm not sure how that is handled around these parts.

I'm afraid there is nofurther down hill, and I agree, it's not the water table it's just spring saturation sort of. It will fully dry up...anotherreason a earthbottom makes less sense. I guess that's part of my pondering... Does a little water for a little while cause less damage or is pressure pressure? The irony is I had to go 150 feet on my well 40 feet away for a $9000 bill....

Yeah I understand and due to seasonal water table flucuations it likely won't work...just seems kind of ironic...I want a pond in my yard and I dug down and hit shallow groundwater...now I'm screwed, lol.

So, some further developments...turns out there is a giant rock about 2.5 feet down and the water was sitting on that rock. I'm hoping that as I dig wider I will find an edge to the rock and will be able to build a little drainage ditch beside the rock.

Interesting stuff, I find it fun.

Good thread, thanks, good info in there.

One good thing about having really rocky land is you don't have to buy rocks when building a pond...

Considering the fact that a good portion of Ontario is glacial moraine, your "rock" may be the size of a soccer stadium or larger. I suspected that this was the problem when you mentioned that the water seepage was only a Springtime occurrence. You will probably find the same type rock under the larger wet area that you mentioned.
