From a lazy 47 year old woman - sounds like a GREAT project! Unfortunately I know nothing about building or plumbing a foutain, so I'm hoping someone else will pipe up, especially those who have spliced liner (or overlapped). I'll be watching the responses!

Good luck!

Sounds pretty neat!
I've no info on roofing materials being used, but what you described (as far as the wall construction) sounds pretty close to what I've done using pond materials.
I have one side of my pond that looks like a bank of rocks - is this what you mean? Do you have any photos?

So long as the main liner peice comes up above the water line, I agree that the seam should hold. What I did in my case - was to have the one main peice of liner up above the water line and then I just tucked a peice behind this with no glue or bonding. This is simply to keep the dirt from going into the pond. If the pond level raises enough, I have a spillway on the opposite side of the pond that keeps the water from going behind the main liner on the high side. The key to something like this is maintaining the water level.
The one thing I can tell about this project - because I had quite a lot of trouble with it myself - is to make sure that you have the liner on the high sides well above the soil or you'll get some very muddy water. You may consdier building something of a bog there, or digging down the dirt to a good 3 inches below the edge of the liner, then filling in with gravel or mulch to keep the dirt from running into your pond when it rains.
As far as the drain spouts go, it sounds okay to me, so long as the rain water is coming from a "clean" source. Menaing, not the street or other peoples yards. Lawn chemicals and car pollutants can be dangerous to fish - but this sounds like it'll just be coming from the roof of your house so I think it'll be fine. Someone else may know of some hazzard that I don't though - I've never heard of this before.
This sounds fascinating! I'd like to see pictures when you have them!

As for pumps and hardware, there are simply loads to choose from. I use a very basic pump/filter that can be easily pulled up and carted off inside when it comes time for storing. No skimmer, no skippy, no UV filtration. But from the sound of it, your pond is going to be quite bigger than mine so you might need that stuff. Someone else may be able to give you a better idea!
Good luck, and let us know how it goes!

Thanks ever so much for taking ten years off my age. LOL.

Yep. Bank of rocks sounds just what Im workin on. I want to see rocks around the edge not liner.

I see you put your extra liner behind the main liner. The reason I put mine on top was because everything drains toward my pond. I was afraid all that water would go underneath my main liner and wash out my base or cause it to float. Its partly glued so Im stuck with it that way. There will be big fat flat rocks and boulders so the dirt wont be close to the edges. Hopefully the pond wont get muddy.

I looked up the roofing stuff Im doing my seams with incase you want to try some. Neoprene flashing cement. It says remains flexable and water tight. May be applied in standing water. We will see about that. LOL.

I live in the country. There are no chemicals coming from my patio unless you count bird poop. I must have 400 starlings. My cats are useless.

It will be a while before I finish.But Ill try for pics then. Im kinda web challenged. The inside rock bank should go pretty fast. Those rocks are small. When I get to those big suckers Im putting around the edges Ill be down to one or two a day tho. Moving boulders is hard work. LOL. Im addicted to rocks. The bigger the better. LOL.

Im not buying the fountain until the pond and edges are done. Hopefully by the Ill be abe to figure out the mechanicals. I figure the pond will tell me what kind of fountain it wants when its done. Who knows maybe it wont even want one. ;-)

I saw your pond. Looks like you put a lot of work into it. Very nice.

stanlie,

Brutal, but with good intentions.

"Where the pond is located there are two down spouts that currently will drain into it. And the patio slopes/drains that way too. I can reroute the down spouts if needed. But Im thinking if I let them go in and do an over flow

then the pond will flush itself every time it rains. What do you think."

I hate to "rain" on your parade BUT, this is how I see it.

Every time it rains, it washes the CRUD off your roof (leaves - bird droppings - etc.) into your pond and settles there. Eventually it fills with this crud (the heavy stuff settles - the lighter stuff floats/travels until, it too, gets caught up. Making for one big contamination concern (still water festers).

I see a lot of climbing in there and mucking it out.

Sorry, that's how I see it.
re-direct the spouts.

If you havn't already dug your rock ledge I wouldn't make it so deep. It takes alot of stacked rock to hide the edges of the liner--mine was 16" deep in places and I wish I would have made the rock shelf only deep enough so that part of the rocks would be submersed in water. It does enable me to put plants in between the rocks on the shelf though. What is "bug dust"?

Stanlie, it sounds like a wonderful project! Now, here's just one bit of advice from a somewhat hyperactive, rock-addicted 56-year old woman:

Roll the fountain into the basin before you do those rock wall edges. Or, at least on one side.

:) Mary

PS And, for a second bit of advice, stick with the slow rock moving program, give your hands rest in between, and if they feel inflamed, take rest and advil or something. I have had cortisone shots in both hands and two minor surgeries on my dominant hand because I didn't take a bit of inflammation seriously... (it's called trigger fingers and is caused by over-using the poor hands for hard work) (like rock walls and rock edges...)

Well that answers that question. No mucking. So I will be rerouting downspouts. Besides thats my varmits water bowl. I dont want to poison my felines. LOL

Too late now everything is already dug. Besides I have a lot of smaller scrap rocks left over from the dry stack wall I built around the patio that Id like to use up.

Bug dust is kinda like really fine gravel mixed with powdered gravel. Its used as a base for drives and patios and stuff.

Hey. A fellow rock junkie. OH I know all about the rolling part. It seems no one else around here likes to rearrange rocks but me. LOL. Heres how I woman handle mine. I have a good heavy weight hand truck for the small to medium ones. For the larger ones I have a bunch of building jack pipes. I lay 3-4 pipes on the ground then I use a spud bar and a crow bar to roll the rock forward. Remove back pipe, place in front. Repeat till you get where youre going. I got some 2x12s to lay down for the soft spots.

I plan on going slow. I think when you hurry you dont do a good job. I built my wall in 2-3 ' sections. Besides my rocks are "special". They need to be placed just so. ;-) Also I absolutely hate the heat. So I work outside in bursts then I retreat to work inside in the airconditioning. LOL.

I hope youre doing better after your surgury. I would sure miss not being able to do all my "projects". I dont have to take anything yet. My finger wont bend and sometimes it locks. But I can work around it. Im putting surgury off until I have too. ;-)
