Bog building, also called upflow filter, eco filter, wetland filter

@poconojoe For your spillway from bog to pond, do you just run a piece of liner from the lip, beneath the stones, and over the pond liner? Or do you just have one large liner for pond and bog? My pond is done, so the bog will have a separate liner

yOU CAN EASILY OVER LAP THE LINERS OR EVEN SEAM THEM TOGETHER . sorry for caps

@poconojoe just added his bog onto his pond so i'd bet it's overlaped

Thanks.

Yeah, I'm just way overthinking this whole thing.

No your not. a overlap of only a couple inches can leak as folds can wick water right up a couple inches even though rubber does not absorb water . ask away there's no dumb questions at one time we had no clue

@addy1 Just found your build in MD, not sure how I missed it before. lol
I wanted to ask you what you used for the wall between the bog and pond, wood logs? secured with rebar? and then just the liner over them? and rocks on the pond side to disguise? Your setup is amazing. Wish I had known about it years ago. I lived in Germantown MD for 7 years before coming to CO.

The wall is those landscape timbers, sort of round edges, 4ish inches wide. I don't recall how many we stacked up. I think 10 ish, I would need to find a pic and count. We did drill a few holes and drove in rebar, both ends have a 4x4 in concrete supporting the timbers on pond side.
The bog and pond liner is just one liner. The pond side of the wall is about 8 inches tall (out of water). The wall is about 2.5 feet tall, I glued some rock on the roll to the above water edge and have flat rocks on the top of the bog wall. a bit of liner shows here and there but not a bother.

The wall sits on a "shelf" which is about a foot out from the bog wall, we did not want the wood wall to sit right on the edge of the pond.

Here is a pic from bog looking towards our house. Between the yellow lines is the water fall rock.

My situation was like yours. I added the bog to my existing pond.

I just overlapped the new bog liner over the existing pond liner. It probably overlaps about 2 feet.

 

[poconojoe]

This is my overlap

And...when I started adding stones to hide the liner.

Yep, I too originally struggled with how to transition between the bog and pond.
I thought about it for a long time and then just went for it.

I think, maybe be sure your spillway is deep enough. You can always add more stones on top of the liner to get the look you want, but it would be awful tough to have to lift the liner back up if your spillway was too shallow.

Before the bog I had a waterfall there. The existing pond liner went up under the waterfall, so I had a bit of extra liner which I draped over the new bog wall.

See how green my water was?
After the bog add-on, it completely cleared up within a week.
It's been clear ever since.

Yep, not much to do when you have a bog.
Just feed the fish and enjoy.
No filter pads to clean.
