Hi,
We're expanding a small duck pond (small pond, the ducks are average sized) into something slightly less small (it's looking like it the pond itself will be about 6.5'x8.5' max depth 3'
The bog, which is partially raised(the bottom 6" or so are below pond level, the rest is above grade), will be about 3.5'x6.5'.
I can't do the math, but eyeballing it, it seems to be at least 30% of the total surface area.
I've been reading a lot but still have a few construction questions. Can I use earth or sandbags to build the retaining wall for the bog? It would be under the liner.
If so, how best to do this? We have piles of stones we can use over the liner, to hold things in place and to hide the liner. I'm hoping the ducks wont kick everything off.
Or - if I use pressure treated 4x4s (the other readily available option)....how best to close the gaps? I would be using short sections to create curves.
Also wondering how to build the waterfall section? We're planning for a maybe 8"drop and I'd like to direct the water over a large flat stone. I assume this needs to be lower than the gravel level. How do you direct the water over the stone?
I've read some things that say keep at least 2" of gravel above water level, but some things I've read say there should be standing water. My instinct tell me that standing water would reduce the effective filtration but maybe not? What's the general consensus on this?
Any other thoughts or suggestions before we get too much farther? Thank you!!
