Thanks
@Lisak1 , I'll cut your commission check later.
John j from Modern design aquascaping when he sizes his bogs in particular. He way over sizes it with probably 4 feet on all sides. That way the area that is doing the work is clear of having boulders over it thus cutting down the effectiveness of the bog. But it allows for a huge shelf for extra pockets for planting rock work and creativity.
I started with a simi circular design but the extra fabric in areas I kept hearing over and over don't cut someday you'll wish you had it. Well I turned that someday into while I was building and one of the results from this was the pitcher plant bog. Absolutely one of the most favored parts of my pond when people see it for the first time.
Brian helfrige aquascapes pond designer says over and over he will give a consult to the owner get a feel for what they want. But as far as this is exactly this or exactly that is never the case. You need to listen to your rocks. They will design the over all shape. They do talk to a builder. There's qusually one side that has the most character. But it may not look the best compared to others around it.
In my show case I put someone else's drawings showing some edge detailing to make a natural looking pond . Trust me even though there are like a dozen there that's hardly all there can be as most of mine differed from those.
When building you need to think like water. But in ponding there is also a usual traight. That being that without a pump or a sponge that water can actually lift upwards of 2 inches creating a leak. The absolute worst in ponding.
Folds in the EPDM can act like a straw and suck water up. No rubber does not absorb water but it happens . The other way is some plants are hollow and can do the same or they can act like a sponge and draw the water out.
Keep this in mind as you build and the rest is left to your imagination.
I will add all you boulders for shelves should come up higher than the shelf by at least 2 inches above or below the water line so these can hold back soil, The whicking we just talked about and underwater holding back gravel that you may place for the natural look.
