Can you find a way to sink treated 4x6 posts in the deepest part of the shallow pond where the walkway would be to allow some water flow between the two? To make a short bridge.....
What would prevent the rocks from slowly sinking down into the pond bottom over time?
I've thought about a bridge. Is there any concern with the treated lumber in the pond? I know they use copper, would the amount of copper hurt my trout? (I think trout aren't copper tolerant).
As for the rocks, will they sink into sand over time? The bridge would be a fair distance onto the "shelf" I'd be buiding on. If I stayed 10 feet away from the drop off, do you think the rocks would make there way to the pond bottom?
