Pond Boss Forums POND CONSTRUCTION Building a dam Land bridge/walkway

My pond is a water table pond and the back side of it is shallow, about 2' max. The bottom is sandy with a few inches of organic material on top of that.

I'd like to build a land walkway over the top of this. It's about 50-60 feet in length, and I'd do the project in the summer when it's usually close to dry. I have access to cement blocks, both broken and whole. I was thinking about stacking cement blocks something like 3 wide and 3-4 high for the entire length. Then, maybe filling them, and over flowing them with some sort of settling stone.

Does this seem like a reasonable idea? Has anyone done something similar to this?

Sounds like a lotta work! I'm not 100% clear on what you are trying to do. Will the walkway allow the water to flow thru it? Or will you end up with 2 ponds, with one drying up every year?

Also unclear. What do you mean by over the top?

Yes, the walk way will split it to two ponds. The one will most likely dry up in the summer. What I'm trying to do is not walk so close to the neighbor’s back yard

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?

I doubt that the amount of leaching out from the wood would amount to much. I have trout in my pond, and treated an area with Cutrine Plus with no ill effects to the trout.

The rocks might not make it to the pond bottom, but I'll bet they will sink into the ground over time. What about using the rocks for the majority of the path, but a 6'-10' bridge to let the water flow between the 2 areas? Rock walkway on both sides, bridge in the center? You wouldn't need more than 9 posts, and that's a bit of an overkill depending on how wide you make it.

I never thought of a bridge in the center with a rock walkway on both sides. Not only would it allow water to pass under it, I think it would look really good too. Thanks for the idea!!

Anytime!
