Wasn’t sure where to ask this question so I plunked it here. One of my ponds is used by my daughters as a swimming area. I have a small dock but would also like to have a clean and clear area to wade in from shore. The bottom is relatively clean. There’s a little silt over shale and clay. Firm bottom. I’ve thought about dumping some gravel maybe or sand. But also wondered if there are any other options? In my head it seems like there should be some kind of sinking mat that could be used for this purpose. I’d appreciate any suggestions. And I’m talking a very small area. Call it 10 yards wide or so and maybe extending 10 feet into the pond.
