Just a thought. I wonder how well it would work, if instead of using the rake, you were to take a 10’ to 20’ length of heavy chain and stretch it out along the shoreline, tie a long length of rope to each end, and then simultaneously tow both ends of the rope around each side of the pond, dragging the chain across the bottom. If it were to hang up, you could reverse direction, or simply release the rope on one side of the pond and pull the chain out of the water from the other side.
I seem to recall someone on the forum trying something similar, but I don’t remember what the results were.
