sunk 3 of these in about 4.5" of water yesterday (PVC pipe is 5'). I've got the materials to sink 9 more of these, which should do me for cover in the pond with all the other stuff we have in it.

I knew it would be, but it's funny measuring it from the water and not fishing it, but our pond is DEEP. They ended up going much closer to the bank than I had envisioned. I'm probably going to go with 1" pipe and longer sections to put the rest in 8'-10' of water.
