Pond Boss Forums POND CONSTRUCTION Creating habitat Concrete pipe

Anything that is laying on the bottom and is only a foot to 18" in height will eventually only look like a bump in the bottom of the pond as silt and sediment accumulate. I put some stuff like that spread around my pond bottom on shallower water than you and I don't think it does much good. I also cribbed up concrete foundation along with cedar trees in the middle (that go from the bottom to almost surface) and when I snorkel around these areas always see lots of small BG.

If it were me, I would stack it in piles that would go up the bank incline and reach up to within a couple feet of the surface. If aesthetics were unimportant I would go completely to the surface (but my wife did not want a trashy looking pond) but if you will have a boat out there keep it where it will not be a problem. I would pile them along an incline bank so there is everything from deep cover (for winter) all the way up to shallow cover (for summer). That way the fish have a choice to suit their needs depending on conditions. I would make 3 or more piles strategically located where I thought I would want to fish from the bank.

You likely will get catfish reproduction if you have cavities. I have stumps and concrete ledges in my pond that is three years old and in the last week have caught four 5" CC. So I know I'm getting reproduction. That is something you may or may not want.
