Snakebite IMHO, the paint roller type is more drought friendly. I've drained that pond, and seen old CNBG beds as deep as 6', and this year's (with all the rain we had this spring) less than a 1" from the surface. I may be overthinking it, but I want the fish to select their own spawning location, and not have the pond dictate it.
If a constant source of water was available, the flat bottom would sure work nice though.
Good thread.
