SetterGuy - yes, the pond looks much better full. I have been waiting since Oct of last year for this moment and one of the reasons I bought this place was because it had rocks. Sometimes my back disagrees however.
snrub - the pallets are (were) stacked 3 high with regular bricks between each and with cinderblocks under the bottom ones on the deep side to level them somewhat. Who knows what's going on now. I'll have to wait for the water to clear up and take a boat ride to investigate. Hopefully I do not have a bunch pallets on the very bottom! Ponds are fun aren't they?
