i have a question regarding the best way to structure the partition between an upper waterfall pool and the main pond as shown in my awesome picture.
my pool on the left is roughly 15" deep, and i'm using stacked chilton cut strip stone (~3" thick, 4-6" wide, 8-12" long) to build the wall between that pool and the main pond (represented by the dark gray blocks). my coping shelf between the two is angled slightly back in retaining wall fashion so the center of gravity of the wall will be leaning back toward the pool slightly.
i have seen designs where people just go straight up, without backfill, and run the liner of the small pool directly up the wall. for some reason this seems less than ideal. i think i would rather backfill with dirt as shown in the picture to provide more support for the wall, and put the liner over that. does this make sense? can i get away with doing this without a concrete footing for the retaining wall?
