Great pictures. Really neat to follow the process. I'm with Carolyn in using a liner and vacuuming without totally emptying the pond. We are having a redo this spring, so I will be attempting to catch all the fish and putting them in well oxygenated and filtered containers for a day or so while they redo about 60% of the walls. then I can refill and get my fish back in. they can finish the rest of the ground work then. Will still freak out the fish having the guys working around them but I don't have anything large enough to hold them for more than a few days.
