I'm wondering how you would go about relocating fish from a pond
that is being removed or replaced? Is there anybody you could call who
would help you strain them out and relocate them to a new home? And how
would you go about it? I imagine you would drain the pond within a few
inches and then just strain them into a container? What would you do?
Have you ever thought about this?

you have the right idea about draining the pond down - use some of that
water to fill whatever containers you are going to use to transport them.
Try to do it as gently as possible, not "chasing " them any more than you
have to - less stress on the fish. A local pet shop might be interested in
them, although this is the "off-season" for most places to be stocking up on
fish
Good Luck Gale :~)
