I agree with what anthropic said.
Just a couple days ago I watched 1" to 1.5" long BG swim up a 6" vertical drop of half inch deep water to escape my main pond and swim upstream to my forage pond. A whole school of them would just keep trying and I would see one make it every twenty or thirty seconds. Can't imagine how many made it in 24 hours.
Tiny fish can move in water a person would think is way too shallow for them to swim in. If there are any other BOW's around a big rain event can move fish.
I saw a green heron once pick up a fish out of my main pond, I spooked it, and it flew and dropped the fish in flight. It dropped the fish in the same pond but another 30 feet and it would have dropped it in my sediment pond. So I think birds can move live fish at least short distances because I have seen it happen.
You do not want GSF get established early. They will readily eat most of your fingerlings you stock if the GSF get to about 5 or 6 inches. Don't ask me how I know.
