I would like to stock LMB, CC, and FHM. I already have some BG and GSF. The spillway drains into a 6' by 6' pool that is about 6' deep. From there the water flows down a creek. So if I were to stock adult fish the only fish that would go through would be the fingerlings and fry right? Before we drained our pond, I was always able to take a fishing net and scoop out fish that went through.
