Is there a way to put a six inch pipe from the forage pond to the main pond and by opening the valve drain the forage and the water into the main pond? This would be easier than seining and is what I am considering.
Absolutely! You want to make sure the pond bottom slopes toward the drain though. I would even go a step farther. I would put in a hole at the deep end to scoop out the fish that don't go out the drain.
