I wish I was smart enough to help ya. My thoughts just being the simple minded person I am is this. I know I know not another idea but here goes. Your 1st post says your thinking 2 ¼ arce ponds. Have ya thought about 3 smaller ponds. That would give you a whole new options. They could be connected when wanted to move from one another. Could use some kind of pipe between them with grating so that can size them. Only smaller fish could stay on one side of the pond. Or it could be closed off completely also.
