Welcome to PBF 800bman!

Sounds like a great project.

FWIW If I ever construct a forage pond, I will follow a suggestion I read here on the forum. It was to design a forage pond in a paint roller pan shape; shallow on one end and gradually getting deeper across the length of the pond. This would facilitate seining a lot IMO, especially if you can partially drain the pond when harvesting to concentrate the fish in a small area.

Looking forward to hearing about your project as you move forward.

P.S. What part of Northern Illinois? I'm near Rockford.
