Commissioner,
Go to this site for a list of commercial fish suppliers in Indiana.
http://www.in.gov/dnr/fishwild/fish/fishing/commfish.htm There are a few suppliers in southern Ohio you may be close to also. Let me know if of none of the preceding pan out. I would wait until water cools off for stocking. But suppliers that do not keep fish in holding tanks will not seine until the water cools off anyway.
Since you are in southern Indiana and your email has rangebombs, do you have anything to do with the area where the ANG drops bombs for practice? I used to load those bombs on F-4's for the 122nd CAMS ANG in Ft. Wayne Indiana.
