I'm also from Illinois. With a 150 gallon tank you have lots of options. Most large US fishes aren't suitable for the home aquaria due to aggression rather than size. Bass for instance simply are a mean fish that tend not to tolerate other fishes in the tank. You could keep a nice group of the more peaceful sunfishes along with madtoms, darters and topminnows. If a predatory tank is more your style, you could have a nice group of pickerel along with bullhead and maybe a group of OSS.
If you want an active tank I would advise the first example. You'll be very happy with the constant activity of the combination. I forgot to mention that you could also keep quite a few native minnows as dithers for that tank as well.
I would stay away from ponds as they tend to have very little diversity and often stocked fish (hybrids). Natural streams will give you the best range of fish and the most fun IMO.
