I have a 30 acre pond behind me that outlets into a creek. Thus far we have caught Carp and bullheads. Not sure, aside from minnows and turtles, if anything else is in there. The question, on a 30 acre, 6 - 10 foot deep (mostly 6 feet), spring fed, but slightly muddy pond in Minnesota, what else is likely to survive or take?

Oh, and for those that remember, I finally put some new photos up:
