As JHAP said, numerous 2-3 pound bass on average is not pie in the sky... Having a couple trophy bass, say 8 lbs or larger isn't unreasonable either. However, if you are shooting for a world record, you will have to forget about numerous 2-3 pound bass and focus more on smaller numbers of larger bass. 3 acres is a a fair amount of water to work with though...
I wouldn't worry about the turtles.
