I live near lake Sullivan and the bass fishing in it has never been better. Millions of gizzards all over it, millions of crappie too. This year the bluegill were even big. Sullivan has been putting out great weights, and you can catch 20 lbs practice fishing when there aren't 100 boats out there.
These lakes I mentioned are also very small compared to lakes like Patoka, and not even a cove on lakes like KY. Their ecosystems are extremely fragile and easily influenced, and they are getting along fine with Gizzards. IF you want great sized bluegill, then no, they probably are not the best for the lake, but that's about it. There are TONS of little crappie in Patoka, which are just fine as a food source to bass, as well as the many little bluegill etc. Each year those shad spawn it gives millions if not billions of tiny little fishys for the bass to eat. And being that Indiana isn't an all year growing season for fish, it takes several years for a Gizzard to get to the size that not many fish will eat it. There is always a class of gizzard shad that bass can feed on.
I don't know what Patoka's problem is, I think a lot of it is pressure. There are a TON of good sized bass in there but they are hard to catch, and no, the small fish do not seem to be very numerous.
