I fish places ranging from 20-1600 acres that all have fish over 8lbs. I prefer to fish the smaller >100 acre spots because they usually don't have boat ramp access and thus don't get tournament pressure. As far as I'm concerned there are things more important than lake geography in determining trophy potential.
Forage is one thing I look at. I tend to catch bigger fish on lakes with gizzard shad or stocked trout. In fact all of the fish over 8lbs I have seen or heard of being caught came from lakes with one or both of those forage fish. Another thing to consider is competing species. I prefer to avoid lakes with too many competing predator species like walleye, pike, striped bass, etc.
Fishbrain is a good resource. I despise that app but it is useful for looking at the leaderboards to see if any big fish have been caught in the past. There are places that go under the radar but for the most part this is a pretty quick way to determine if a lake can produce a trophy fish, especially places that don't keep records.
Once you have narrowed down some places pay close attention to the fish you are catching. My pb would have been a 6lb fish on another lake. On that same lake I caught a 19" fish that weighed 5.5lbs. A fish needs good growing conditions to reach maximum size. Once you have determined a good lake just grind at that lake exclusively. Bite windows are small so the more often you are on that lake the better your odds. Some of the lakes with trophy potential have sucky overall fishing.
