John, they're in there but as you noted very hard to catch. Fishing was great 40 years ago, and went downhill gradually for crappie. However, about 5 years ago it picked back up considerably. Sutton has never had much of a creel limit though, and I saw people take 200 fish out of there at once.
Since the plant converted to gas, it's changed the characteristics some. I'm pretty sure a few were caught in that 3rd lake back in the winter.
