I think that could have a strong correlation. I guess you would have to get out average temp charts and lat/long lines and other things to really compare growing seasons.

But I know there is a move to higher than the conventional 10:1 BG:bass ratio of old. especially if you want big bass. More like 30 or 50:1. And more mouths to feed usually equals smaller average size fish. more small fish more for the bass to eat?

Also I have never fished a lake for bass, so I don't know much about bass/BG ecosystem in a lake

Get out and fish.
