Anthropic, I agree with your assessment that larger fish retreat deep in the summer months. I hope to make habitat structures to sink in deeper water this winter for sure. I tried using weighted wacky rigs and senkos on some 60 foot drop-offs but struggled to get them past he 1 pound bass near the top.

And interesting take on the lower fertility of clear water. That's what I thought too, but the state biologist said the opposite. He said that the clear water allows deeper sunlight penetration and therefore more water with habitat and oxygen. It will be fun to determine it's fertility over the years.

I think the larger issue here is that this is a big lake with a lot of water. It is cost prohibitive to any major fix by myself without breaking the bank. I love all your input either way.
