Gehajake, just going to have to give it a try. A lot of our public lakes have flooded tree lines that are pretty deep and they tend to be good fishing spots so I'm not sure why it wouldn't work. Just so were clear though, I'm not planning on any of this cover being that deep, it will all be at the top closer to the surface of the water.

Unfortunately I don't have any means to keep this lake full other than rain, so the as the water level rises and falls my trees will be exposed to air. So what I'm learning from this is to probably prioritize cedar trees for this middle section as it will be the hardest to replace when the trees rot away. Use maybe my elm trees and readily assessable stuff near the shore that can be much easier to replace in the future.
