Thank you guys for the help. I agree with you Jim. I think its a water oak.

After looking at the leaves more carefully and considering the size of the tree in the picture, I think it is more likely a water oak than a blackjack.

I should have said that the leaves of the white oak subfamily have “rounded” edges, whereas red oaks usually have sharp corners or sharp points somewhere. Even the red oaks’ leaves have smooth edges, except at the location of the sharp corners or points.

Agreeing with Jim. Not a post oak but the trunk and wood color still have me scratching and figuring.

Oaks of the white oak subfamily (white oak, post oak, overcup oak, chestnut oak, chinquapin oak, et al.) always have leaves with smooth edges – no points. Some of the red oak family have fairly smooth edges, but most have clearly sharp points somewhere on the leaf. There are a great many species of oak, especially the red family, and natural hybrids, which are sometimes very difficult to tell apart. Try USDA plants database for lots of pictures.

Not a post oak. I think it’s a blackjack oak. Although I have seen water oak (which have highly variable leaves) that closely resemble these, also.
