Oak wilt shows up first at the top of the tree, not at the bottom of the canopy. What you are seeing is probably one of many leaf diseases. These leaf diseases are very common this year with all the rain. https://extension.umn.edu/plant-diseases/oak-wilt-minnesota https://extension.umn.edu/plant-diseases/leaf-spot-diseases-trees-and-shrubs
