Quercus, We Barely Knew Thee

We woke up this morning to a driveway full of oak leaves (from our Northern Red Oak Quercus rubrum), many of which looked like the photo above. The tree is centered in a 8'x8' patch of grass in the between the street, two driveways and the sidewalk, so I suspect it might have something to do with lack of water. But the blotching on the leaves makes me fear worse. Can anyone identify this?
