Not official but I know sometime Quercus palustris, Pin Oak is called Swamp Oak and Quercus rubra, Red Oak prefers well drained soils.

So I assume Pin Oak is more tolerant of excessive water.

You all have received tons of rain this spring. Perhaps someone will have a picture of an over watered Red Oak.

We have the same thing around my house. We received over a foot and a half of rain in a week and a half. Now redbuds, dogwoods, white and red oaks (I've observed around 10 species around here), yellowood, maples (silver, red, and sugar), sycamore and finally cottonwood all have black and/or yellow/brown on the leaves killing some leaves outright. Now that the rain has stopped and it has been near 90 the last two days, the damage seems to have come to a stop. Perfect conditions for fungus to attack wet and cool but not cold or hot when the spotting began. Trees are used to this especially if it is isolated and short in duration. If your trees are otherwise healthy, they should re leaf.

Of course pics will help the experts ID the pest and it might be worse that I mentioned. Have you noticed any other trees doing this in your neighborhood.

I think toro is onto it. Excessive rainfall --> waterlogged soil, with oxygen depletion to the roots, etc.
I've been noticing black, curling margins on leaves on some of the oaks in my yard - and these are the ones on relatively 'high ground'.
I have a nice, 15-yr old yellowwood tree, in a lower-lying spot - that's still wet/boggy from all the rain we had over the past two weeks or so - that leafed out normally but the leaves are now wilted and yellow. I think the 18+" of rain we got in the month of April - and well over half of it in the last week of the month - caused waterlogging of the soil. I just hope this tree can recover.
