I enhanced a MODIS image taken on Aug, 31st. There is a large black body in the water that looks like an oil spill.

The image is here.

Hmmm... I'm not sure that's oil.

Could it be freshwater runoff from the floods?

I'm no expert on sat images, but that looks WAY larger than anything anyone is talking about.

I'm not sure too, it looks a little bit too large (the image resolution is 250m).
