There is a large strainer (big tree branch), that is hard to see form O hole, but it very prominent when you paddle a ways down from it. It would be sketchy if you had to swim. It starts river left and makes its way to nearly the middle of the river. I haven't been up today, but it was there at about 7/8 last night.
