Randell you can expect the run at Watertown to be friggin huge right now.
I am not sure what to expect at these levels but can tell you there are Class 5 situations at all water levels on this part of the Black. I would think some are washed out but you can be certain that many things like Glens Falls, The Rocket Ride (Low Head Dam) and Poop Chute get down right freaky at these levels.
Also the whole run except Hole Brothers and Knife Edge are in a gorge that is very tight for big water. Similar in size to the Elora Gorge. The walls are layer upon layer of cracks and crevices.
I would suggest that if your determined to run this section you might want to hook up with some locals who are intimate with the Black Gorge.
