All up, through 2400 it stays class III with no major moves and low consequences of swimming.
Would love to hear a trip report from anyone, probably won't get there personally. You should post one for posterity here since it will likely not see these levels again in our lifetime.
Trip Report: OK, since no one else seems to want to, here's a report on Lower Blue at high water @3300.
First off, based on swim consequences I would say that the area between the Wall and the first diversion dam is IV-, however skills needed are still only III. There are few major moves, only avoid a couple of small but powerful holes below the wall, but a swim will last until the river right eddy above the second diversion or the stick pile below the next river bend below that. The rest remains class III- to III.
The main attractions are the ledge wave and the wave inside Wall rapid. The ledge wave has perfect eddy service, time enough to miss your roll once and still make it. The wave itself is over head height, steep shoulders, and a nice pocket, good to go for spins, cartwheels, blunts and the occasional flushing loop. Really fun spot, was told another group spent 3hrs on this wave alone.
The wave in the wall is tall, fast, and surge-y, tough to catch but fun and wild if you get it. Many won't even attempt to land it. Start at the micro eddy at the upstream edge of the cliff face and back into the curler hard river left to catch it.
The rest of the run is washed out and basically sit and stare for any competent boater.
Overall good but not great, 3 stars. Still its probably the most fun you an have in a playboat in Summit county at these flows.
