John Day, N. Fork

River flooded at 28K cfs at the Monument Gauge on May 14-15, 2010. Had not flooded this high since 1997 (30K). Only other flood of this magnitude was in 1925. Due to flooding BLM river ranger/Grant County Sheriff did not recommend running river weekend of May 21-22, we did it anyway. Flows were approx 8.75 @ put-in and 8.5 at take-out. (Middle Fork was contributing 2K of this amount). 1 14' raft and 1 16' cataraft and 1 tandem canoe, mixed levels of experience among the boaters. No new debris encountered (somewhat surprisingly).
Campsites and their access were reasonable. No problems. Shuttle driver reported that a couple of fellas floated river at peak flow. I assume there were no problems for them. River appears runnable (and importantly, camp-able) at flows up to 15K or less. Open-canoeists can expect to regularly take-on water unless they sneak rapids.
