Count, my experiences on Buzzard, FWIW.
Sucked @ 550 on lower Plateau (@Cameo) gauge. Was really fun at 1,100 on Plateau @ Cameo gauge, but you have to be really careful on the blind corners because the eddies are micro and things are moving quickly. A rough comparison would be Bear Cr. @ 300, but without the bedrock riverbed -- just boulder gardens on Buzzard.
A second run would have been really fun when you know where the problems are, but we were out of time. If you go, take some flagging and mark any strainers for the next crew down. The one strainer I remember -- I'm sure is still there because it was about 3 feet in diameter with a full radius of branches just above the water line.
I came around an s-curve and there was this nasty, nasty strainer about 50 feet in front of me and the only brakes were sliding into a half-boat eddy and quickly grabbing tight for willows.
I'd do it again in a heartbeat if it was over 800, just exercise good boat scouting practices on the first run through.
What are those other creeks that steven mentions like? Same kind of thing: royal flush?
