Buzzard's kind of a pile, IMO.
We ran it last year and were a little disappointed. It's not that it couldn't be good, but it would take some cleaning and then a lot of water (>1000 on Plateau) to get good. I want to say that the Plateau gauge was about 600 when we did it (mid-April) and it was super boney. It got upto like 2,000 for a while last year and that would of been rad. Lot's of little feeder streams between Buzzard and the Plateau gauge.
It's a class IV run, but with enough juice to make it fun the hazards would come up on you pretty fast. You should take this weekend to go clean it! Just take wire cutters instead of chainsaws. All the fences are probably seasonal and you might just be able to detach them and set them aside without even hurting anything.
If you have ethical issues with that, think about what 2,000 cfs and floating wood must have done to those fences last year anyway. Flood, barbwire, and wood, it would be like storming the beachs at Normandy except you're there voluntarily???
