Don't believe anything Tomcat says. He's too old, from a flat state, and has forgotten how to paddle by now, for sure.... j/k
Good to hear from you old man!
#1) Rock garden, or hole
garden at this years flows, start center and dodge at will, but don't avoid EVERY hole, or it's just class II.
#1.5) Big munchy hole that you can avoid by going right, or fight to stay center for big fun.
#2) it's a left curving rapid, I usually start center and end center.
#3) quick and short, three big holes in the center are good to go if you have a good boof stroke, or easy to miss by staying to the right side.
#4) Longer than the others. Start center. Just before the rapid curves to the left there will be a big "superman" wave right of center. Yep, there's a hole behind it so make your kayak fly! Don't worry, it will flush you no problem. You can cut left for a less-steep line at the curve, or hesitate, stay right and bust left just before the diversion on the right for a steeper drop into the last part of the rapid.
#4 1/2) (above bridge) boat scout, keep your head up, rock garden stlye boating with a few ugly holes, but a bunch of surf play.
#5) Directly after the bridge, the water calms. Eddy out left as the river curves about 90-degrees right. Looking down stream you see a rock near to the right bank, then a second rock about 10 out. Between the two is the green-water tongue that you want to ride down. Keep in mind that at high water the rocks are under water and appear as raised mounds of water and your line is the "saddle" between. AFter you punch the minor hole below the tongue, the rapid quickly curves left about 90-degrees. Follow the center of the river through the curve. A good start at the top of this rapid is key to a good finish.
#6)On the approach, it looks alot like #2 with it's left curve, only the river is a bit wider. It runs the same, but is longer, curves back toward the right at the end and is shallower on the right side, so I usually stay center or left of center a tad.
#7)Read and run fun, multiple lines.
I lived is Buena Vista for a couple years and ran the Numbers 3-4 times a week, but that was about 5 years ago and now I only make it up there 2-3 times a year, so if my recollection is hazy or just plain wrong, then blame it on the beer I've drunk since then.
edit: ---Oh, these are from a kayak point of view, your rafting milage may vary.
