The dam wave hole is awesome at high water. It looks small, yet sticky and sort of scary as it has some characteristics of a low-head dam. But the hole is pretty flushy just about everywhere but a few spots where it is real juicy; allowing loops cartwheels faltspins etc.

Heres a quick vid of the rapids at 11,000-12,000cfs.

This wave forms around 11,500 -12,000cfs. River right, no eddy. Big and juicy!

Matthew Cooper here. I rode my bike here yesterday and played all night and morning. At around 11,400 - 12500 cfs there is only one surfable wave/hole on rivber right that is medium-large and deep, no eddy though. However, i finally gathered the courage to play in the dam hole and it was incredible at 12,500. Putting in is tricky cause you have to carry over a wall, but the dam hole allows all sorts of moves at high water, loops, spins blunts, cartwheels. And though the dam hole looks a bit scary and sticky, its really not, as the water washes down stream into the rapids below. I took some cell phone pics and video and will try to upload soon.
Oh yeah, the eddy is piroutt-tastic too.

Yep.. You can throw ends. and then get washed out, while still throwing ends, winding up squirting and spinning into an encouraging eddy.
Its just like big water! HA!
And into the eddy line we dance!
