Glenwood play park, 15500 to 17000 cfs.
The wave was preaty fantastic on Sunday. At 15500 the river left wave had a stable foam pile and was not terribly steep, it made for some great surf, clean 360's, and bouncing blunts we to be had. The river came up by the end of the day (16500 ~ 17000) and the wave started to go through a cycle: green out, curl up, crash on your bow, give up good surf. It got to be preaty iffy towards the end of the day, you either lucked out and got a good spot in the cycle, your you got a lot of water closing out on your head.
I moved over to river right towards the end of the day when there was the higer flows. It's steeper, has more foam pile, and a bit of a shoulder. It looks more intimidating but you get used to it preaty fast. It's definatly good to go at all levels mentioned. Don't know what the right side is like at the 15500 level, the left side was great for so long I just stayed over there most of the day.
Big thanks to the designers of this park. I'll be doing all my boating here until the wave is gone. Its the best surf I"ve had since vacationing to Montreal.
