went and looked today while my daughter was with family in the area. there is certainly a surfable wave right where the directions said it would be. flows are about 18,800. Looked like good eddy service and a smooth wave not epic but solid, wide and well shaped.
I did not want to get in alone and test it out. There is a basalt ledge that extended and indeterminate distance that I did not want ot windowshade on and end up unconcious.
After tkaing out it may be a 50yd carry back to the truck. total park and play. On the other side of the river there may be more/another feature that comes in at a higher level but I couldn't figure out how to get there quickly. It was too far to really tell how good it was on the other side.
