Too low for reasonable whitewater. (May be paddled as a scenic float trip, but all gradient will be a scrape or carry.)
Passing just to the left of the 1st haystack, a boat will deflect towards the rock wall. I have not yet seen anyone hit the wall but it will come by fast and very close. Passing on the right of the 1st haystack increases the odds of tip-over (experienced paddler or not) because of the height of rise to the standing wave and the depth of the hole just to the right of it (see photo).
