|Big water flush. Gauge (303 sq.mi. drainage) is midway on reach, thus very accurately portrays actual flow.|
The flat shelved rock (for which the river is named) creates hydraulic jumps that are a blast. At
the lower discharges it should afford many surfing opportunities. At the larger levels, a thrill
but probably not technically challenging.
One report forwarded to AW includes descriptions of being in troughs that "I could not see out of and at least one haystack that I avoided that was probably 7-8 feet tall."
Benjamin Swain provides (2008-04-07):
We put in at the Hidden Paradise campground just outside St Paul, rather than the old 421 bridge. A fun beginner river, some good surfing waves.
