I & some friends have run this stretch several times. Right below the Columbia Canal diversion
dam (which has been run many times on RR side--NOT recommended at very low or very high spillover
levels), there's a river-wide shoals that contains some good play waves at favorable levels, then a
stretch of flat water to the U.S. 176 bridge. Right at the bridge there's a river-wide "ledge", of
sorts, that was formed by rubble & debris dropped into the river when the bridge was widened
from 2 to 4 lanes. It's runnable, but watch for sharp rocks & rebar at low levels. After this
the next feature is Earlewood Shoals, a class 1 rock garden where the river constricts but there
isn't much gradient. After this, the next rapid starts at the approach to I-126 bridge, where
several good surf waves form at the right water levels--class 2 at low flows & class 3 at
higher flows. At the pool below this drop is the Saluda confluence on far river right, but the
river is a half mile wide at this point. Staying left, the next rapid is Water Works (class 2+), a
boulder garden with a few feet of gradient. The final rapid before the take-out at Gervais Street
bridge is the class 2 Jailhouse Shoals, so named for the former state penitentiary that was located
here. Overall, it's a good beginner- to intermediate-level run at moderate flows; a more serious
run at higher flows. Edit
