Sandy
3. Marmot Dam site to Revenue Bridge(Sandy Gorge)
May 1, 2026
Rating table updated--CFS reading at Marmot corrected
| Reporter | Teresa Gryder |
| Gauge Reading | 859 cfs at SANDY RIVER NEAR MARMOT, OR |
| Flow | Low Flow |
On April 29 the USGS finally applied the shifted rating table to the Marmot gauge, and the foot to CFS conversion is closer to what we knew pre-Dec25-flood. On the USGS page the shift was applied retroactively, so there's no visible jump, but on the AW gauge page the jump is visible, from 1300 to 875 CFS.
We ran the Gorge on May Day. The log jam was still passable on either side (we ran left), and you can scout from either side but most folks portage right.
At Boulder drop the RIGHT line is 100% clogged, no go, *death on a stick*. The old center left line is no good at this flow either because the new rock diverts 70% of the flow into the cave/sieve under the house sized boulder in the middle of the river. We snuck far left under the cliff. At this flow hardshells get stuck in the first pinch but monkey their way through, then the rest is boatable. The sneak feeds directly into a sieve and you must hit a tight eddy R to avoid it, then meander through a rocky eddy until you can peel out to run the bottom ledge, which is junkier than it used to be.
(The featured photo of Boulder drop with the blue wavesport kayak shows the right line without wood and the center left line without the new rock: pretty picture but not current.)
Rasp rock was GTG down the right.
Drainhole still has a large log stuffed in Door#2 with its root ball in the current. Swimming there might well be the end of you. We all ran the 'sneak' by driving Right off the main flow and into the shallows. Scout left, portage right.
At Revenue we ran the top 'bar fight' section in the center right slot, there's a new hole in there. You head toward the wall then break left and pick a side of the sharp rock to go on. It's manky and dangerous, but we all made it right side up. This top section is not visible from either shore: scouting doesn't help unless you have a drone. The portage is on the left. The bottom part has a clean line down the R edge, scout left.
