We don't have launch notes for this one
This page is built from the USGS gauge at this location, and uses available public readings. We haven't verified where to put in, what the hazards are, or whether this stretch is legal or sensible to paddle. We'd rather say that than invent it. The links below are where to find out.
We also don't have a verified safe-flow range here, so the Paddle Score reflects weather only. Judge the flow number against local knowledge, not against our score.
Do your own homework
We show you live conditions. For local knowledge — where to put in, what the hazards are, whether it's worth the drive — here's where paddlers actually talk about this water. We don't vet these sources; check the dates and judge for yourself.
