Today's 245 cfs is 36% below the median for this date — which counts as low water here.

We don't have launch notes for this one

This page is built from the USGS gauge at this location, so the flow and weather are real — but 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.
