Tuolumne River A Grand Cyn of Tuolumne above Hetch Hetchy

Is this flow normal for August 1?

Today's 54 cfs is 38% below the median for this date — which counts as low water here.

The median flow on this date is 87 cfs, across 18 years of USGS record at this gauge. Whether that is runnable depends on the stretch — this is context, not a recommendation.

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.
