The year on this river

In a typical year at the Sandy gauge, the Sandy River runs fullest Mar–May and leanest Aug–Oct. Where today's reading falls inside that rhythm matters more than the raw number — the same flow that feels thin in spring can be the summer norm. Half of all past April days at this gauge ran above 2,850 CFS; the September median is 409 CFS.

Record context

Common questions

When is the Sandy River usually at its fullest?

At the Sandy gauge, the fullest stretch of a typical year is Mar–May, with the single highest monthly median in April (about 2,850 CFS). The leanest months are usually Aug–Oct.

What is a typical summer flow on the Sandy River?

The July median at this gauge is about 695 CFS — half of past Julys ran higher, half lower. Late summer is this river's lean season, so expect readings to drift down as the season goes on.

Is the Sandy River safe to float right now?

No flow number can answer that, and this site never labels a river safe. What the data can tell you is how today's reading compares with 81 years of this date's history — well above typical means pushier, colder, faster water. Pair that context with a PFD, a look at the river from the bank, and a call to a local outfitter before you commit.

USGS gauge 14142500 (SANDY RIVER BLW BULL RUN RIVER, NR BULL RUN, OR), chosen because it best represents the Dodge Park through Oxbow Park to Dabney. Daily records here reach back to 1911.
