The year on this river

In a typical year at the Gasquet gauge, the Smith River runs fullest Jan–Mar 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 January days at this gauge ran above 5,000 CFS; the September median is 258 CFS.

Record context

This gauge has measured daily flow since 1932 — 94 years of record. The largest daily average ever logged here was 180,000 CFS, in December 1965. Rivers do that sometimes; it's why the safety panel above isn't decoration.

Common questions

When is the Smith River usually at its fullest?

At the Gasquet gauge, the fullest stretch of a typical year is Jan–Mar, with the single highest monthly median in January (about 5,000 CFS). The leanest months are usually Aug–Oct.

What is a typical summer flow on the Smith River?

The July median at this gauge is about 473 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 Smith 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 94 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 11532500 (SMITH R NR CRESCENT CITY CA), chosen because it best represents the Gasquet and the Forks of the Smith down to Jedediah Smith Redwoods. Daily records here reach back to 1932.
