The year on this river
In a typical year at the Columbia gauge, the Duck 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 2,160 CFS; the September median is 213 CFS.

Common questions
When is the Duck River usually at its fullest?
At the Columbia gauge, the fullest stretch of a typical year is Jan–Mar, with the single highest monthly median in January (about 2,160 CFS). The leanest months are usually Aug–Oct.
What is a typical summer flow on the Duck River?
The July median at this gauge is about 333 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 Duck 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 50 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.
