The year on this river

In a typical year at the Horseshoe Bend gauge, the Payette River runs fullest Apr–Jun and leanest Oct–Dec. 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 June days at this gauge ran above 7,205 CFS; the October median is 1,000 CFS.

Common questions

When is the Payette River usually at its fullest?

At the Horseshoe Bend gauge, the fullest stretch of a typical year is Apr–Jun, with the single highest monthly median in June (about 7,205 CFS). The leanest months are usually Oct–Dec.

What is a typical summer flow on the Payette River?

Is the Payette 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 116 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.
