Plain-language explanation
Salmon River at Salmon is flowing at 1,320 cubic feet per second (cfs) as of Oct 24, 1:45 PM PDT. That is in the normal range for this time of year: higher than about 56% of the daily flows this gauge has recorded for this date (give or take 7 days) over 112 years of record (1912–2026).

Over the last 24 hours the flow has been steady (+8.2%). In the last 7 days it ranged from 1,060 to 1,340 cfs.
Why this status: Flow is within the range this gauge normally sees at this time of year (or the deviation is too small in absolute terms to matter).
