Plain-language explanation
Madison River near Cameron is flowing at 994 cubic feet per second (cfs) as of Oct 24, 2:15 PM PDT. That is on the low side for this time of year: lower than about 80% of the daily flows this gauge has recorded for this date (give or take 7 days) over 28 years of record (1951–2026).
The middle half of those historical flows runs from 1,020 to 2,000 cfs, with a median of 1,180 cfs; the lowest 10% of days are at or below 906 cfs and the highest 10% at or above 2,420 cfs.
Over the last 24 hours the flow has been steady (+0.0%). In the last 7 days it ranged from 915 to 1,040 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).
