Plain-language explanation
Middle Fork Willamette River near Dexter is flowing at 1,250 cubic feet per second (cfs) as of Oct 24, 3:10 AM PDT. That is among the lowest flows on record for this time of year: lower than about 91% of the daily flows this gauge has recorded for this date (give or take 7 days) over 81 years of record (1946–2026).
The middle half of those historical flows runs from 1,610 to 3,575 cfs, with a median of 2,500 cfs; the lowest 10% of days are at or below 1,260 cfs and the highest 10% at or above 4,020 cfs.
Over the last 24 hours the flow has been steady (+0.0%). In the last 7 days it ranged from 1,230 to 1,250 cfs.
Regulated flow: upstream dams or diversions influence this gauge, so the “normal range” above reflects managed flows and can differ from natural river behavior.
Why this status: Flow is at or below the seasonal 10th percentile and in the lower 40% of all days on record.
