Plain-language explanation
North Umpqua River at Winchester is flowing at 684 cubic feet per second (cfs) as of Oct 24, 2:30 AM PDT. That is among the lowest flows on record for this time of year: lower than about 99% of the daily flows this gauge has recorded for this date (give or take 7 days) over 84 years of record (1908–2026).
The middle half of those historical flows runs from 926 to 1,565 cfs, with a median of 1,120 cfs; the lowest 10% of days are at or below 810 cfs and the highest 10% at or above 2,420 cfs.
Over the last 24 hours the flow has been steady (-4.1%). In the last 7 days it ranged from 684 to 783 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.
