Reading time: Oct 24, 3:10 AM PDT · Provisional data
Flow is in a typical range for the date. Rivers are generally easiest to fish and float when they are near their normal flow, but this status says nothing about water clarity, hatches, hazards such as wood in the river, or dam releases.

Plain-language explanation
Rogue River at Grants Pass is flowing at 1,180 cubic feet per second (cfs) as of Oct 24, 3:10 AM PDT. That is on the low side for this time of year: lower than about 84% of the daily flows this gauge has recorded for this date (give or take 7 days) over 88 years of record (1939–2026).
The middle half of those historical flows runs from 1,260 to 1,660 cfs, with a median of 1,450 cfs; the lowest 10% of days are at or below 1,140 cfs and the highest 10% at or above 2,040 cfs.
Over the last 24 hours the flow has been steady (+1.7%). In the last 7 days it ranged from 1,110 to 1,180 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 within the range this gauge normally sees at this time of year (or the deviation is too small in absolute terms to matter).
