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

North Santiam River at Niagara is flowing at 1,240 cubic feet per second (cfs) as of Oct 24, 2:55 AM 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 99 years of record (1908–2026).

The middle half of those historical flows runs from 1,400 to 2,850 cfs, with a median of 2,240 cfs; the lowest 10% of days are at or below 680 cfs and the highest 10% at or above 3,610 cfs.

Over the last 24 hours the flow has been steady (-0.8%). In the last 7 days it ranged from 1,220 to 1,600 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).

Notes: Gauge is below dams, so flows are partly regulated. (Hand-written general note, not from USGS data.)

Data from the U.S. Geological Survey (USGS). Readings are provisional and subject to revision. Flowcast statuses are automated comparisons with each gauge's own history, not safety ratings or fishing reports. Check local conditions, weather, regulations and closures before you go. Rivers can change quickly.
