Plain-language explanation
Teton River near St. Anthony is flowing at 432 cubic feet per second (cfs) as of Oct 25, 11:15 AM PDT. That is on the low side for this time of year: lower than about 81% of the daily flows this gauge has recorded for this date (give or take 7 days) over 106 years of record (1890–2026).
The middle half of those historical flows runs from 449 to 592 cfs, with a median of 508 cfs; the lowest 10% of days are at or below 398 cfs and the highest 10% at or above 670 cfs.
Over the last 24 hours the flow has been steady (-4.8%). In the last 7 days it ranged from 377 to 454 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).
