Red and Missouri Rivers hold steady as early fall sets in

What's next

Expect water temps to keep sliding gradually as nights lengthen into late September; a drop of a few degrees over the next week wouldn't be unusual for this stretch. Flows at all three gauges are stable rather than spiking or dropping, so wading and bank access should stay consistent through the weekend. The First Quarter moon puts moderate solunar activity into play for early morning and early evening outings rather than a single dominant peak period.

With no storm-driven flow changes showing in the gauge data, this is a good window to plan around dawn and dusk, since these are inland freshwater reaches without tidal influence. If flows hold in this range through the week, expect the current moderate conditions to persist rather than shift sharply in either direction.

Context

Mid-to-upper 60s water temps in late September are on schedule for Red and Missouri River tributaries, which typically hold onto summer-warmed water into early fall before dropping into the 50s by mid-October. This period generally marks the shift from full summer patterns toward the more concentrated feeding windows that come with cooling water, though the current readings still sit closer to summer-transition than true fall cold-water conditions.
