Wind River and North Platte flows ease into fall trout window

What's next

Flows should keep easing over the next several days as irrigation demand tapers for the season, the normal pattern on both drainages this time of year. Clear skies around this week's full moon typically mean colder overnight lows, which should nudge water temperatures down another degree or two by the weekend and sharpen daytime feeding windows as the water cools through the 60s.

The low-flow stretch near gauge 06258000 should stay easy to wade with good clarity at 26.7 cfs. The higher-volume water by gauge 06236100, still pushing 542 cfs at 66°F, has enough current to support solid morning and evening drift windows before temperatures drop further into next month.

With a bright full moon overhead, expect feeding to shift earlier into low light — dawn and dusk are the windows worth building a weekend trip around.

Context

Late September marks the start of the fall transition for Wyoming's freestone and tailwater fisheries, as the warm-water afternoon lull of summer gives way to steadier feeding as temperatures ease through the 60s toward the 50s. Flows recorded here are well off summer peak, consistent with reservoir releases and irrigation draw tapering for the season. Nothing in this week's readings suggests an early or delayed transition — the drainage is running on a normal fall schedule.
