Green River tailwater flows hold steady into fall cooldown

What's next

Expect the dam release to stay in this steady range through the week. Flaming Gorge is a bottom-release reservoir, so large flow swings this time of year are unusual barring a change in dam operations. Water temps should keep easing lower as nights cool and the reservoir starts to turn over, which typically tightens feeding windows around low light and produces a more predictable, technical bite close to the dam.

With the moon waxing toward full, look for stronger low-light activity around dawn and dusk this week and into the weekend as illumination builds. The first real cold snap will accelerate the cooling trend fastest on the Jensen stretch, where the extra few degrees of buffer above the dam readings will close off quicker than right at the tailwater itself.

Context

Late September marks the start of prime fall tailwater season on the Green River below Flaming Gorge. Stable, cold, dam-controlled flows paired with dropping air temps typically produce some of the most consistent technical fishing of the year on this stretch, in contrast to freestone rivers that are already dropping and swinging unpredictably in temperature. Current readings sit within the normal range for a dam-controlled system at this point in the season.
