Colorado River trout settle into fall rhythm as flows hold steady

What's next

Expect temperatures to keep easing gradually over the next several days as nights cool further into October, which is the normal direction for this time of year on the Colorado River system. With the upper gauge holding a steady 7,470 cfs rather than spiking, wading and drift conditions should stay consistent heading into the weekend, making the dawn and dusk windows worth planning around as daylight continues to shorten.

This week's new moon means darker nights, which tends to push low-light activity earlier into the evening and later into the morning on cooler-water trout fisheries generally. The main variable to watch is any scheduled change to the dam release below gauge 09380000, since a jump off the current baseline would shift conditions more than the gradual seasonal cooling will on its own.

Context

Mid-October marks the seasonal turn from summer patterns into the more stable, cooler-water fishing that typically carries the Colorado and Salt River systems through fall and into winter. A steady dam release paired with a consistent temperature reading across gauge sites is typical for this point in the calendar rather than unusual, and nothing in the current readings suggests this season is running early or late.
