Colorado River Fishing Report: Hot Water Conditions Mean It’s Time to Give Trout a Break

If you're planning to fish the Colorado River near Glenwood Springs, it's time to rethink your plans.

Why We're Pulling Off the Colorado River

With overnight air temperatures staying above 65°F, the river isn't getting the chance to cool down. As water temperatures climb, dissolved oxygen levels drop — making it much harder for trout to recover after being caught and released. Fishing warm water puts unnecessary stress on fish and can lead to post-release mortality even when fish appear to swim away healthy.

Where to Fish Instead

Because of these conditions, we're no longer floating the Colorado River until temperatures improve. Instead, we'll be focusing on cooler water found in the upper freestone streams and tailwaters — including the Frying Pan River, where trout have a much better chance of thriving. The Frying Pan consistently runs cooler through summer and offers excellent dry fly and nymph fishing even during the hottest weeks.

Tips If You're Heading Out

If you do plan to fish this week, keep these guidelines in mind:

  • Bring a stream thermometer — stop fishing if water temps exceed 67°F
  • Fish early morning when temperatures are at their lowest
  • Use barbless hooks and minimize fight and handling time
  • Consider giving the Colorado a break until mid-August

A short pause in pressure can make a big difference in protecting this incredible fishery for the months ahead.
