Current River Conditions

The Middle Colorado River near Glenwood Springs is in prime condition for fall fishing, with consistent flows around 1,900 CFS and clear water clarity, making it a great time for targeting large brown and rainbow trout. Cooler temperatures have encouraged steady trout feeding patterns throughout the day, with the most action occurring from late morning into early afternoon. Browns, especially, are preparing for the spawn, so anglers are likely to encounter aggressive fish in deeper runs and pools.

Best Flies and Patterns

  • Nymphs: Effective patterns include Prince Nymphs and Pheasant Tails (#14-18), as well as RS2s and JuJu Baetis (#18-22), which mimic the Blue Wing Olive nymphs trout are feeding on.
  • Streamers: This section is ideal for streamers like Autumn Splendor and Conehead Zonkers in black or olive, as trout aggressively chase baitfish patterns. These work best in deeper runs and along drop-offs.
  • Dries: While dry fly action is limited, Parachute Adams and BWOs (#18-22) can bring results during overcast afternoons or slower flows in the early morning.

Conditions Summary

  • Flow Rate: 1,900 CFS
  • Water Temperature: Cool, stable for fall trout activity
  • Clarity: Clear
  • Best Times: Late morning to early afternoon for peak feeding

This stretch near Glenwood Springs offers a mix of wade and drift fishing opportunities, with excellent access points like Grizzly Creek and Two Rivers Park.
