Utah's Premier Fly Fishing Guide Service Since 1986!



Typical fly fishing conditions for the Green River below Flaming Gorge Dam in December

Average Temperatures: 25 - 48 degrees Farenheit

Fishing Scale: poor - fair - good - great - epic!

River Pressure: minimal

Hatches: Midges #18-24, some BWO's #18-22

Best Techniques:

  • Dry Fly - Look for subtle rises to locate the pods of surface feeding fish. Delicate presntations are usually needed to entice fish feeding on midges.
  • Nymphing runs & pools (about 7-9 feet deep) - The trout are schooled up in the deep runs. If you locate active fish stay there until you wear out your welcome.
  • Streamers - Fish on a slow retrive, or on a nymph rig.

  • Comments:
    December provides great midge hatches, as well as opportunities to catch late spawning brown trout. Bald eagles are frequently seen on the river this time of year. Not recommended for the cold blooded anglers.
