Spring Fly Fishing on Utah's Green River

The Spring is arguably the very best time of year to fly fish the Green River in Utah.  The warmer water being released from Flaming Gorge Dam greatly increases the trouts' metabolism and initiates the most consistent aquatic insect hatch of the year, the Blue Wing Olives.  The BWO's begin making an appearance in March and last well into late May.  The peak hatches usually occur mid to late April during inclement weather.  

May offers amazing opportunities to hit the first terrestrial dry fly fishing of the year.  Cicadas show up almost every year in early May, with some years their presence being the trouts main focus  The window before high water offers amazing fly fishing and sees little river traffic.  We are only given 3 days notice as to when high water will begin, the anticipated flow levels and predicted duration.  This is a great time for a last minute trip.    

March

As the temperatures rise, the fly fishing in early spring really picks up. The trout are eager to eat the larger BWO mayfly nymphs. March provides very solid nymph fishing.  Dry fly opportunities on midges are abundant as well.  The Streamer fishing on the lower sections of the river is excellent and is some of the most consistent of the year.

April

The Green River fishes as well as any other river in the lower 48 states in April. Being a tailwater fishery, we do not get the muddy snow runoff which so many other rivers are susceptible to. Whatever your preferred method of fly fishing may be, April on the Green River provides some of the best fly fishing anywhere. Incredible hatches, high catch rates, and the ability to stalk individual rising fish are just part of what make fly fishing Utah's Green River in April special.

May

The Green River fishes excellent in May before and after high water. High water typically begins around May 20th and last 2 weeks. However, every season is different due to weather and snowpack. Some of the largest trout are caught during high water as all trout in the Green are displaced by the high flows. Being a tailwater fishery, the Green clears up relatively fast and good fishing usually resumes 2 days after the first day of high flows. Blue wing olives, trout eagerly awaiting terrestrial insects, large trout chasing streamers, and a chance at hitting the cicada hatch are all a part of the Green River in May.

Hatches:

 

Blue Wing Olive (BWO"s) #16-18

Midges size #20-24

Black Stoneflies #14

Terrestrial Insects - grasshoppers, ants, cicadas, crickets, & beetles #8-16

 

Best Techniques:

 

Dry Fly:  Fish to rising pods of trout during the morning midge hatch.  Look for hundreds of trout rising during a blanket BWO Hatch which occur on cloudy days around 1pm.  The first Terrestrial dry fly fishing of the season also starts when temperatures start creeping into the mid 70's.

 

Nymph: deep runs & pools (7-10 feet deep)- The trout will move into shallow water and over moss beds mid day when the BWO nymphs begin to emerge

 

Streamers: fish slowly - in the Spring they fish best in the pool tailouts and on the lower sections of the river.
