Green River Fly Fishing Report
April 11th, 2024
Currently, the flows on the Green River are in the ideal range most of the day, 1,800cfs with a huge bump to 4,000cfs from 6:00pm till 1:00am daily. Flows are averaging 2,000cfs. This is ideal for the hatches as the aquatic insects thrive in the oxygenated water.
The Blue Wing Olive hatch has started and should ramp up over the next couple weeks! The BWO's on the Green River are grey in color and most are a size #16-18. They will get a little smaller as the hatch progresses into May. The hatch is weather dependent and can start as early as 11am or as late as 2pm. Sun is your friend as it warms up the water. Once river temps come up you will want cloudy or wet weather to trigger the best hatches. Nymphing at about 9-10 feet deep has been very productive, with solid dry fly action later in the day. The fish will move into shallower water when the Baetis hatch starts.
The midge hatch is also going strong in the mornings, allowing for solid subsurface fishing as well. On calm mornings you can find pods of fish up in the tailouts, bubble lines, and back eddies
Snow pack for the Green River is at about 110% of normal in the Green River Drainage. Flaming Gorge Reservoir is at about 83% capacity. We are looking great for Spring and Summer flow levels!

Fluctuating Flows
A Section: The entire A Section is fishing great! The Midge hatch begins in the mornings around 10am, with the nymphs being active earlier in the morning. On calm days there are pods of trout up on these tiny bugs - especially in the scum lines. The fish get much more active when the BWO's start to emerge and tend to do most of their daily feeding in a 4 hour window. They will also move into shallower and faster water to chase the grey morsels.
B Section: Nymph rigs, dry-dropper and streamers have all been producing on the B Section. Commit to streamers, or dry dropper rigs on lower B.
C Section: The action has been good on streamers. There are also some BWO"s coming off, but not as thick as the upper stretches of the river. Red Creek can blow out anytime in the Spring, be ready to change fishing plans after hot or wet days.
