Green River Fly Fishing Report

April 9th, 2021

The nymph fishing on the Green River has been very good.!  Zebra Midges, Grey Soft Hackles, Black Beauties and RS2s will all produce.  The flows remain low, averaging 850cfs and will likely remain at this low level for the rest of the month.  The Blue Wing Olives are out but not in mass quantities yet.  Look for the hatch to take off in the next week or so.  Once the BWO hatch gets going the dry fly fishing will pick up - especially on wet or cloudy days. 

Current snow-pack for the Green River is at about 80% of normal.  As of now, we are looking at a low water year.  Hopefully we get a wet Spring!  

Green River Flow Forecast  Steady Low Flows


Current Flow Level - 850 cfs


Red Creek:  Clear - subject to daily change


A Section:  The nymph fishing has been solid with size #16-18 midge and BWO patterns.  5X tippet and a quick hook set will produce lots of action.  Midges are hatching around 10am, BWO's in the afternoons.  

B Section:  The nymph fishing on upper B is really good.  The fish tend to be podded up in the middle and tail outs of the runs.  Streamers or dry dropper have been good on lower B.   

C Section:  Dry dropper rigs will produce action on sunny days.  Streamers have been good on cloudy or wet days.  The BWO hatch is better on the A and B Sections.

Hatches: Midges, the BWO's are ramping up!
