Blue River - below Green Mountain Reservoir Fly Fishing Report

Last Update 07/30/2016 - If I could pick one place to go spend an afternoon tossing some dry flies this week, this would be the place. There is a less-than-common hatch of very small pale yellow colored Craneflies mixed in with a handful of green drakes that has the fish feeding heavier than I have ever witnessed in many years of fishing this stretch. Dry dropper rigs with a PMD dry (same size and color as the craneflies) and larger drakes have been the ticket. If you decide to float this stretch, throw the same dries as well as larger nymph rigs and big streamers.

River Information

This stretch of the Blue River, below Green Mountain River, offers limited public access and is largely privately owned. The first three miles below the dam can be quite productive, however somewhat difficult to fish depending on flows. Too high and wading becomes nearly impossible. Too low late in the summer, and the river can become overgrown with moss and seemingly unfishable. Fishing will be best between 150-300 CFS. The river sees abundant bug life and offers, for  the most part, year round fishing.

Seasonal Conditions

The Blue River below Green Mountain Reservoir is fishable year round. Winter and early spring time will be primarily a nymphing game with fish focusing in on midges, baetis and egg patterns. Summer offers anglers the opportunity to match the hatch with the various caddis, mayflies, stoneflies and terrestrials this canyon sees. Covering water with a dry/dropper combo would be a good bet. With fall comes a noticable refocus on midges and mayflies and the stoneflies and caddis begin to taper off. Streamers can produce throughout the majority of the year as well.  


River Access

Access here is very limited due to the majority of this 25 mile piece of water being privately owned. The first three miles below Green Mountain Reservoir are the most popular and public parking access exists just below the dam. Anglers should take caution when fishing here in adverse conditions or if you are not in good physical condition. There is a very steep incline that must be descended and ascended from the parking lot. This can be quite difficult/dangerous when covered in snow and ice.
