Blue River - below Green Mountain Reservoir Fly Fishing Report

Last Update: 3/15/15-The Blue below Green Mountain is fishing pretty well. Kyle from the shop recently headed there and found success using an egg, baetis and nymph patterns in the deeper holes. The midday hours were most productive when the sun was at it's highest. The trail is still a little icy in spots so use caution wading. For the most part though, this river should fish well until runoff kicks in and wading becomes difficult.

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. 


Winter/Spring: Midges, Baetis

Summer: Mayflies, Caddis, Stoneflies, Terrestrials, Streamers, Midges

Fall: Midges, Baetis, some Caddis Streamers

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.
