Blue River - below Green Mountain Reservoir Fly Fishing Report
Last Update: 3/29/16- Approximately 45 minutes north of Silverthorne, the Blue River below Green Mountain Reservoir is another option for anglers to utilize during this part of the year (especially if you’re looking for more of a relaxed experience, as the Blue River below Dillon Reservoir tends to get crowded based on its current fishing conditions and accessibility to I-70). We recommend nymphing with smaller midge and baetis patterns (with eggs, and worms in the line up as well). Finding the deeper wintering holes with adequate amounts of weight can produce decent results. We always recommend to be cautious as you work your way down to the river access from the parking lot as it can be very slippery!

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
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.
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.
