Blue River - above Green Mountain Reservoir Fly Fishing Report

River Information

While still a tailwater by definition, fishing above Green Mountain Reservoir will mimick a freestone in many ways. Bug life is abundant here and the river is home to many different size classes of trout from small to very large. Rainbow and Brown trout swim in these waters and can offer anglers a little more elbow room in comparison to their outlet mall counterparts several miles upriver. This can be a very hatch oriented stretch of river, but when it's "on", it can be "on" in a very big way. This is a very scenic stretch of river anglers would be best served to cover water throughout the day in search of active fish. 

Recommended Flies

Winter/Spring: Midges, Baetis

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

Fall: Midges, Baetis, some Caddis, Small Streamers

Seasonal Conditions

This stretch of river is fishable year round. Winter will typically be a nymphing game with small midges, baetis and egg patterns being the go-to patterns. Summer time can bring about some fantastic hatches, including the ever popular Green Drakes, and dry fly fishing can get quite good at times. While not as plentiful as other rivers in the state, stoneflies do exist in this river and will catch fish. Fall can still provide dry fly fishing Baetis action, however nymphing will be a more consistent way to put fish in the net. Kokanee Salmon also make a run out of Green Mountain Reservoir into the river during the Fall. 

River Access

Headed north out of Silverthorne, the river parallels Hwy 9 for the most part. Access is plentiful throughout and is clearly marked. Some of the places worth checking out are the McDolad Flats Campground, Davis Springs Campground, Heeney Bridge, and Columbine Landing Access. The Blue River State Wildlife Area also offers over 3 miles of public water. There are several private stretches throughout this portion of the river so please be respectful of these boundaries.
