Blue River - above Green Mountain Reservoir Fly Fishing Report
Update 9/22/18--Enjoy scenic fall fishing conditions along the length of the Blue River above Green Mtn. Res. Colorful cottonwoods and aspen trees will have you forgetting why you are even there. Once you come to your senses rig a hopper dropper and drift it tight to the banks to get that dropper to swing under to the hiding trout. Hippie stompers, Amy's ants and Chubbies are still guides choice up top. Hot Belly PT's purple, Hare coppers green and Radiation beatis will be your choice for dropper flies. Move around to locate where fish are holding. Bank to bank shallow water is not ideal holding water so keep moving until you find better pocket water with structure and deeper pools. With these cold night temps, make sure you keep an eye on REDDs and leave them alone to do what nature intended the trout to do. On that note, throw some streamers, good patterns are Peanut Envy's Black Or White, Flashy Sculpzillas, Galloups Sex Dungeon Blk/Red and Yellow Home invaders all will turn heads. Vary your retrieve but a fast aggressive retrieve will get some solid results. PS-try a small black leech pattern sub surface.

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.
Winter/Spring: Midges, Baetis
Summer: Mayflies, Midges, Stoneflies, Caddis, Terrestrials, Small Streamers
Fall: Midges, Baetis, some Caddis, Small Streamers
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.
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.
