Blue River - at Silverthorne Fly Fishing Report

Last Update: 3/29/16- Its no surprise that the Blue River in Silverthorne continues see it’s fair share of crowds regardless of the day of the week, time, or fresh snow reported at the resorts. Fishing the Blue in Silverthorne has been overall good to very good with plenty of fish still willing to take a variety of well presented flies! Nymphing with the standard tailwater patterns (including mysis, midges, and baetis) give anglers the best chance to turn some noses. Some of our favorite patterns include: Epoxy Mysis, Jujubee Midges, RS2’s, Rainbow Warriors, and Zebra Midges.

River Information

The Blue River through Silverthorne offers anglers the opportunity to catch a 20" trout in the morning and then shop at the Gap in the afternoon. While it may seem strange to park in an outlet mall's parking lot and get wadered up next to a family looking for some afternoon shopping, the fish that reside here can quickly refocus that distraction. This stretch of river sees considerable pressure, however the fish typically respond favorably to a good dead drift. Sight fishing opportunities abound here and the fish are typically very aestheically pleasing in coloration and size due to the protein rich diet provided by the dam of Dillon Reservoir.


Winter/Spring: Midges, Baetis, Shrimp

Summer: Mayflies, Caddis, Shrimp

Fall: Baetis, Shrimp 

Seasonal Conditions

In true tailwater fashion, the flies you need to catch fish here are typically the same year round. Nymphing will be the rule throughout the majority of the year, however some good summer dry fly fishing can exist given the right conditions. Midges, Baetis, Caddis and the ever popular Mysis Shrimp should be your focus. Small streamers can also be effective during the low light hours. This river is fishable year round and sees no shortage of anglers.
