Blue River - at Silverthorne Fly Fishing Report

Last update 07/016/16 - Flows below the dam are low once again and the fishing has been pretty solid. Standard tailwater nymphing methods with small midges, smaller caddis pupa, drake nymphs, and baetis has been productive. In the afternoons, make sure to keep the caddis box close. The hatches this year have been nothing short of epic! We also have been having some luck fishing dry dropper rigs with Chubby Chernobyls trailed with any of the aformentioned nymphs. If you want to mix it up a bit, cover water using light colored streamers on sunny days. The Sunrise Sculpzilla and the Tan Home Invader have pulled more than a few nice fish for me up on the Blue the past few years.

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.

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.
