Blue River Silverthorne

Fishing Report

UPDATED: 8/26/25

The "tailwater" section of Blue River through Silverthorne fishes fairly consistently year round. The fish here are technical and sometimes pickier than you would expect. Water temps normally stay within the lower forties (fahrenheit), which doesn’t produce a large variety of hatches. For the most part, small midge larva, and Mysis Shrimp (small clear/white shrimp inhabiting Dillon Reservoir), are staples of the trouts diet. Things start to get more interesting if Dillon Reservoir reaches capacity and “spills” through the top release of the dam, instead of the bottom. This causes a larger variety of aquatic insects that live in the Blue River to become active, and therefore more available to trout.

The best technique is usually nymphing under a small, inconspicuous indicator. Adjust your weight and indicator depth depending on the depth of the piece of water you are working, and to the depth at which the fish are holding. Seeing rising fish is a possibility, as is seeing some action on streamers.

Guide Tip of the Week:

The Blue River in Silverthorne is fishing about average right now. We have had some great dry fly fishing with small mayfly and caddis patterns on cloudier days. Sight fishing with nymphs and dries are best method to put fish in the net. Continue to use light tippet and small flies for these technical tailwater trout.
