Fishing Report

UPDATED: 9/28/23

Flow: 105 CFS River Graph

The "tailwater" section of Blue River through Silverthorne fishes fairly consistently year round. 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's flows are around 105 cfs. Even though the caddis hatches have mostly subsided. Caddis dries and parachute adams are a great double dry fly option right now. A nymph rig with natural imitations of small stoneflies, Mysis Shrimp, mayfly emergers and midges have been working well for us recently. Sight fishing is the name of the game here so if you don't see fish, keep moving (unless you are blind casting double dry flies looking for a riser).
