Blue River Silverthorne
Fishing Report
UPDATED: 11/7/24
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 and is fishing very well at the moment. CPW did a small stocking of 14-18 inch Cutbow trout. These fish can be fun to catch on small streamer patterns, and nymph rigs. Focus on nymph flies like the RS-2, Zebra Midge, and Pure Midge in sizes 18-22. A small pheasant tail or egg pattern is a great attractor fly all winter long. We still recommend sight fishing and using enough split shot to get your flies in the strike zone so you can present the flies as efficiently as possible.
