Blue River Silverthorne

Fishing Report

UPDATED: 6/23/2022

Flow: 55.7 cfsRiver 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 60 cfs which is a decent flow to fish this tailwater. CPW freshly stocked the town sections with good sized rainbow trout. Streamers can be fun to try after they stock the river, but small bugs and fine tippet will be the name of the game for the foreseeable future. We are seeing a few baetis hatching, and midges as usual. A nymph rig with small natural  imitations of Baetis and midges have been working well for us recently. Sight fishing is the name of the game here so if you dont see fish- keep moving.  A tandem dry fly rig, featuring tiny midge or Baetis imitations as the second fly can also produce a few takes when fished to trout that seem to be looking up.

Some trout have been taking advantage of the increased flow by moving into pockets closer to the banks to feed...

Mid May:

Here are the results of some sein samplings from behind our shop in the Blue.  We are seeing strong numbers of tiny golden stonefly nymphs (size 18-20), and more sparse numbers of both Baetis nymphs size 18-22, and olive midge larva size 18-22.

11/3/20: We spent a day fishing in town with Kory Lewis to see how he fishes The Blue River. Sight fishing with very light indicator rigs was the name of the game. Kory was fishing a size 18-20 non-beaded pheasant tail as an attractor fly and a #22 gray RS2 Dun as his second fly. Not much weight was needed due to low flows.

Kory Sight fished to a nice rainbow that ate the #22 gray RS2

We caught several brown trout as well. A pleasant sight to see in the Silverthorne section of The Blue. 

While sight fishing to a big rainbow, this brown decided to swoop in and eat the natural pheasant tail before the rainbow could.
