Current River Flow Updates

Latest update: 1/13/2022 --

Winter conditions on the Blue. Silverthorne has been a great option lately- there is always open water and fish to be had despite surrounding frigid temperatures. You are also in close proximity to some good eats, so if you can't handle the cold head in for a warm lunch. There isn't much fishable water north of town anymore because the river is now frozen, but the stretch through the outlet mall and just below the dam remains wide open. Sight fishing small nymph rigs have been a go-to for us. We have been fishing 7.5 foot fluorocarbon leaders down to 5X with a single size BB shot. Any of the small nymphs in sizes #16-22 mentioned below are a good starting point!

Historical River Flow

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 are abound here and the fish are typically very aesthetically 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 aesthetically Mysis Shrimp should be your focus. Small streamers can also be protein-rich during the low light hours. This river is fishable year round and sees no shortage of anglers.
