Blue River Report
8-3-2026
Flows are still at 53.9, which you've probably guessed already. Early AM the water temps in Silverthorne will start in the lower 40's, and reach the mid 40's before sunset. Closer to Green Mountain, temps will be noticably warmer, but the Troutlets can be a great place to spend a entire day with goood water temps all day. These locations have been getting harder to find as of recent. Otherwise, sight fishing still remains the best tactic to target larger fish, but try to be stealthy as the fish can get pretty spooky with the fishing pressure and the flows. Go more finess and tactical. Hatches have been primarily Midges, Caddis and BWOs.

About Blue River Fly Fishing
Despite its location and a good population of trout, not many people consider the Blue their favorite river. However, for those who know the Blue, “Big trout,” “Broken tippet” and “the one that came off,” are all phrases that are commonly heard as those anglers head home from the river.
It hasn’t always been that way; improvements on the Blue over the last four or five years have benefited the fishery. New catch-and-release regulations to strengthen the population of larger fish and the fact that the rainbows, browns, and brookies in this river have bellied up to a diet of seafood – a white shrimp called Mysis – have played a big part in these improvements.
The Blue below Dillon Reservoir is not a typical Colorado tailwater. In fact, fishing the Blue below Dillon is a somewhat urban experience – it flows through Silverthorne, and those fast food joints, gas stations, and factory outlet stores make a strange setting for a gold medal trout stream.
