Blue River Report
4-14-2025
Flows and water temp remain steady, as is the fishing, which has been excellent. With the angling pressure, expect fish to be picky at times, but that's nothing unusual for the Blue. Fish will be in a variety of water types, from holes to pocket water so it pays to make a couple of casts in multiple water types. Hatches have been primarily midges.

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.
