Flows and water temps remain steady, and the fishing continues to be good. The weather is looking excellent all week, with temps expected to be mid to upper 40's, with a couple of shots of snow starting midweek. The Blue continues to be a good spot to get a break in from the slopes. As per susal, most fish will be in/near wintering holes, and the you can expect ice below Silverthorne. Hatches have been primarily midges.

About Blue River Fly Fishing

For Denver area flyfishers, the Blue River, which rests just an hour-and-a-half west of the city off I-70, is an excellent after-work and short weekend option. However, due to its location, it can suffer from crowding.

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.
