Blue River

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 blue ribbon trout stream.

Fishing Report Date: 08-19-2015

Spent an evening wading the lower blue from about 3:30-7:30. Flows are ideal or wading right now, with just about the entire river accessible. There is a ton of bug activity this time of year, with everything from big caddis, green drakes, and PMDs to small Crane flies. While the drake dry fly actions seems to have fallen off, the fish now seem to be looking for the PMDs. Just about any PMD dry fly skittered across the surface when the fish are looking up seems to get aggressive and fun takes. When the fish aren’t actively feeding up top, give a size 18 frenchie or Hanners Green Drake jig a try in tail outs and plunge pools.
