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.

The Blue River is absolutely humming through Silverthorne, but the fishing was very good.  Big fish like big water!  Wading is a bit of a challenge and landing some of these fish in the strong current is tough, but as long as you are careful when wading, you should do great.  Nymph fishing is best.  Work the edges, seams, and soft water.  Also work the fast stuff with a lot of weight.

Go to bugs for me where charlies mysis and bts mysis, pats rubber legs, Egan’s Frenchie, Two Bit Hooker (red), and Red Squirmies.  Either tight lining or fishing under and indicator will produce.  When working up the bank, make sure you look for fish in close.  I spooked several monsters that were no more than 2 inches off the bank.

Good luck.
