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 water continues to be high throughout the entire Blue river watershed, but if you can find wadeable water, you’ll have the river to yourself and the fish are on the feed! It seems like the bigger fish are out and about as well with the high flows.

The key is getting down. Use the heaviest weighted nymphs in your box, and then add split shot on top of that. The water is perfect for Euro-nymphing right now.


Nymphs: Jake’s DB worm, San Juan Variants, Pat’s Rubber Legs, TungStones, Jigged Hare’s Ears, Psycho Prince
