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:

The fishing on the blue has been fair to good as of recent. Nymphing typical tail water flies is going to be the way to go for the rest of fall and winter. Mysis Shrimp such as the BTS mysis, midge larvae, and midge emerger patterns in sizes 18-22  are among the best producing nymphs. Try a pink rubber worm or a Chamois worm in tan or cream. Followed by either an egg or mysis pattern, followed by some sort of midge larvae or emerger patter. A size 20-22 Black Beauty or WD-40 is a good choice for this river. 6x fluorocarbon is your going to be the most productive tippet size at these flows.
