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.

Blue River is still in winter mode, however the fishing has still been productive. The fish are generally holding in the deeper slow water and right along the bottom water column. If your passing a nice shelf or run adjacent to a pool don’t hesitate to get a few good drifts through it. Get your flies down to the fish’s level as they wont move much for a small fly. As far as hot flies go think mysis or egg up top trailed by a small (20-24) midge/bwo on 6 or 7x fluorocarbon tippet.

Go to patterns: bts mysis/charlies mysis (16-20), UV emergers (20-24), black beauty (22-24), desert storm midge (20-24), poison tung (20-22), trout beads/otter eggs, juju baetis (20-22).

Using the listed flies or similar should put fish in the net. Focus on your presentation as well as your depth. If your not bumping bottom occasionally get deeper. Use long leaders with a white or clear indicator as these fish are indicator shy, especially with the low gin clear flows. If you see that indicator do any sort of movement set that hook, many times in the winter the strikes are very subtle.
