The Blue River is flowing its normal historic level through the winter months. Angler can find reliable fishing between Town Hall and the base of Dillon Dam. Dillon Reservoir is 87% full so outflows should stay consistent throughout the winter.  It’s hard to go wrong with an egg-midge combo right now.

Seasonal Hatches and Tips

Fishing the Blue River in Colorado during winter demands precise presentations and a selection of flies that match the prevalent insect activity. Here are some effective patterns:
Midges: Essential in winter fishing. Use patterns like Zebra Midges, Mercury Midges, RS2s (Rim's Semblance 2), and Disco Midges in sizes ranging from #18 to #24.
Blue-Winged Olives (BWOs): These may hatch sporadically. Carry patterns like Parachute Adams, Sparkle Duns, or Pheasant Tails in sizes #18 to #22 to imitate BWOs.
Egg Patterns: Trout might focus on drifting eggs. Carrying egg patterns in various colors (#12 to #18) can be productive.
Streamers: Occasionally, larger fish might respond to streamers, especially if fished slowly and with a natural movement. Woolly Buggers, leech patterns, or articulated streamers in natural colors can work well.

Adaptation and observation are crucial. Pay attention to the water conditions, fish behavior, and any signs of insect activity. Adjust your presentation techniques, depth, and retrieve rates accordingly.

About the Blue River

The Blue certainly is a beautiful as they come, and gives visiting anglers a real sense of Colorado. It’s a tough river at times, but a good challenge will always make you a better fly-fisherman. The water is extremely cold coming off the bottom of Lake Dillon. This cold water dictates and controls the feeding window of the trout. It’s not a great morning fishery, but as the water gradually warms up throughout the day, the fishing improves dramatically. The upper stretches of the Blue (from the base of the dam through Silverthorne) holds trophy trout, fattening up on Mysis Shrimp from the lake above. The water is gin clear requiring perfect presentations. Down stream the river changes back in a typical mountain trout stream with a diverse insect life. Several tributaries inter the river before it spills into Green Mountain Reservoir.
