Blue River - Silverthorne

Difficulty Intermediate/Advanced
Ideal Days To Fish 3/8

Weekly Report

Report DateMarch 4, 2021
Fishing on the Blue has been relatively consistent over the last few days. Flows have held steady, water clarity is high and temps have been relatively mild. Sight fishing is a game changer when it comes to this tricky tailwater. Do your best to locate holding trout and work on your sight fishing game. This is one of the easier rivers to do so. Thurs (3/4) will bring winter weather and snow. So come prepared for a slow start. That said, if you can manage the elements you’re in for a productive day on the water. In the days to follow, the weather is expected to be mild making for longer days on the water. During this time, expect trout to spread out more, but favor the deep and soft water most of the day. Small and simple midge larva/pupa patterns have been garnering the best results. In the early hours, think larva, but as the day progresses, trail with an emerger. Starting on Tues (3/9), a cold front will move in so be prepared to adjust accordingly.

Detailed River Info

Background

Below Dillon Dam is a prized section of the Blue River that runs 19 miles until it meets the Green Mountain Reservoir. The stretch of river that runs through the town of Silverthorne is one of the most sought after tail waters in Colorado. Dillon Reservoir is one of the few Colorado reservoirs that was stocked with Mysis Shrimp and as a result, when water is released from the dam, shrimp trickle into the river. This calorie-rich meal is the trout equivalent to a body builders training supplement and results in some beefy fish! This section of the Blue is unique in that it runs through the tourist heavy town of Silverthorne. Therefore, if you are looking for a fishing experience full of spectators touting Tommy Hilfiger bags with a shot at landing a trophy trout, the section through Silverthorne is for you. If you are seeking more solitude and less materialism, head north down Highway 9 and pull off at one of the designated parking areas for fishing access.

Angling

The Silverthorne stretch of the Blue is a pocket water paradise. Anglers can leave their “A River Run’s Through It” casts at home and instead focus on short and tactical casts. Anglers can expect to find Rainbow, Brown and Brooke trout along this stretch with the highest concentration of trophy Rainbows being located below the dam. With the exception of Mysis Shrimp, the fly selection for the Blue is relatively consistent with the other popular Colorado tail waters. Size 18 – 24 Midge and Baetis nymphs produce year round. In the warmer months, this stretch of the Blue experiences quality Green Drake and BWO hatches. The Blue River is an accessible year round fishery and can easily be coupled with a half ski, half fish day or a family trip to the outlet malls where you drop the family and you seek much needed alone time on the water. 

River Access

The tail water section of the Blue River below Dillon Reservoir has several miles of public water access between the town of Silverthorne and Green Mountain Reservoir. The most popular section runs behind the Silverthorne Outlets and can be accessed very easily. If you're looking for more solitude, wander north on Highway 9 towards Green Mountain Reservoir. While there is sporadic stretches of private water, the public water sections can be easily identified by parking and Department of Wildlife signage.
