Blue River Fly Fishing Report- April 17, 2021-Vail/Beaver Creek/Silverthorne CO

Wade & Walk Fly Fishing Trips


Fishing Report For: April 17, 2021

Excellent conditions Below Dillon Res.

The Blue River has three distinct sections that are very different from each other.  The upper section begins on top of Hoosier pass and winds its way through Breckenridge into the Dillon reservoir.  this upper section is a freestone fishery with smaller browns and rainbows that are easily caught on dry flies.

The Middle Blue River runs from below Dillon reservoir to Green Mountain reservoir.  This section is probably the most popular because of it’s very easy access (including behind the Silverthorne Outlet stores). This section of the blue below Dillon is a Tail water fishery that sees a lot of fishing pressure throughout the Year.  Midges, Mysis shrimp and annelids are the predominant food source for these rather large and elusive Trout.

Better fishing down stream of Silverthorne along HWY 9 headed towards Kremmling.  There are numerous DOW access points along the stretch headed to Green Mountain.  The Lower river begins below Green Mountain reservoir and confluences with the Colorado river 15 miles downstream, this lower section is best known for its “Jurassic Park” section that is only accessible by raft and a competent oarsman.  There is wading access just below the Green Mountain dam.

4/17/2021- This is one of Colorado’s best tailwater fisheries. The Blue below Dillon Res. is running at 55 CFS which makes for some great sight fishing around and down steam of Silverthorne.  More of a traditional Trout stream the more you go north from the outlet stores. The Blue is a world class Trout river.  Below Green Mountain is also at about 133 CFS. Both flows are lower the the annual average’s, this has the Trout podded up in the deeper slower holes. We ar guiding the Blue on Full days only as the drive will make it worth while. Jurassic Park is NOT floatable.

Recommended Patterns: Barr Emerger BWO #18-22, Black Beauty #20-24, Black Brook Sprout Midge size 20-22 Tung BH Zebra Midge red, purple and black #18-24, Mysis Shrimp size 16-20. Eggs, RS-2 Black and Grey #18-24 Squirminators #12
