Pat Dorsey’s Stream Report: Blue River

The Blue River is a pocket water paradise. There are miles of public water between the town of Silverthorne and Green Mountain Reservoir for you to sample.

Current Conditions

Clarity: Excellent

14 Day Forecast:  Look for sporadic hatches of midges and a sporadic blue-winged olive or two. Flows are currently normal for this time of year.

Tips and Other Information: The Blue River in the town of Silverthorne is your best bet throughout the early spring months. Anglers should prepare themselves for sporadic hatches of midges and look for the occasional fish eating adults in the slower runs, deeper pools, and tailouts. Nymphing with midge larvae and pupae is your best bet right now, however.   Don’t rule out Mysis Shrimp, the trout are always looking for them. Target the transitional zones that funnel into the deeper runs and pools.  Sight fishing is a must on the Blue River as the populations of trout are way down. Straight Creek is known to add some muddy water on warm days, so don’t be surprised if the river gets off colored below the gauging station.

Effective Patterns:  ​#18-20 Mysis Shrimp, #20-22 Medallion Midge, #20-22 Mercury Midge, #22-22 Black Beauty, #20-22 Red Larva, #20-22 Manhattan Midge, #20-24 Top Secret Midge, #20 JujuBaetis, #18-22 Mercury Flashback Pheasant Tail, #22-24 Chocolate Foam Wing Emerger, #18 Hot Tail Flash Egg, #20-24 Griffith Gnat, #22-24 Matt’s Midge, #22-26 Parachute Adams.

About the Blue River

Many anglers I know have a love-hate relationship with the Blue River. Just about the time you think you have the river figured out, a humbling experience devastates your ego. The Blue River is a fantastic fishery and a favorite of mine. 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 Blue River changes back in a typical mountain trout stream with a diverse insect life. Several tributaries enter the river before it spills into Green Mountain Reservoir.

The river is  lined with cottonwood trees and willows and is tucked to the east of the beautiful Gore Range. Because the water is so cold the river fishes best from mid-day to dark. Anglers can expect to catch mostly brown trout, a hand full of cut-bows as well as a few rainbows and the river can be excellent with dry fly patterns later in the afternoons and evenings. The hatches include blue wing olives, caddis, red quills, green drakes, pmd’s, and stoneflies. The regulations are catch and release in Silverthorne and on the lower reaches the limit is two trout over 16 inches in length and is artificial flies and lures only.
