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

Flow: 98 cfs Silverthorne

Clarity: Excellent

Water Temperature: Low to mid 40’s

Hatches: Midges and blue-winged olives

14 Day Forecast:  Look for low flows and technical fishing. Anglers can expect to see sporadic hatches of midges and the occasional blue-winged olives

Tips and Other Information:  Considering the time of year, conditions are ideal in the town of Silverthorne, and fishing has been good. Anglers can expect to see sporadic hatches of midges and blue-winged olives with the occasional riser in the slower pools and tailouts.  In addition to the trout eating midge larva and pupa; Mysis Shrimp imitations are fooling a decent number of fish.  A red larvae or a Mysis pattern trailed with darker pupa has been an effective rig as of late. Its hard to go wrong with a small Parachute Adams to fool the trout feeding on adult midges or blue-winged olives.
 
Effective Patterns:    #20-22 Mercury Flashback Pheasant Tail, #20 Laney’s Mysis, #20 Jujabaetis, #22 Stalcup’s Baetis, #20 Mercury Flashback Pheasant Tail, #22-24 Mercury Black Beauty, #22 Red Midge Larva, #20-24 Brassie, #22-24 WD 40, #18 Hot Tail Flash Egg, #24-26 Parachute Adams, and #22 Matt’s Midge

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 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.

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.
