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: 113 cfs below Dillon Reservoir, 743 below Green Mountain Reservoir

Clarity: Good throughout it entirety

Water Temperature: Low to mid 40’s near the dam, but warms quickly as it moves down river. On the lower river the water temps are in the mid 50’s.

Hatches: Midges and blue-winged olives

14 Day Forecast:  Look for great conditions and excellent hatches of midges and blue-winged olives.

Tips and Other Information:  Dillon Reservoir is full to the brim and fishing is good throughout the river’s entirety.  In town, fish with your standard tailwater bugs, small midges and mayfly nymphs. Its hard to go wrong with Baetis nymphs this time of year. As you progress down river, stonefly nymphs, caddis larva trailed by small Baetis nymphs are effective.  Flows on the lower river are perfect right now. The lower Blue is a “nice fish” plus you can escape the crowds. The trade off is worth the compromise in my opinion.

Effective Patterns:  #10 Pats Rubber Legs,  #16 Graphic Caddis, ​ #20-22 Mercury Flashback Pheasant Tail, #20 Laney’s Mysis, #20 Jujabaetis, #22 Stalcup’s Baetis, #20 Mercury Flashback Pheasant Tail,  #22 Red Midge Larva, #20-24 Brassie, #20 WD 40, #16 Elk Hair Caddis, #14-16 Yellow Stimulator, #16 Pale Morning Dun, and #10 Amy’s Ant.

Pat Dorsey’s Fishing 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: 81 cfs Silverthorne

Clarity: Excellent

Water Temperature: Low to mid 40’s

Hatches: Midges

14 Day Forecast:  Look for low flows and technical fishing. Anglers can expect to see sporadic hatches of midges. Target the traditional winter lies (slow, deep pools) where you’ll find the largest concentration of fish.  The best fishing is between 11 a.m. and 3 p.m.

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 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 size 26 Parachute Adams to fool the trout feeding on adult midges.
