Pat Dorsey’s Stream Report: Colorado River

Fishing the Colorado River should be on everyone’s bucket list. Whether you’re a walk/wade fisherman or prefer float-fishing, this river has it all!

Current Conditions:

Clarity: Good

14 Day Forecast: Look for hatches of midges, blue-winged olives, and Tricos.

Tips and Other Information: The Colorado River has shaped up nicely and is currently fishing well.  The leaves are peaking now, and the brown trout spawn is beginning. Anglers can expect to see a strong midge hatch in the morning, followed by Tricos, then a reliable “olive” hatch in the afternoon. In the slower pools and tailouts, the dry fly fishing has been very good.

Note:  Colorado Parks and Wildlife and Denver Water are conducting a stream restoration project on the Williams Fork River (below the reservoir to the confluence of the Colorado) that will begin on October 1, 2019 and last 4 to 6 weeks. Expect heavy equipment in the river, low flows, and muddy water for several weeks. I am told they will begin working at 7:00 a.m. each morning and continue working throughout the day, so plan accordingly. I would highly recommend another location, as the fishing will be poor with the muddy water.  This will also affect the clarity on the Colorado River for miles.  Your best bet is to fish Pumphouse or above the confluence of the Williams Fork in Lone Buck, Paul Gilbert, etc.

Pat Dorsey’s Fishing Report: Colorado River

Fishing the Colorado River should be on everyone’s bucket list. Whether you’re a walk/wade fisherman or prefer float-fishing, this river has it all!

Current Conditions:

Flows: 414 cfs Parshall and 735 near Kremmling

Clarity: Fair

Water Temperature:  Low to mid 40’s

Hatches: Midges, sporadic blue-winged olives, and a caddis or two

14 Day Forecast: Look for the onset of spring run-off.  Clarity will change based on warm weather trends. Look for hatches of midges, blue-winged olives and sporadic caddis.

Tips and Other Information: The Colorado River is fishing fair to good in the Parshall area, especially for trout in the 8-12 inch range.  The numbers have been decent, but the majority of the fish are between 8-14 inches. Anglers can expect to see sporadic hatches of midges, with the densest hatches mid day.  It’s hard to go wrong with egg-midge combos this time of year.  Some of my favorites include: Mercury Midges, Top Secrets, Black Beauties, and red Larva trailed off a Hot Tail Flash Egg. The water is off-colored, but that can become a distinct advantage at times. Don’t be afraid to throw a Pat’s Rubber Legs as your lead fly and trail some flashy midges behind it. It the clarity deteriorates, fish with Chamois Leeches, Pink San Juan Worms and other brightly-colored flies. The clarity will change based on warm weather trends.

Effective Patterns:  #18 Hot Tailflash Egg, #8 Pat’s Rubber Legs, #14 Pink Worm, #10 Chamois Leech, #18-20 Buckskin, #20-22 Sparkle Wing RS 2, #20-22 Mercury Pheasant Tail, #20-22 Mercury Midge, #22 Minute Midge, #22-24 Sparkle Dun, #24-26 Parachute Adams, and #22-24 Griffith Gnat.

Fishing Report: Colorado River

Current Conditions:

Flows: 125 cfs Parshall and 664 near Kremmling

Clarity: Good

Water Temperature:  Mid 30’s to high 30’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 this time of year.  The best fishing is between 10 a.m. and 3 p.m.

Tips and Other Information: The Colorado River is fishing quite well considering the time of year.  Anglers can expect to see sporadic hatches of midges, with the densest hatches mid day.  It’s hard to go wrong with egg-midge combos this time of year.  Some of my favorites include: Mercury Midges, Top Secrets, Black Beauties, and red Larva. Savvy anglers will find a few trout feeding on adult midges in the slower pools and tailouts. Recommended patterns include:  size 24 Matt’s Midge, Griffith Gnat, or Parachute Adams when trying to fool these surface feeders.
