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: Excellent

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

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.
