Colorado River Winter Trout Update - Nymphs Shine, Flows Skinny, But Limits Possible

Colorado River Colorado Fishing Report Today

About
Hey folks, this is **Artificial Lure** comin' at ya with your Colorado River fishin' report for January 12th, 2026, right here in the heart of Colorado. Winter's grip is tight on the upper stretches, but that don't mean the trout ain't bitin' if you know where to look.

Weather's chillin' us out today—high around 32°F, lows dippin' to 15°F under partly cloudy skies with light winds from the northwest at 5-10 mph. No tides up here in the Rockies, but flows on nearby tailwaters like South Boulder Creek are runnin' skinny at 9 CFS below Gross Reservoir per Rocky Mountain Anglers' latest report from yesterday, makin' for technical fishin'. Sunrise at 7:22 AM, sunset 5:07 PM—plenty of daylight to chase 'em.

Fish activity's solid for winter trout: browns, rainbows, and some brookies holdin' deep in boulder pools and tailouts. Recent reports from Rocky Mountain Anglers show good numbers on midges and tiny baetis, with limits possible on warmer afternoons. Anglers pulled strings of 12-18 inch rainbows and wary browns last week at 80 CFS flows earlier, droppin' now but still fishable.

**Best lures and baits?** Go nymphs heavy: small zebra midges #18-22, RS-2 #18-22, blue poison tungs #18-20, San Juan worms #14-18, or jig leeches for searchin'. Drop a pheasant tail or juju baetis off the point. Streamers like wooly buggers or thin mints in black/olive shine in bigger pools. Live bait? Worms or small minnows under a float for panfish and trout. Fly guys, rig a sprite midge or sprout midge dry if ya see risers.

Hot spots: Hit the tailwater below Gross Dam on South Boulder Creek at Walker Ranch—solitude, educated wild browns in the canyon. Or try Williams Creek Reservoir nearby for stocked rainbows and brookies on bait or flies.

Bundle up, fish slow and deep, and respect the regs—trout limit's usually 4 fish over 16 inches on these waters.
