Where to Go Arkansas River – Pueblo

Open 9 am to 6 pm Daily

Report Date: 10/31/2026 - HAPPY HALLOWEEN!

Current Conditions:

Flows below Pueblo Reservoir are stabilizing following recent seasonal volume adjustments, settling into a fishable range around 360 to 380 CFS. Water clarity continues to improve daily after recent rain and lake turnover, currently offering roughly 18 inches to 2 feet of visibility. Subsurface water temperatures remain remarkably stable due to the massive thermal capacity of the dam, keeping trout active and evenly distributed throughout the entire tailwater corridor from the dam down toward Interstate 25. Fish are holding in classic tailwater water, including slower inside turns, gravel bars, and deep trough seams.

Fishing in the AM ok. We caught fish on Jedi Baetis and worms. Good on RS2's in the PM.

Weather:

Short Term -

The near-term weather pattern brings classic late-autumn conditions, starting with crisp, cool mornings in the lower 40s before ambient temperatures quickly climb under bright afternoon sun. Light to moderate valley breezes (around 8 to 14 mph) frequently ripple across the broader tailouts. This afternoon surface chop is a major advantage for anglers, as it helps break up high-visibility windows and effortlessly conceals terminal tackle and indicators in shallower runs. Because the reservoir buffers the river against sharp air temperature drops, feeding windows remain open consistently across the day without typical morning lock-jaws.

Long Term -

Looking ahead through the rest of the shoulder season, the lower Arkansas basin will experience standard late-fall meteorological shifts characterized by multi-day warm spells alternating with fast-moving cold fronts. While daytime highs will continue to provide comfortable, sunlit windows for fishing, overnight lows will regularly dip well below freezing. This gradual seasonal cooling will slowly pull down overall water temperatures, compressing the most active feeding cycles into a concentrated late-morning to mid-afternoon timeframe.

Hatches:

Heavy summer bug activity has fully given way to the dependable late-fall lineup of midges and Blue-Winged Olives (BWOs). Subsurface midge larvae, pupae, and emerging baetis nymphs dominate the daily drift, providing a steady food supply for resident trout. While overcast or low-wind afternoons can still spark occasional localized BWO surface activity along quiet bank eddies, the vast majority of trout feeding behavior remains heavily focused on opportunistic subsurface foraging.

Tactics:

With flows sitting in the upper 300 CFS range, anglers should rig with enough split shot or heavy tungsten beads to ensure flies punch quickly through the fast upper column into the slow boundary layer along the riverbed. Because trout are hugging soft, grassy margins and inside seams to escape the pushy current, technical dead-drifting along tight bank lines produces the most consistent strikes. Utilizing an adjustable indicator system allows you to easily lengthen your leader and shift depth as you transition from deeper trough seams into shallow, sunlit tailouts.

Tips:

Always thoroughly fish the close-in bank water before wading out into the river, as stepping in too quickly will spook trout holding along the soft edges. Capitalize on afternoon wind gusts that chop up the water surface, using the broken light to scale up leader strength without alarming fish in clear glides. Finally, pay close attention to shallow gravel bars during late-fall trips, staying mindful of staging brown trout and taking care to avoid stepping on or disturbing active spawning redds.
