Where to Go Arkansas River – Pueblo

Open 9 am to 6 pm Daily

Report Date: 11/5/2026

Current Conditions:

Releases below Pueblo Reservoir have spiked up to a heavy 830 CFS—a dramatic surge from the previous 380CFS that we saw leading into Halloween weekend. This surge in volume has completely redistributed fish positioning throughout the tailwater corridor. Trout have backed off main-channel runs and fast center chutes, moving up in the water column and packing tightly into soft bank margins, inside seams, slow-velocity eddies, and behind submerged boulder structure. While wading options are now limited to soft edges, the increased flow dislodges massive amounts of food from the substrate and provides fish with generous overhead depth cover, making them significantly less line-shy than during low-water flows.

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

Weather:

Short Term -

High-plains autumn weather over the next 3 days will bring pleasant conditions, with daytime highs reaching the low-to-mid 60s under partly cloudy skies. Crisper morning starts in the low-to-mid 40s warm rapidly by late morning. Afternoon valley breezes building to 8 to 15 mph will create a steady chop across broad tailout glides, further helping to mask heavy leader profiles and stout nymph rigs.

Long Term -

Extended 10-day regional forecasts point to a stable fall cooling trend across the eastern plains. Highs will gradually step down into the upper 50s, with overnight lows hovering near 35°F. The massive thermal capacity of Pueblo Reservoir keeps subsurface water temperatures remarkably steady, buffering the river against sharp ambient air drops and keeping feeding windows wide open across the entire day.

Hatches:

Heavy summer bug activity has fully given way to the dependable late-fall lineup of midges and Blue-Winged Olives (BWOs). Heavy 830 cfs currents disperse surface hatch concentrations, but midges (#20–#24) continue hatching continuously throughout the day. With higher flows scouring the stream bed, bright red midge larvae, bloodworms, and dislodged pupae have become the primary subsurface target. Overcast afternoons can still prompt localized Baetis (BWO) activity along quiet, recessed bank eddies, though trout feeding has shifted almost entirely to subsurface foraging.

Tactics:

Heavy, fast-moving water requires stout terminal tackle and heavy-duty nymphing rigs. Upsize your fluorocarbon tippet to 3X or 4X to withstand abrasion along submerged riprap, logs, and boulder margins. Ditch light micro-weights and add substantial split shot (BB to 3/16 oz) or heavy tungsten bead flies to cut through the pushy upper water column and deliver your flies straight down into the slower boundary layer along the bottom. Concentrate all dead-drifts along soft shoreline margins, inside turns, and tight current seams where fast water meets slow eddies.

Tips:

Anchor multi-fly nymph rigs with large, high-attraction lead flies—such as San Juan Worms, hot-wire egg patterns, crane fly larvae, or large scuds—to grab immediate attention in murky bank slots. Trail these with bright Red Zebra Midges, Tubing Midges, or dark Baetis nymphs positioned inches above the stream bed. Step back from the bank and work close-in edge drifts before stepping into the water, as non-spawning fish will frequently be tucked within just a few feet of the shorelines.
