Arkansas River Fly Fishing Report
Updated 8/16/2026
Leadville to Pueblo, with live flow, weather, and closure status updated throughout the day.
CURRENT CONDITIONS
Flows have collapsed on the tailwater below Pueblo Dam, down to roughly 32 cfs, from around 250 cfs just nine days earlier, while the stretch from Leadville down through Salida is holding more typical late-summer numbers. Colorado remains in a warm, dry stretch this August, and Colorado Parks and Wildlife has a voluntary fishing closure in effect on the Arkansas below Pueblo Dam, from Pueblo Boulevard downstream to the Fountain Creek confluence, in place since August 8 until further notice. The closure applies from noon to midnight on days when water temperatures climb into the stress zone for trout. Fish this stretch at first light and plan to be off the water by 11am, and handle every fish with care.
HATCH AND TECHNIQUE
Tricos are still showing at first light on the lower river, with caddis picking up from about 10:30am on and PMDs mixed in through the morning. Above Salida, hoppers, caddis, and attractor dries are drawing fish to the surface through the canyon water. A dry-dropper rig covers both stretches without re-rigging all day. Once the sun is off the water, swing a streamer through the deeper runs and undercut banks for the bigger fish that hold tight to structure during the heat.
FLIES FOR THIS WATER
Below Pueblo Dam, match what's actually showing at first light: small Trico patterns in the film early, then an RS2 style emerger subsurface as the spinner fall winds down, with red midge larvae as a searching pattern between hatches. We do not currently carry a dedicated Trico dry or RS2 as a standalone product. We can tie either to order, and our Technical Nymphing Leader is built for exactly this kind of light, precise presentation. Above Salida, an Amy's Ant or Parachute Adams still takes fish blind through the canyon's pocket water and riffles. Once the sun is off the water, our Woolly Bugger Bundle covers the evening streamer bite through the deeper runs and undercut banks.
RIG FOR PRESSURED WATER
​
A 3X to 4X tippet section for hoppers and large attractor nymphs off a longer leader keeps presentations drag free in the flatter tailwater runs below the dam, while a standard 4X to 6X taper still covers the pocket water and riffles above Salida. Check current water temperatures before you head to the river and plan around the cooler morning hours.

COMING SOON: LOW WATER TAILWATER BOX
​
We are building a limited-run box for exactly this kind of water: RS2s, Mercury Midges, Jig Frenchies, and a 3-Pack of our Technical Nymphing Leader, bundled for technical tailwater nymphing. It is still in development and not yet available in the shop. If you would like a custom order tied now, or want to be notified when the box is ready, reach out below.
