From the benchWith flows at 388 CFS and exceptional clarity, the Arkansas is fishing as well as it has all year — rig a foam hopper or caddis dry with a Frenchie jig or PMD nymph dropper and work the mid-river seams from late morning through early afternoon when hatches overlap. As temperatures climb into the 80s this week, shift your focus to shaded canyon walls and deeper runs by 2pm, and don't put the streamer rod away — big browns are actively hunting in this warm, stable water. Evening caddis rises near Nathrop and Salida can be exceptional, so plan to stay on the water until last light.
