Best Bets on Equipment

You can fish multiple sets of roads, reels, and flies with success on the Arkansas, but an ideal rig is a 9 foot 5 to 6 weight rod with a floating line. 9-foot leader is a great base for great bites. For flies you can use dry flies, nymphs, and streamers, depending on the hatch. The Arkansas has many distinct hatches and you can easily find success by matching the hatch. Unlike other spots in Colorado fish on the Arkansas hit a wide variety of flies so bring plenty of tackle to find the biggest fish. You can fish from the shore, wade, or float the Arkansas River so match the waders to your fishing. Chest waders are recommended if you know you’ll be wading into deeper spots.
