The Arkansas River in Colorado meanders through some of the most breathtaking landscapes in the Rocky Mountains, offering anglers a paradise for fly fishing. Beginning its journey at the Continental Divide near Leadville, it stretches southeastward for approximately 150 miles, presenting a diverse array of fishing opportunities. Renowned among fly fishermen for its abundant trout population, the Arkansas River boasts some of the finest fishing waters in the country. From its headwaters to its lower reaches, anglers can target wild brown trout, rainbow trout, and cutthroat trout, among other species. The river's clear, cold waters, fed by snowmelt from the surrounding peaks, create ideal conditions for fly fishing year-round. Sections of the Arkansas River, such as the famed Gold Medal Waters near Salida and Buena Vista, consistently produce trophy-sized trout and provide anglers with exhilarating challenges. Whether casting dry flies, nymphs, or streamers, fly fishermen can test their skills against these wily fish while surrounded by stunning mountain scenery. Beyond the thrill of the catch, the Arkansas River offers anglers a unique opportunity to immerse themselves in the tranquility of nature. With its pristine waters, lush riparian vegetation, and abundant wildlife, it provides a serene escape for those seeking solace in the great outdoors. For fly fishing enthusiasts, the Arkansas River stands as a premier destination, beckoning with its beauty, bounty, and boundless opportunities for memorable angling adventures.

Flows here are around 240 cfs near Leadville as of Tuesday, and 540 cfs near Granite. This is a great time to hit the Upper Ark as some of our tailwaters are dealing with water temperatire issues during hot afternoons. 

Go with a 4X or 5X leader and rig on Dry-Droppers. For dries, go with patterns imitating hoppers, golden stones, yellow sallies, or green drakes. You'll also find solid caddis hatches in this stretch. Go with buggy patterns like a jigged CDC pheasant tail for a dropper.

In summer, the Arkansas River outside Leadville, experiences increased insect activity, making it an excellent time for fly fishing. Hopper-Dropper rigs are the go-to method for a successful day here.

Here are some effective fly patterns to consider during this season:

Terrestrials: Hoppers, ants, bettles and the like become key sources for food this time of year. Chubby Chernobyls, Stubby Chubbies, and Hippy Stompers make for good buoyant top flies in a dropper rig.

Caddisflies: As temperatures rise, caddis activity increases. Patterns like Elk Hair Caddis, X-Caddis, or Stimulators in sizes #14 to #18 can be effective imitations.

Stoneflies: Golden stone activity peak this time of year. Carry patterns like Pat's Rubber Legs, Hare's Ear Nymphs, or Prince Nymphs in sizes #10 to #14. For dries, a Chubby Chernobyl is hard to beat.

Streamers: As the water warms up, fish become more aggressive. Woolly Buggers, Sculpin patterns, and other streamers in various sizes and colors can attract larger fish.

Attractor Patterns: Bright and flashy attractor patterns like Perdigons or Rainbow Warriors can be effective in catching the attention of fish.

Remember to observe the water conditions and the behavior of the fish to determine the most effective patterns and  presentations. Also, be prepared to adjust your techniques throughout the day as conditions change.
