ArkAnglers's Tip of the Week

Bighorn Sheep Canyon is in great shape and is fishing well for early December, offering a wider productive window on the water than the river further north. Temperatures are very mild this week which has prompted stronger feeding activity from trout. Slower, deeper runs and pools are the primary lies now for fish through the colder months. Midges (#18-22) are the primary forage with sporadic hatches prompting localized surface feeding from trout. We're also seeing fish feed opportunistically on golden stonefly nymphs and caddis larvae. Expect takes to be more subtle as water temperatures cool down, so pay attention to the minute movements of your indicator/sighter. Lots of water will be devoid of fish through the winter, so when you find a fish take note of the water type, depth, and speed to help locate other likely holding areas. Trout tend to congregate during the winter so where you find one you'll likely find several. 4x-5x tippet is appropriate for nymphing.

Description: About Arkansas River

The Arkansas River traverses about ninety miles between its headwaters above Leadville to the point where it rolls onto the prairie near Canon City. Over that distance, it flows through a high alpine meadow, drops through steep canyons of granite boulders and Ponderosa Pine, and courses through a high desert canyon. In each environment, populations of wild brown trout inhabit a river environment that teems with mayflies, stoneflies, caddis…small wonder that the Arkansas River was named Colorado’s most popular fishery in a recent Division of Wildlife survey. Along the banks of this river sit two remarkable mountain communities – Salida and Buena Vista. ArkAnglers has fly shops in both towns and our guide service spans the entire ninety miles of river, as well high mountain lakes on the Continental Divide, tributary streams, segments of the upper South Platte River, and some mid-elevation lakes known for their burgeoning trout populations. The range of altitude and climate in the upper Arkansas River valley allows us to guide year-round, the river providing a continuous supply of aquatic foodstuffs that keep fish active even in the winter.
