Southwest: Desert Oasis Fly Fishing

In the arid vastness of the American Southwest, cold water is currency and the rivers that carry it hold world-class fly fishing. From the legendary tailwaters below desert dams to alkaline stillwaters teeming with massive trout, the Southwest defies every expectation.

The Winter Guide: Cold Water, Warm Hands, Willing Fish
