The Gila River is a significant waterway that flows from the mountains of southwestern New Mexico into Arizona, spanning approximately 649 miles before joining the Colorado River. It represents one of the longest rivers in the American Southwest and offers diverse fishing opportunities across its varied habitats. The river's headwaters begin in the pristine Mogollon Mountains within the Gila Wilderness of New Mexico, before winding through desert canyons, forested areas, and eventually into more arid landscapes. The river and its tributaries support a remarkable ecosystem with both native and non-native fish species, making it a destination for anglers seeking both traditional sport fishing and unique native species experiences.
