East of Show Low and southwest of Alpine, the Black River is the longest fly fishing river in Arizona. Starting at 7,500 feet in deep pine forest, the river then flows through deep canyons filling nice pools ideal for wading. The Black River is known for its brown trout and rainbow trout.
In the upper reaches of the Black River, the most interesting sections are the East Fork of the Black River and the West Fork of the Black River within the White Mountains. The East Fork is very popular and can get crowded, so you may wish to fish in early Spring or late Fall. The West Fork is much less crowded and can be enjoyed all summer. Keep in mind that the West Fork, which has plenty of Apache Trout, is a catch-and-release zone. There are many pools and riffles on both that are ideal for wading.
Overall, Upper Black River is the 5th most popular fly fishing river of all 10 fly fishing spots in Arizona.
