The H-Z Wash is a small but significant tributary of the Upper Salt River in central Arizona, located within the Tonto National Forest. This desert waterway flows through rugged terrain before joining the Salt River near the Diversion Dam Recreation Area, contributing to the larger Salt River watershed. While not a major paddling destination on its own, the H-Z Wash provides crucial access to the Upper Salt River, a popular stretch for flatwater paddling and fishing. The confluence area offers approximately 5 miles of gentle floating, with difficulty ranging from flatwater to occasional Class I rapids depending on water levels. This section is suitable for beginners and families, though all paddlers should be prepared for the challenges of a desert environment.

The best time to explore this area is typically from late winter through spring (March to May), when water levels are most reliable. A Tonto National Forest Upper Salt River boater permit is required during this peak season. Summer months can bring extreme heat and low water, while monsoon rains may cause flash flooding in late summer and early fall.

The landscape surrounding H-Z Wash is characterized by classic Sonoran Desert flora, including saguaro cacti, mesquite, and palo verde trees. Wildlife enthusiasts may spot desert bighorn sheep, coyotes, and various raptors soaring overhead. Key landmarks include the H-Z Wash access point itself, which serves as a put-in for Salt River trips, and the nearby Rafter Take-Out. The area provides stunning views of the Salt River Canyon and distant mountains, offering a quintessential Arizona backcountry experience.

Access to H-Z Wash is via the Diversion Dam Recreation Area, approximately 30 miles northeast of Globe, Arizona. This remote location requires careful planning and self-sufficiency for visitors. Historically, the Upper Salt River and its tributaries have been vital water sources for indigenous peoples and later settlers in this arid region. Today, the area plays a crucial role in water management for central Arizona, with Roosevelt Lake just downstream serving as a major reservoir.

Safety considerations include extreme heat, flash flood potential, and limited cell phone coverage. Paddlers should bring ample water, sun protection, and be aware of rapidly changing weather conditions. The area also offers opportunities for primitive camping, hiking (such as the nearby Vineyard Trail), and wildlife viewing, making it possible to create multi-day adventures combining paddling with other outdoor activities. For those seeking a unique desert paddling experience with easy access to both river and lake environments, the H-Z Wash and adjacent Upper Salt River provide a gateway to exploring the wild heart of Arizona's Tonto National Forest.
