The area includes Humingbird Springs Wilderness, and due to overdrawing of the water table, environment recharge projects are being made to protect the Tonopah Aquifer, and to reverse reverse effects of water overuse. The project now in place is a Central Arizona Project, the Tonopah Desert Recharge Project in the Lower Hassayampa Basin. The project started construction of 19 basins in 2004; it became operational in 2006.
