Background information on subsidence in Arizona, followed by a summary of the potential volumes of water to be withdrawn by Resolution Copper at the Desert Wellfield and current and historic water levels at the Desert Wellfield. Potential subsidence is estimated from the proposed water withdrawal based on observed subsidence in the Hawk Rock Area, which is located northwest of the Desert Wellfield.

This catalog has been prepared to summarize available information for selected springs and seeps in the Upper Queen Creek, Devils Canyon, Mineral Creek, and Dripping Springs Wash watersheds.
