Summary
Located in southeastern Arizona, this semiarid basin is drained by the San Pedro and Gila Rivers. The Lower San Pedro is a rural landscape with scattered towns and two extensive copper mining and processing operations. Groundwater from three aquifers (floodplain, unconfined basin-fill, and confined basin-fill or artesian) and fractured mountain hardrock is the principle source of water supply.
