Subflow and the San Pedro River

The Santa Cruz River runs through Tucson, Arizona. At one time, there were abundant flows of water in the Santa Cruz, but now the riverbed is usually dry. After years of groundwater pumping in the Santa Cruz Valley, the perennial flows of the river stopped in the mid-20th century, vegetation along the banks of the river died, wildlife disappeared, and now, water only flows in response to precipitation events. My concern is that this may also be the fate of the San Pedro River, one valley over to the east.
