The SDCP recognizes the important links between groundwater, streamflow, and vegetation that still exist along some streams and springs in Pima County. Unfortunately, depletion of aquifers has altered streamflow and associated groundwater-dependent vegetation along the Santa Cruz River and other streams. The main purpose of this report is to establish priorities for potential expansion of Pima County's existing aquifer monitoring for groundwater-dependent ecosystems.
