Underlying all the science relied upon by USPP members is the monitoring of various aspects of the hydrologic cycle. The monitoring is organized into four main hydrologic groups: groundwater in the Sierra Vista Subwatershed, the riparian system, the San Pedro River, and springs. Within these 4 groups, the USPP and members collectively fund and perform monitoring of 14 indicators of groundwater and surface water supply availability and quality. Since the USPP’s inception in 1998, the data has been stored in various member databases and reports, however, the new web-based hydrologic information portal (WHIP) is up and running to link users directly to the data and provide intuitive, spatial renderings of the data on maps.

The WHIP has three main functions:

  1. Provide readily accessible, geospatially accessed, hydrologic information through the synthesis of raw hydrologic data sets and include direct access to the raw data sets via direct web links.
  2. Provide data visualization tools that allow users to graphically view single data sets, side-by-side data-set comparisons, data overlays, and basic statistical analyses keyed to a map interface.
  3. Ensure the ready and timely availability of Sierra Vista Subwatershed and Upper San Pedro Basin monitoring data via a report-out template.

The monitoring results are reviewed by the USPP Technical Committee Science and Technical Advisors and reported back to the Partnership Advisory Committee (PAC). Recommendations for continued or additional monitoring funding are brought by the other committees or members to the Administrative Committee for budgeting and approval.
