A Living River - Charting the Health of the Upper Santa Cruz River
Though at times unnoticed, healthy rivers perform numerous services that benefit people. For example, vegetation growing along the river naturally slows flood flows, improves air quality, and provides shade, while soils in the floodplain filter and clean the water as it recharges groundwater supplies that support local residents.
The Upper Santa Cruz River supports a culturally and ecologically diverse region from its headwaters in the San Rafael Valley, Arizona, through Mexico, and back into the United States through Santa Cruz County, Arizona. How do we know if this important regional resource is a healthy living ecosystem?
Numerous groups research and monitor conditions along the Upper Santa Cruz River. The Living River report builds on these efforts by promoting a better understanding of the health of the river among watershed residents, land managers, and policymakers.
How does the report work?
The report annually tracks 10 indicators grouped in two main categories that represent important components of riparian and aquatic ecosystems (see below). Monitoring results are summarized for a given water year (October 1 – September 30) and evaluated against an appropriate standard set by federal and state regulatory agencies or the scientific community. Many of the standards are set by the Arizona Department of Environmental Quality (ADEQ).
A Living River focuses on a 20-mile stretch of the Upper Santa Cruz River between Rio Rico and Amado, Arizona. This portion of the river can be roughly divided into three reaches (stretches of river): Rio Rico, Tubac, and Amado.
Many organizations conduct ecological monitoring along the Santa Cruz River providing the important data for the Living River report series. Read more about who contributes data to the Living River series.
Learn about the development of the Living River report by reading the Technical Report (coming soon).
