A Living River: Supplementary Data for Downtown Tucson to Marana 2013 to 2020 water years


The Living River reports were developed to annually gauge conditions of this valuable ecosystem, the Santa Cruz River, and track the impacts of our community investment in wastewater treatment upgrades. This supplementary report summarizes data from water years 2013–2020. The report provides details on the water context and data for 16 indicators of river health.

The effort expanded in partnership with Pima County and the Regional Flood Control District in 2012 and the City of Tucson in 2020 to report on conditions in the flowing reaches in Pima County. The full report focusing on the 2020 water year for downtown Tucson to Marana is also available. Read the full report in Spanish.
