A Living River: Charting Santa Cruz River Conditions Northwest Tucson to Marana (2018 Water Year)


This Living River report highlights results from northwest Tucson to Marana during the 2018 water year (October 1, 2017 to September 30, 2018). Comparisons are made to conditions in 2013, which is the baseline water year before the wastewater treatment upgrades. To explore more data, download the supplementary report. Living River reports were launched in 2008, when Sonoran Institute began tracking conditions of the stretch of Santa Cruz River in Santa Cruz County that flows year-round. This annual series was expanded in collaboration with Pima County and the Pima County Regional Flood Control District to include the flowing reach near Tucson in 2012.
