Santa Cruz River Initiative 

SCR LandingPageCollage

The Santa Cruz River has drawn people to its life-giving waters for over 12,000 years. Rain coursing down mountainsides replenishes the river as it flows over 200 miles through desert communities in southeastern Arizona, northwestern Mexico, and the Tohono O’odham Nation. 

Modern society has stressed this water system, and much of the Santa Cruz River is dry.  A few of the sections of the Santa Cruz with year-round water depend primarily on treated wastewater, or effl uent, released into the riverbed. This practice supports wetland habitats that are not only becoming increasingly rare but are some of last living examples of the river heritage that long supported people in the region.

thumb_SCRInitiativeThe Santa Cruz River Initiative is focused on restoration of watershed health with an aim to improve local water supplies. Our overall goals are to: secure river fl ows, improve water quality, protect and raise groundwater levels, reduce water runoff by enhancing infitration, and bring the successful model to other communities.
