Arivaca Creek

To provide comments on this watershed for consideration in the Floodplain Management Plan, contact Greg Saxe

The Arivaca Creek watershed is a tributary to Altar Wash originating near the historic community of Ruby and passing through the Village of Arivaca. Its confluence with Altar Wash is near west Arivaca-Sasabe Road. Within Pima County, it is comprised of 70,982 acres. This watershed is generally sparsely populated, but its waters can rise quickly and become a significant hazard. There are numerous at-grade road crossings on Arivaca Road and elsewhere that could pose a serious threat to life when water is flowing in the many tributaries. With few alternate routes around flooded roadways, wait for floodwaters to recede before driving through these areas. Flows will gener-ally recede fairly quickly. This watershed contains 3,231 acres of SFHA and 10,872 acres of Pima County Regulated Riparian Habitat.
