(520) 724-4633.
The San Pedro River originates in Mexico and flows through Co-chise County prior to entering Pima County. Near Pima County, it drains the eastern slopes of the Rincon and Santa Catalina mountains and western slopes of the Galiuro Mountains. The San Pedro exits Pima County into Pinal County south of the community of San Manuel. Though it is one of the largest watercourses in Pima County, the remote and rural nature of this area means that few people are impacted by flooding on the San Pedro River and its tributaries. Within Pima County, this watershed is comprised of 181,901 acres and contains 3,231 acres of SFHA, 1,674 acres of locally identified floodplain and 15,438 acres of Pima County Regulated Riparian Habitat.
