The remains of a home tumbles into the swollen Rillito River in October, 1983, in this photo by Tucson Citizen photographer Gary Gaynor. The floods of 1983 affected a large swath of Southern Arizona, from Tucson to Safford to Clifton to Nogales. According to the Pima County Flood Control District:

"The October 1983 flood was the largest flood of record in the Tucson area. In an unusual occurrence, between 6 ½ to 7 ½ inches of rain fell across the Tucson basin over a 5-day period. Flood and erosion damage was greatest along the Santa Cruz River, with extensive damage incurred on Rillito Creek, Tanque Verde Creek, and Pantano Wash. Damage to public infrastructure was estimated at $64 million, and four people died in flood related incidents."
