1970 - The greatest natural disaster of record for Arizona occurred. Unprecedented rains caused rivers in central Arizona to rise five to ten feet per hour, sweeping cars and buildings as far as 30 to 40 miles downstream. Flooding claimed the lives of 23 persons, mainly campers, and caused millions of dollars damage. Water crested 36 feet above normal near Sunflower AZ. Workman's Creek was deluged with 11.40 inches of rain in 24 hours to establish a state record. Moisture from Pacific Tropical Storm Norma led to the severe flooding.
