Program Mission: To maximize protection of human life & property against dam failure.

The Arizona Revised Statutes (A.R.S.) §45-1201 assigns the responsibility for supervision of the safety of dams to the Arizona Department of Water Resources.   Our objective is to maximize the protection of the public against loss of life and property by reducing the likelihood of catastrophic failure of dams within the Department’s jurisdiction.
