The National Dam Inspection Act came about due to a number of incidents that alerted the public and Congress to the need for improved dam safety measures. These incidents included:
*The poor performances of the Upper and Lower Van Norman (San Fernando) Dams during an earthquake which occurred near Los Angeles on February 9, 1971.
*The failure of the Buffalo Creek Tailings Dam in West Virginia on February 26, 1972.
*The failure of Canyon Lake Dam near Rapid City, South Dakota on June 9, 1972.
*In June 1972, severe flooding due to Hurricane Agnes endangered many dams. Some of these dams were overtopped and damaged.
