Association of State Dam Safety Officials, Current Overview of Dam Safety in the U.S. (November 2007): “Roughly 85% of the US dams are regulated (not owned) by state governments. Most states are under-funded and under-staffed, and many do not have complete statutory authority to perform critical regulatory functions such as requiring Emergency Action Plans to warn and evacuate people in the event of a dam failure…Since 2000, more than 45 dam failures have been documented throughout the US.”
