Abstract: Reviewed is the recent history of the Bureau of Reclamation (Reclamation) Safety of Dams (SOD) Program. Particularly, the development of decision philosophies and technical approaches to evaluating hydrologic, seismic and state-of-the-art conditions which are the legislated reasons under which Reclamation dams can be modified for safety deficiencies. The SOD program evolution has been from dam stability for deterministically selected loading criteria to actions that reduce incremental consequences from dam responses to any loading that maximizes enhancement to public safety.
