Dam Safety Evaluation for a Series af Utah Power and Light Hydropower Dams, Including Risk Assessment: The Owner Perspective

Utah Power and Light Company (UP&L) owns a series of six dams on the Bear River in Utah and Idaho. These dams are regulated by the Federal Energy Regulatory Commission (FERC). Not all the dams currently meet the FERC’S standards for flood and earthquake loading. Their internal conditions, however, have been found to meet all important FERC criteria. A dam safety evaluation study was performed to explore the suitability of site specific standards for the UP&L dams and to propose and evaluate alternative remedial actions. The investigation was performed to provide UP&L management with information for use as a basis for their proposals to the FERC for remedial actions at their Bear River dams.
