    Dam Safety Training

    Register on the Learning Center at


    Despite the criticism that Potential Failure Mode Analysis (PFMA) has received following the Oroville Dam spillway incident, it has been viewed as a standard of care for dam safety evaluations in the U.S., and with some possible improvements to be more expansive, is expected to be so into the future.  Many PFMA’s have been performed for state- and federally-regulated dams, and as a result of that investment, considerable knowledge has been obtained about vulnerabilities associated with specific dams.  As the federal dam owners have embraced risk assessment as the next step in ensuring that dam safety risks are properly evaluated and managed, it is expected that private and state dam owners will benefit from following suit.  Indeed, the Federal Energy Regulatory Commission (FERC) has recently adopted Risk Informed Decision Making (RIDM) as part of their engineering guidelines.  The intent of this training is to leverage and improve on the significant investment that has already been made in performing PFMA’s, and use this information to perform semi-quantitative risk assessments (SQRA) for individual dams or dam portfolios.  These assessments can then be used as a screening tool to identify PFM’s and overall risks which are not likely to meet Tolerable Risk Guidelines (TRG) based on life safety, and as a prioritization tool for reducing risk, performing additional investigations or studies, or performing quantitative risk assessments.  A simplified method for categorizing additional consequences such as those incurred at Oroville is also presented in this training.

    Eligible for 22 PDHs

    Target Audience

    The target audience for this training is dam owners and regulators who are familiar with the PFMA process, and are wanting to move these types of evaluations into the risk arena.  This would include FERC licensees and their consultants; private, municipal, and state dam owners; and state and federal dam safety regulators.

    Content and Commitment

    This course will take place over a week and  will cover review of the PFMA process, TRG’s, using the PFMA results to perform a SQRA (including additional required input and how to obtain it), estimating consequences including but not limited to life safety, assessing the results, building the dam safety case, and prioritizing risk reduction actions.  

    Registration and Cancellation Policy

    No registration is confirmed until full payment is received. Seating is limited and only those with paid status are guaranteed a workshop seat.  No refunds or credit if cancelled after 9/27/21
