The Risk Prioritization Tool for Dams is a standards-based decision-making tool for risk-based dam safety prioritization to be used by state dam safety regulators throughout the country to identify those dams within a large inventory that most urgently need attention and then allocate resources accordingly. Once priorities are judged, risk acceptance or tolerability is a matter of policy that will vary from state to state (2008). (This download contains three files that need to be unzipped)

Emergency Operations Planning  Dam Incident Planning Guide.png

Emergency Operations Planning: Dam Incident Planning Guide
This Dam Incident Planning Guide supports state, local, tribal, and territorial emergency managers in planning for dam incidents and failures by summarizing the concepts that a community  should consider when creating dam incident-specific elements of local emergency operations plans. This guide builds on Comprehensive Preparedness Guide (CPG) 101: Developing and Maintaining Emergency Operations Plans.1 It also provides guidance for dam owners and operators on how to engage with emergency managers prior to an incident to ensure a well-coordinated response. Appendix A provides a general template for a community dam incident plan that can be adapted to meet each community’s needs (2019).

FEMA-SelectingConcrete-P1016.jpg

Selecting Analytic Tools for Concrete Dams to Address Key Events Along Potential Failure Mode Paths (FEMA P-1016)
The purpose of this document is to stress the importance of understanding the sequences of events leading to failure of concrete dams and selecting analysis methods that address these specific events. The selected analysis method may range from straightforward to complex, depending on the potential failure mode being analyzed. It is stressed that a less complex analysis with less uncertainty is the preferred strategy. Included in this report and the appendices are examples of this process. These examples are not intended to be a complete listing of concrete dam potential failure modes. Each dam is unique and has its own issues; therefore, it is important for the engineer to understand the potential failure modes and sequences of events that enable them (2014).

 

Microsoft Word - Summary of Existing Guidelines - Appendix E docx.png

Summary of Existing Guidelines for Hydrologic Safety of Dams (FEMA P-919)
The overriding purpose of this report is to document the available data and to present the state of the practice for evaluating the hydrologic safety of dams, including inventorying current practices used by state and federal agencies. This work included a review of hydrologic guidelines currently used in each state and federal agency that regulates dams, and was guided by an independent steering committee and reviewed by the Research Work Group. A subsequent publication will include new federal guidelines for the evaluation of the hydrologic safety of dams that could be applied nationwide (2012).

Emergency Action Planning for State Regulated HighHazard Potential Dams (FEMA 608)
Preventing loss of life from dam failure is the paramount concern of the National Dam Safety Program. This concern has intensified as a result of recent disasters that have focused attention on the state of the critical infrastructure in the United States and raised questions on the safety of dams nationwide. As part of a recent initiative to promote the implementation of Emergency Action Plans at all high-hazard potential dams across the United States, FEMA has asked all of the states to adopt the applicable recommendations contained in this paper (2007).
