This two-page flyer is for the general public. Approximately 14,000 dams in the United States are classified as high-hazard potential, meaning that their failure could result in loss of life. The most important steps you can take to protect yourself from dam failure are to know your risk. Dams present risks, but they also provide many benefits.
This is a catalog of all the print publications that have been developed by FEMA for the National Dam Safety Program.
This brochure provides a summary of the information presented in FEMA P-484, Technical Manual: Conduits through Embankment Dams, including the effects of conduits on embankment dams, internal erosion and backward piping erosion, the factors that can lead to embankment dam failure, and best practices for conduits through embankment dams.
Whether for flood control, water supply, or recreation, dams play an important role in serving the community and managing a natural resource, but there are hazards and risks to consider when large volumes of water are stored. Sharing information about dams during a flood mapping study can help stakeholders obtain a more complete picture of the risks within a floodplain.
This brochure is designed to help the dam owner manage and reduce nuisance wildlife and wildlife damages at earthen dams. The brochure provides information on the types of nuisance wildlife damages, wildlife observation during routine inspections, wildlife identifcation, and basic damage repair.
The dam owner is the frst line of defense in the appropriate maintenance and safe operation of dams. This brochure describes the dangers presented by problem vegetation on earthen embankment dams and discusses how to identify problem vegetation. A quick quiz is included for dam owners to determine whether their dam may be at risk for problems related to inappropriate vegetation.
Increased awareness of dams and the risks they pose is an important part of dam risk management. Hazards from dams can be triggered by severe weather events, improper operation of the dam, or regular or emergency releases of water downstream.
Examples of the successful use of emerging technologies for the dam emergencies that occurred during Hurricane Matthew in 2016. This Fact Sheet also provides information on actions that can be taken to reduce risks, improve emergency response, and improve communication related to dams.
Examples of the successful use of notification methods for dam emergencies that occurred during Hurricane Matthew in 2016 to help stakeholders better understand notification methods that can be used during a dam-related incident. This Fact Sheet also provides information on coordinating notification messages.
Examples of pre-event exercises and training relating to dams and dam emergencies that were conducted prior to Hurricane Matthew in 2016 to help stakeholders better understand pre-event exercises and training efforts that will help them respond to potential dam emergencies.
