This page provides an overview on the topic of Dam Safety, as well as the National Dam Safety Program. It is intended to serve as a resource for people who live near dams, as well as agencies and local authorities with responsibility for dams and areas impacted by dams.
Raising Dam Safety Awareness
Dam Safety is a Shared Responsibility
Dams are a critical part of our nation’s infrastructure and all Americans enjoy the benefits they provide, including flood protection, water supply, hydropower, irrigation and recreation. However, our dams are aging and many are deteriorating, while downstream and upstream populations are increasing. Everyone has a role to play in creating a future where all dams are safer – including dam owners, engineers, community planners/leaders and federal and state regulators. For 30 years, the federal government has been working to protect Americans from dam failure through the National Dam Safety Program (NDSP). The program, which is led by FEMA, is a partnership of states, federal agencies and other stakeholders to encourage individual and community responsibility for dam safety. NDSP is an investment in preventing dam failures and reducing the impacts on lives and property that may be at risk from a dam failure. NDSP plays an important role in raising dam safety awareness and lessening the impacts if a dam was to fail. Key initiatives include:
- Assisting states in establishing and maintaining dam safety programs;
- Providing technical training to state and federal dam safety staff; and
- Supporting research and the development of guidance to advance the practice of dam safety to improve public safety.
Dam safety is a shared responsibility – you are encouraged to know your risk, know your role, know the benefits of dams and take action
National Dam Safety Awareness Day
Join FEMA and Support National Dam Safety Awareness Day on May 31st
FEMA encourages communities, states, and private sector dam owners across the nation to help promote dam safety and the benefits of dams either on May 31st (or during that time period). Here are some ideas that you can do to get involved and take action:
- Contact your local State Dam Safety Programs
- Organize an evacuation drill
- Work with the school system to set-up a field trip to a local dam
- Update your emergency action plan
- Start an outreach campaign to raise dam safety awareness
- Host a Dam Safety Awareness Day community event
- Post information on your website
Visit the National Dam Safety Awareness Day page for more information on how you can participate.
FEMA has prepared a 2-part video showcasing remarks made by Mr. David Miller and Mr. Doug Bellomo with FEMA and other state, local, and ASDSO officials at the 2014 Anniversary National Dam Safety Awareness Day event:

Dam Failure Information
There are more than 87,000 dams in the United States according to the 2013 update to the National Inventory of Dams. Approximately one-third of these pose a “high” or “significant” hazard to life and property if failure occurs.
Intense storms may produce a flood in a few hours or even minutes for upstream locations. Flash floods occur within 6 hours of the beginning of heavy rainfall and dam failure may occur within hours of the first signs of breaching. Other failures and breaches can take days and weeks to occur because of debris jams or the accumulation of melting snow.
