Dam Owner Resources

In the spirit of promoting teamwork between state regulators and dam owners, the Dam Safety Program would like to ensure that high-quality educational resources are available to everyone interested in dams. 

We are regularly updating this page. Check back for more information soon!


This Program hosts workshops for dam owners and technical training sessions for owners and engineers alike, but the Dam Safety Program also partners with other dam-safety focused associations, groups, and programs to make sure we can provide and share helpful knowledge for anyone who owns or lives near a dam.

Dam Owner Workshop

In November of 2018, the S.C. DHEC Dam Safety Program partnered with the Association of State Dam Safety Officials (ASDSO) to host and produce a Dam Owner’s Workshop specifically tailored to dams and owners located in South Carolina. The individual sections of this workshop were recorded and have been uploaded for easy viewing on the DHEC YouTube channel.

The recorded sections this Workshop covered are below. Each link will take you to a recording of the described section.

  1. An Introduction to Dams:
    1. The Functions of Dams
    2. Dam Types
    3. Dam Parts and Terminology
    4. Types of Spillways
  2. Dam Safety Laws and Regulations in South Carolina
  3. How Dam Failure Occurs
  4. Operation and Maintenance of Dams
  5. An Introduction to Emergency Action Plans
  6. Liability, Public Safety, and Security for Dams
  7. Dam Repair Projects: Engineers and Repair Options

'Dams & Inundations' App

The Dam Safety Program and DHEC G.I.S. (Geographic Information System) staff worked together to create an interactive map of all regulated dams and any inundation maps available for those dams. This publicly-available app is used by the Dam Safety Program to effectively locate regulated dams and by the S.C. Emergency Management Division to quickly find dams and assess what downstream impacts may need to be addressed in an emergency.

You can access the app by clicking the Dams & Inundations App.

Most of the inundation maps shown on the map are simulated by computer using a tool known as DSS-WISE Lite. For more information on how DSS-WISE Lite works, and to learn about the other models and methods the Program has used in the past, please check the “Methods Used to Generate Inundation Areas” document in the Downloads & Links section on this page.
You can use this tool to:

  • View all currently regulated dams in South Carolina.
  • Identify the name, location, and hazard class of any regulated dam.
  • Determine areas that may be at-risk if a dam were to fail.
  • Check the estimated depth of flooding in any at-risk area.

Association of State Dam Safety Officials (ASDSO)

The Association of State Dam Safety Officials is an organization that partners with state dam safety programs across the United States with the mission of “improving the condition and safety of dams through education, support of state programs, and fostering a unified dam safety community.” ASDSO provides a massive library of webpages, webinars, and other resources related to dam safety and dam ownership that are provided to the public free of charge. These resources can be found at the ASDSO website and navigating to the library of free information in the ASDSO Resource Center for Dam Owners.

You do NOT need to pay to access free information in ASDSO’s Resource Center, or at any of the resources we link below. While ASDSO may charge for access to certain webinars, classroom courses, or advanced engineering resources, the overwhelming majority of dam safety information is available to dam owners for free.

The S.C. Dam Safety Program generally finds the information from ASDSO to be in-line with our Program’s recommendations. However, because ASDSO is a national organization, some specific laws and regulations for dams in South Carolina may vary from what is documented on the ASDSO site and media.
