Dam and Reservoir Safety Program Emergency Action Planning
The Dam and Reservoir Safety Program, with assistance from the department's Water Resources Center Surface Water Section is leading an effort to help develop Emergency Action Plans, or EAPs, for regulated dams in Missouri.
Completion of Emergency Action Plans can help save lives and reduce property damage during a dam safety emergency. Plans increase preparedness by organizing emergency contact information and evacuation procedures into an official document and by providing enhanced communications between dam owners and local emergency management officials.
Missouri dams 35 feet or more in height are regulated (10 CSR 22-1.020 (13)) and dam owners are required to complete a plan. The Dam and Reservoir Safety Program coordinates with dam owners, county Emergency Management Directors and other state and federal agencies to develop plans for all regulated dams.
Emergency Action Plans will contain the following information:
- Guidance for evaluating emergency situations occurring at a dam.
- Notification charts and emergency contact information.
- A list of residents, businesses and entities within the downstream inundation zone.
- A list of resources available for responding to a dam emergency.
- An inundation zone map (estimated boundary of the maximum water elevation resulting from a dam breach.
- Basic physical and geographical data for the regulated dam.
The Dam and Reservoir Safety Program assists the owners in completion of the plan by providing an inundation map and helps complete portions of the template. County emergency management directors may provide critical emergency contact information and assistance in identifying structures located within the downstream inundation area.
When to start making your Emergency Action Plan
You can start developing your Emergency Action Plan now. The department has a sample template available on the Web. You can use it to get started. After the department completes inundation maps and partially filled-in templates for each dam in the state, you can use the information to complete your personal plan. Inundation maps and partially filled-in templates are being developed on a county by county basis. Counties have been prioritized based upon population and the number of regulated dams within regions of the state. Those maps and partially filled-in templates will be among the first available.
Examples of Inundation Maps (to be provided by department's Water Resources Center)
Emergency Action Plan Development Process
- The Dam and Reservoir Safety Program begins work on the Emergency Action Plan template specific for your dam. This includes developing an inundation map and filling in technical, physical and geographical data for your dam.
- Your local emergency management director or staff may be able to supply part or all of the information needed to complete the notification sheets, emergency contact information and assistance in identifying structures located within the downstream inundation area.
- 2a. If local Emergency Management Directors are able to provide that information: The department will send the template to the Emergency Management Director, then the template with that information will be sent to the owner for final review and completion.
- 2b. If local Emergency Management Directors are not able to provide information: The department will send the template directly to the dam owner to complete that information.
- For an Emergency Action Plan to be completed, the owner is required to fill out the incomplete portions of the Emergency Action Plan template. On completion, a copy of the final plan for your dam should be provided to the Water Resources Center Dam and Reservoir Safety Program and appropriate county and local emergency responders.
