What is Our Goal?

4

Sample photo box





• To educate Emergency Managers on what dams are within their jurisdictions, their locations and their hazard ratings

• We want to help educate the involved parties as to what their roles and responsibilities are in the event of a dam emergency

• We want to build connections between Dam Owners, Dam Operators, Emergency Managers, and our office.

• We want to help improve the overall execution of Dam EAPs

Recent Dam Failures in Nevada

• Washoe Lake Dam (just saved from failure)

• Echo Canyon (Spillway)

Hazards• A dam’s hazard rating refers to consequences of a dam's failure, not the

condition of the dam• A dam is considered high hazard if a failure or mis-operation is expected to

result in loss of life• A dam is considered significant hazard if a failure or mis-operation is

expected to result in significant economic damage or loss of a lifeline• Hazard classification can change due to downstream development

Aging Infrastructure• The average age of the more than 90,000 dams in the United States is 56

years old • By 2025, 7 out of 10 dams in the United States will be over 50 years old• Over half of the dams in the United States are owned by a private entity• Dams can fail on first filling and can fail at 100+ years old

Vital ASDSO Statistics and Facts

Emergency Action Plan IN EFFECT

11

• Imagine YOU are the Emergency Manager/Incident Commander receiving this phone call.

• What information should you gather from the phone call?

Sample photo box





What Do You Do?

13

• Discussion Time

*As a Sheriff, Fire Chief or Emergency Manager, did you know that most of the time you are one of the first contacts listed and often named as the Incident Commander in many up to date Dam EAPs?

Emergency Managers, you are always listed as a plan holder in up to date EAPs

Sample photo box





What Information Would be Helpful to Have Prior to the Call?

14

• The name of the dam

• Location of the dam

• Dam owner(s) contact information

• General facts about the dam; hazard classification, size and capacity.

• If this dam is a high or significant hazard you should have an EAP on file and be listed as both a contact and a plan holder in that EAP.

• The EAP should include an inundation map.

• Aside from the inundation map you should have an evacuation plan specific to that dam already created that you can immediately reference.





How Do You Get This Information?

16

• DAM OWNER: It is the Dam Owner’s responsibility to provide this information to all responsible parties listed within an EAP

• You should request this information so that you have all of the tools and information you need in the event of a dam emergency in your area.

The dams within State of Nevada Jurisdiction:

• For High Hazard dams there are 144 EAPs complete of 144, but not all are up to date.

• For Significant Hazard dams there are 72 EAPs complete of 82.

• Low Hazard dams are not requiredto have an EAP. It still important to know where they are located.

What is Our Role in Dam EAPs?

20

Sample photo box





• We ask that dam owner(s) have an EAP and Inundation Map created and keep the plan and maps up to date.

• We review their EAPs based on the FEMA P-64 Federal Guidelines for Dam Safety

• We remind them every 5 yearsto update their EAPs

• We ask the owner to send their EAP to theirCounty/City Emergency Managers, NWS, NDEM

• We ask to be notified when an EAP is implemented

How Can We Help You?

26

Sample photo box





• What can we ask of Dam Owners or require within EAPs that would better serve you as Emergency Managers/Incident Commanders?

• How can the State Engineer’s office help you with regards to dam safety?

Next Steps

27

Sample photo box





• Our office is working with State DEM and National Weather Service to get all EAPs in electronic format.

• Emergency Manager’s should gather and review EAPs to determine roles and provide comments to owner if there are changes needed.

• Conduct and participate in ‘table top’ dam failure exercises.

• If you have questions, comments or concerns, please contact our office.
