In the Event of a Dam Failure

Prepare for a possible flood

  • Use our inundation maps to determine if your residence is located in an area at risk for flooding.
  • Next, familiarize yourself with the area you live in and find the best evacuation route.
  • Understand the difference between a tornado/weather siren and Xcel Energy's dam failure siren. The dam failure siren emits a whoop tone followed by an audio voice message.

React to the warning siren accordingly

  • The audio voice message of the warning siren will indicate whether the siren is a test or actual warning.
  • If an actual siren warning occurs, seek high ground immediately.
  • Do not attempt to cross a flooded road. Seek an alternate route.

Where you should go

  • First choose the most efficient route out of the inundation zone.
  • Local emergency response agencies will use television and radio to announce the location of evacuation shelters.
  • For other questions visit our Dam Failure FAQ page.

Energy Saving Tip

Make sure to regularly change the air filters on your HVAC system (at least once per month). Old, clogged filters are far less efficient than new ones.


Break Ground, Not the Law

Always call 811 before digging in your yard to avoid hitting buried gas or electric lines. Not only is it the safe thing to do, but it's the law.
