The National Weather Service and other local emergency services partners have created this resource to detail the higher probabilities of Flash Flood and Debris Flows across western and central Wyoming for those people affected by the 2012 Wildfires.

***While this page highlights the burn scar associated with the Fontenelle Wildfire, these impacts can occur down slope and/or downstream of any burn area, big or small.  Please contact local officials if you are unsure of your risk.***

Greatest Risk Area

  • All low lying areas, flood plains, current and historic channels
  • Anywhere that gravity will move water and debris
  • Note: Water and debris can be transported into areas that don't normally see water flow. All areas in and downslope of burned areas should be aware of the increased probability of Flash Flood and Debris Flows
  • Streams Impacted

  • South Piney Creek
  • Middle Piney Creek
  • North Piney Creek
  • La Barge Creek
  • Indian Creek
  • Springman Creek
  • Fish Creek
  • Spring Creek
  • Coal Creek
  • Darby Creek
  • Porcupine Creek
  • Beaver Creek
  • Variables Affecting Magnitude of Flash Flood/Debris Flow:

  • Steepness of terrain above your location
  • Intensity of burn
  • Intensity of rainfall
    • Half inch of rain in less than one hour can result in a
      Flash Flood
    • Any high intensity rain over a short period of time can result in a Flash Flood
    • Age of burn scar
    • Threat lessens over time; highest probability the first year after the fire
  • Most burn areas will be flash flood prone for at least 2 years

    What should people who live near burn areas do to protect themselves from potential Flash Flooding and Debris Flows?

    • Have an evacuation/escape route planned that is least likely to be impacted by Flash Flooding or Debris Flows

    • Stay informed before and during any potential event; knowing where to obtain National Weather Service (NWS) Outlooks, Watches and Warnings via the NWS, website, Facebook, Twitter, or NOAA Weather Radio
