In burned areas, what are the risks of mud and debris flows?

Increased rain runoff in burned areas can cause mud and debris flows. Multiple, federal, state, and local agencies are taking action to protect our watershed and prevent flooding, this includes:

  • In rural areas, the County is checking and installing debris-capture devices in culverts and ditches along rural roadways.
  • The Sonoma County Agricultural & Open Space District are assessing their properties within the burned areas for hazardous conditions including downed and damaged trees and areas where erosion may affect streams and watersheds.
  • Sonoma Water installed several rainfall and stream gauges in burned areas within watersheds affected by the 2017 wildfires and has since expanded the system to provide increased situational awareness for watershed protection. Sonoma Water has also installed new radar equipment to improve early warning forecasts for residents in high-risk areas. Visit sonoma.onerain.com for real-time data.
  • Sonoma Water has a Flood Forecast and Emergency Information website available to assist the public during storm events.
