Dam and Levee Failure Evacuation Guide

Prepare for fast-moving flooding from a dam or levee failure by learning warning systems, evacuation routes, and high-ground options.
Understand the local risk
Dam and levee failures can produce rapid, destructive flooding with little warning. Determine whether your home, workplace, school, or regular travel routes are in an inundation or flood zone. Local emergency management, dam-safety offices, and evacuation maps are the best sources for location-specific information.
Know how warnings arrive
Enable Wireless Emergency Alerts and local notification systems, keep a battery-powered weather radio, and learn the meaning of local sirens. Do not wait for visual confirmation of rising water when officials issue an evacuation order.
Plan routes to high ground
Identify more than one route that moves away from waterways and toward higher ground. Practice without entering restricted areas. Include transportation, mobility equipment, pets, medications, and a meeting place. If you have no vehicle, register for local assistance when available and arrange a backup ride.
Act quickly
Evacuate immediately when instructed. If a flash flood is possible and water is rising, move to higher ground. Never drive, walk, or swim through floodwater; depth, current, contamination, and road damage may be hidden. Keep away from bridges over fast-moving water.
Return cautiously
Wait for official clearance. Avoid downed lines, unstable roads, contaminated water, and damaged buildings. Photograph damage safely and follow local drinking-water and cleanup notices. Review what worked and update routes and supplies.
