Flooding and standing water safety
Do not walk, run, cycle, skate, drive, or let children play through floodwater. Its depth, current, surface, contamination, electrical hazards, and hidden debris cannot be judged safely from appearance alone.
The direct answer
Check current official information first
Check active flood alerts, road or trail closures, evacuation instructions, and local emergency information before leaving and throughout a longer outing. Read the complete current alert for its affected area, timing, hazard, and protective action.

Why floodwater is dangerous
Floodwater creates drowning, injury, contamination, and electrical risks. Moving water can sweep away people and vehicles, while standing water can still be dangerous—especially for children.
CDC notes that floodwater can contain downed power lines, sewage, hazardous waste, germs, sharp debris, vehicles, and displaced animals. The safest general action is to stay out of the water.
Flood conditions can change over a short distance
Water can collect first in low roads, underpasses, drainage areas, stream crossings, and trail depressions. Rain may also fall upstream or outside your immediate view, changing water level or current where you are.
When to stop immediately
Adjustments only before you reach the water
A reasonable adjustment happens before exposure: choose a different activity area known to be open, move indoors, postpone the outing, or return another day after officials have reopened the area.
Guidance by outdoor activity
- Walking and running: turn around before entering flooded pavement, paths, fields, or low ground.
- Cycling and skating: dismount only to move away safely; do not ride through water that can hide holes, debris, or current.
- Dog walking: keep animals out of floodwater and away from drainage channels, contaminated water, debris, and displaced wildlife.
- Families: keep children away from water-covered roads, paths, drains, ditches, and cleanup areas.
- Driving to an activity: obey road closures and never drive into a flooded roadway.
What not to do
- Do not test the depth with a foot, bicycle, vehicle, stick, or pet.
- Do not assume still water is shallow, clean, or electrically safe.
- Do not cross a barricade or ignore a closure because other people have continued.
- Do not let children play in floodwater or with contaminated objects.
- Do not touch fallen power lines or water that may be in contact with them.
Exposure, injury, and escalation
If floodwater contacts skin, wash with soap and clean water as soon as possible. Clean and protect wounds, wash contaminated clothing separately, and seek medical attention when needed.
When activity may resume
Do not resume simply because rain has stopped or water looks lower. Return only after the alert and local instructions allow it, closures have been lifted, and the road, trail, or facility has been inspected and reopened by the responsible authority.
