When the call comes in for a water-related emergency—whether it’s a flash flood, a submerged vehicle, or a person swept away in a river—every second counts. But for first responders, every decision counts more. One wrong move in a swift water incident can result in tragedy—not only for the victim but for the responder, their crew, and the families they leave behind.
This is why swift water awareness is essential. It’s not just about rescue—it’s about survival. It’s about understanding the dynamics of water, recognizing the hazards, and knowing your limitations as a responder. Even if you never set foot in moving water, awareness-level training ensures you don’t become part of the problem when you’re trying to be the solution.
Let’s dive deeper into what swift water awareness means, why it’s critical, and how you can stay prepared for when the water rises.
What Is Swift Water?
“Swift water” refers to water moving at a noticeable current—specifically, any water traveling faster than 1.85 km/h (about 1.15 mph). That may sound slow, but make no mistake: swift water can become deadly in an instant.
Consider this:
Just 6 inches of moving water can knock a grown adult off their feet.
12 inches can sweep away a small car.
24 inches can carry away trucks and SUVs.
And it’s not just rivers and creeks. Flash floods, overflowing storm drains, even ditches after a heavy rain—any of these can create swift water conditions.
The Unique Dangers of Swift Water
Unlike static bodies of water like lakes or ponds, swift water carries a unique set of risks:
1.
Hydraulic Hazards
These include:
Strainers: Trees, fences, or other obstacles that let water through but trap solid objects (including people).
Low-head dams: Often called “drowning machines,” these structures create recirculating currents that can trap victims indefinitely.
Undercuts and sieves: Water flowing under rocks or between debris can pull people underwater.
These features are often hard to spot, especially in murky or debris-filled water.
2.
Entrapment
Moving water can force victims into storm drains, culverts, or vehicles—places with limited escape routes. Even shallow moving water can pin a person against a wall or object.
3.
Contaminants
Floodwaters are often full of hazardous materials—oil, fuel, sewage, sharp debris, and even dead animals. These pose not only trauma risks but also chemical and biological hazards.
4.
Cold Water Shock and Hypothermia
Even in warmer climates, water temperatures can be cold enough to induce gasping reflexes, muscle cramping, or unconsciousness—especially if the person is immersed unexpectedly.
5.
Deceptive Terrain
Water levels can rise rapidly, wash away bridges or roads, and erode embankments. What looks solid may be a trap.
The First Responder’s Role: Awareness-Level vs. Technician-Level
Not all first responders need to be certified swift water rescue technicians—but all should receive awareness-level training. This training doesn’t involve complex rope systems or in-water techniques. Instead, it’s focused on hazard recognition, scene safety, communication, and coordination with rescue teams.
Your goal at the awareness level is:
Recognize swift water hazards.
Prevent exposure to those hazards.
Support technical operations without becoming part of the problem.
It’s not about hesitation—it’s about informed action.
Scene Size-Up: Know What You’re Walking Into
Before jumping into a rescue mindset, the first step in any water-related call is a thorough scene size-up. This includes:
1. Personal Safety
Are you wearing proper PPE?
Is this scene within your scope and training?
Is your team accounted for?
2. Scene Hazards
How fast is the water moving?
How deep is it?
What’s the terrain like—are banks eroded or slippery?
Is there debris in the water?
Is weather a factor—are there upstream storms?
3. Victim Information
How many people are involved?
Are they visible or submerged?
Are they mobile or trapped?
Are they responsive?
4. Access and Egress
Can you get to them safely?
Is there a clear escape route?
What’s the best vantage point for communication and coordination?
Always assume the situation could deteriorate rapidly. Swift water incidents evolve fast—what’s safe now might not be in five minutes.
The “Reach, Throw, Row, Go” Rescue Model
This classic decision-making model should be burned into the mind of every responder at every level. It outlines the safest methods of rescue, from least to most risky:
1. Reach
If you can extend a tool—pole, ladder, rope, or branch—to the victim without entering the water, do that. Stay anchored, and maintain communication with your team.
2. Throw
Throw bags, flotation devices, or anything that can float and provide support. Remember to tie off throw ropes and throw past the victim so the current pulls the rope toward them.
3. Row
Only with trained personnel and appropriate equipment (inflatable rescue boats, dry suits, PFDs). Not typically part of awareness-level action but good to understand when supporting technical operations.
4. Go
Last resort. This means entering the water yourself. At the awareness level—you never go. Leave this to technicians with full PPE, backup, and a plan.
Personal Protective Equipment (PPE)
PPE in swift water situations is non-negotiable. Here’s what every responder should know:
Must-Have Gear:
Type V PFD: Designed for swift water. Built-in whistles and reflective tape are a bonus.
Water-specific Helmet: Protects from rocks, debris, and strainers.
Thermal Protection: Dry suits in cold water prevent hypothermia.
Water Shoes or Boots: Grippy, draining, and protective.
Gloves: Neoprene or water-resistant for grip and protection.
NEVER attempt a swift water rescue in turnout gear. It absorbs water, becomes heavy, and can kill you.
Communication and Coordination
Water rescues are often chaotic. Good communication can save lives—and poor communication can cost them.
Establish Incident Command: Even if it’s informal at first, assign roles.
Use Radio Discipline: Don’t clog the channel. Keep messages short and clear.
Assign Spotters and Lookouts: Someone needs to monitor conditions upstream.
Mark Entry/Exit Points: Use cones, flagging tape, or signage.
Use hand signals or whistles when radios fail or water noise overpowers audio communication.
Supporting Technical Teams
Even if you’re not performing the rescue, awareness-level responders play a critical role in:
Securing the perimeter to keep civilians and media out of harm’s way.
Transporting gear.
Providing lighting or power.
Handling victim medical needs post-rescue.
Helping decontaminate equipment and personnel.
Post-Rescue Protocols
After a water-related incident:
1. Decontamination
Floodwater and riverwater can be toxic. Rinse off gear and bodies as soon as possible. Change out of wet or contaminated clothing.
2. Medical Checks
Even if the victim appears fine, monitor for:
Shock
Hypothermia
Aspiration (water in the lungs)
Contamination or exposure symptoms
3. Mental Health Support
Water rescues—especially fatalities or near-misses—can be traumatic. Don’t ignore the emotional toll. Provide mental health debriefs and resources.
4. After Action Review (AAR)
Every incident is a learning opportunity. Break down what went well, what could improve, and how to implement changes in future responses.
Real-Life Incidents: Hard Lessons, Valuable Takeaways
The Bad: Arizona Firefighter Drowns in 2016
A firefighter entered floodwaters without a PFD or backup. The vehicle had already been abandoned. The current swept him under a culvert and he drowned before help could arrive. The incident sparked statewide training improvements.
The Good: Colorado Hikers Rescued in 2023
Five hikers trapped on a rock in rising floodwaters. The responding crew used a drone to assess the scene, throw bags for flotation, and coordinated airlift extraction. No one entered the water, and all survived.
The difference? Training. Awareness. Patience. Coordination.
Training Resources and Certification
Looking to boost your team’s awareness-level competency? Check these out:

The Final Word: Be the Responder Who Makes It Home
When you hear “swift water rescue,” your instinct may be to act fast. But as any seasoned responder will tell you, it’s not about acting quickly—it’s about acting correctly.
Swift water awareness means:
Knowing the risks.
Knowing your role.
Knowing your limits.
Every year, brave responders die trying to do the right thing the wrong way. Don’t be one of them.
Stay aware. Stay prepared. Stay alive.
