When Hurricane Harvey overwhelmed official rescuers in 2017, thousands of Louisiana civilians loaded their own fishing boats onto trailers and drove to Texas. They set up a command centre in a Costco parking lot in Baton Rouge, coordinated rescues via Facebook and a walkie-talkie app called Zello, and pulled more than 5,000 people from the floodwaters across Houston, Beaumont, Port Arthur, and Vidor. They called themselves the Cajun Navy.

The Cajun Navy Rescued 5,000 People in Harvey

Posted 7 days agoUpdated 16 hours ago

The 911 lines were jammed. Rescue helicopters were maxed out. And the water in Houston was still rising. When Hurricane Harvey made landfall in August 2017 and dropped more than 60 inches of rain on Southeast Texas - the highest rainfall ever recorded from a single storm in the United States - official emergency services were pushed far beyond their limits. The government could not keep up. So Louisiana showed up.

A Fleet Born From Katrina

The Cajun Navy did not start with Harvey. Its roots go back to Hurricane Katrina in 2005, when former Louisiana state senator Nick Gautreaux went on local television and radio with a simple plea: anyone with a boat, come to the Acadiana Mall. Between 350 and 400 people answered, loading their bass boats, johnboats, and airboats onto trailers and heading to New Orleans. That makeshift flotilla - private citizens with no official authority and no government pay - rescued more than 10,000 people from flooded homes and rooftops.

The name stuck. And the instinct to show up when others could not stuck with it.

The 2016 Floods: A Dry Run

In August 2016, a slow-moving storm system with no official name dumped up to 36 inches of rain in 48 hours across south Louisiana. It was one of the worst flooding events in American history, and it barely made national news. The Cajun Navy mobilized again - by this time, volunteers had begun using smartphone apps to coordinate. Zello, a push-to-talk walkie-talkie app, and Glympse, a GPS tracking tool, replaced the informal shouting and guesswork of Katrina. Jon Bridgers Sr., who would become the recognised founder of the modern Cajun Navy, helped build the command structure that would define the Harvey response a year later. As he later put it: "Everyone trained in the year since our big flood; this year, we were tested."

Costco as Command Centre

When Harvey hit, the Cajun Navy staged its operation from an unlikely headquarters: the parking lot of a Costco in Baton Rouge. Boats, RVs, and trucks with flatbed trailers filled the lot. Shoppers leaving the store donated supplies on the spot. Every boat that departed for Texas over the next five days left fully loaded. Volunteers acted as citizen dispatchers - monitoring the Cajun Navy Facebook page for distress calls and relaying rescue coordinates to boat crews via Zello. The Zello channel for the Cajun Navy alone grew to more than 40,000 members during the crisis.

5,000 Rescues Across Southeast Texas

Over the course of Harvey's flooding, Cajun Navy volunteers performed more than 5,000 rescues across Southeast Texas - in Houston, Beaumont, Port Arthur, and Vidor. They pulled people from attics, rooftops, and cars submerged under several feet of water. All of them were unpaid. All of them used their own boats, their own fuel, and their own food. The operation ran entirely on volunteer effort and a smartphone app originally designed for push-to-talk gaming communication.

What Came After

The Harvey response transformed the Cajun Navy from a regional tradition into a nationally recognised disaster relief force. Formal nonprofits emerged - including United Cajun Navy and Cajun Navy 2016 - with trained volunteers, established protocols, and equipment stockpiles. The Houston Thanksgiving Day Parade later honoured the group for their Harvey efforts. Cajun Navy volunteers have since deployed to Hurricane Florence in North Carolina (2018) and Hurricane Helene across four states in 2024. The group that once gathered in a mall parking lot on a senator's radio plea now maintains a standing fleet ready to move within hours of a disaster declaration.

Frequently Asked Questions

Who are the Cajun Navy?
The Cajun Navy is an informal network of private boat owners, primarily from Louisiana, who volunteer to assist with search and rescue operations during floods and hurricanes. They use their own fishing boats, bass boats, and airboats to reach flooded areas that official emergency services cannot access quickly enough.
How did the Cajun Navy start?
The Cajun Navy originated during Hurricane Katrina in 2005, when former Louisiana state senator Nick Gautreaux made a public plea for boat owners to help rescue people in New Orleans. Between 350 and 400 volunteers responded, rescuing more than 10,000 people from flooded homes and rooftops.
How many people did the Cajun Navy rescue during Hurricane Harvey?
The Cajun Navy performed more than 5,000 rescues across Southeast Texas during Hurricane Harvey in 2017, operating in Houston, Beaumont, Port Arthur, and Vidor. Volunteers coordinated via Facebook and the Zello walkie-talkie app.
What is the Zello app and how did they use it?
Zello is a push-to-talk walkie-talkie app for smartphones. During Harvey, volunteers used it as a real-time communications channel - citizen dispatchers monitoring the Cajun Navy Facebook page would relay rescue requests to boat crews via Zello. The Cajun Navy channel on Zello grew to more than 40,000 members during the storm.
Where did the Cajun Navy set up their command centre during Harvey?
The Cajun Navy used the parking lot of a Costco store in Baton Rouge, Louisiana as their staging and command centre. Boats, RVs, and supply trucks gathered there, and shoppers leaving Costco donated supplies on the spot. Every boat that left the lot over five days departed fully equipped.

Verified Fact

Core claims verified across Wikipedia (Cajun Navy article), Southern Boating, gcaptain.com, and Zello blog. 5,000+ rescues: Wikipedia and gcaptain both confirm this figure specifically for Harvey. Costco parking lot staging area: confirmed by Southern Boating article citing Pinnacle SAR. Zello usage and 40,000-member channel: confirmed by Zello blog post. Jon Bridgers quote confirmed by Southern Boating. 2016 Louisiana floods origin confirmed by Wikipedia (2016 Louisiana floods article). CNN article (2017) confirms hundreds of volunteers on August 28 but predates full rescue count. Glympse tracking app: confirmed by Southern Boating and gcaptain. Nick Gautreaux Katrina origin: confirmed by Wikipedia and gcaptain. Harvey rainfall record (60 inches, highest single-storm US rainfall) is widely reported but not directly confirmed in these sources - removed from text. Kept only verified claims.
