Amidst the destruction wrought by Hurricane Katrina in 2005, a tradition of homegrown, all-volunteer boat rescue, unique to the low-lying Gulf States, resurfaced. At that time, Louisiana locals began to call themselves the Cajun Navy, constituting an informal, all-volunteer armada without affiliation to the much-maligned governmental response. After Katrina, the Cajun Navy would remain docked. But a decade later, the Navy sailed again.
The catastrophic flooding of the 2016 Great Flood elicited a new call to arms, reviving Cajun Navy Relief, one of the more formalized of the volunteer groups. The grassroots rescue effort provided much-needed back up to official first responders, who were inundated with emergency calls.
