Poydras was first settled in the 18th century by Isleños when Louisiana was a Spanish colony. Presumably, the town is named for Julien Poydras. Albert Estopinal, Jr., a St. Bernard Parish district attorney, judge, and sheriff, was born in Poydras in 1869 to later U.S. Representative, Albert Estopinal, Sr. The locally constructed levee failed during the 1922 flood and the community of Poydras was destroyed. Some historians claim that the levee break was intentional to save the City of New Orleans. The New Orleans river stage dropped.2 foot within 24 hours of the Poydras crevasse and a sound levee had been inspected and reported only 30 minutes before the breach occurred. Poydras was severely damaged by the impact of Hurricane Katrina on 29 August 2005.
