2025 Map of New Harbor Islands

About this map

Chandeleur Islands stretch through the center of this maritime survey, illustrating the dynamic and shifting nature of Louisiana's outer barrier island chain. This remote section of Saint Bernard Parish is defined by fragmented landforms and the open waters of the Gulf of America. Key coastal features include the New Harbor Islands and the prominent Redfish Point, which help delineate the shallow navigation through Smack Channel. The map serves as a vital record of these low-lying landforms, which are subject to constant change from coastal processes. For those studying the geography of the Gulf Coast, this document provides the exact positioning of these disappearing landmasses and the channels that separate them before the turn of the decade.
