2024 Map of Cat Island Pass

About this map

Timbalier Island stretches across the eastern reach of this coastal survey, serving as a narrow barrier between the open waters of the Gulf of Mexico and the interior expanse of Terrebonne Bay. The map documents a highly dynamic maritime landscape defined by shifting sands and the deep-water channel of Cat Island Pass. To the west, the isolated remnant of Wine Island stands as a point of reference for researchers tracking the ongoing transformation of the Louisiana shoreline. This document provides a precise record of the parish’s southernmost reach, where the delta meets the sea and where traditional barrier landforms continue to evolve against the elements.
