2025 Map of Green Island

About this map

Green Island stands as a distinct landmark in the Laguna Madre, situated along the path of the Intracoastal Waterway. This coastal region, mapped by the U.S. Geological Survey, captures the shifting sands and low-lying topography of Padre Island to the east. The landscape is defined primarily by its maritime character, where small landforms like Deer Island punctuate the shallow waters. The map illustrates the specialized environment of the Texas coastline, where the navigation channel provides a critical artery for waterborne transit through a series of tidal flats and coastal wetlands. These features reflect the long-term interaction between natural barrier island formation and human engineering to maintain navigable passages along the Gulf coast.
