Matagorda Island defines the narrow coastal threshold shown here, separating the Texas mainland's interior waters from the open expanse of the Gulf of Mexico. This 2010 survey focuses on the northwestern edge of the Gulf, capturing the barrier island's shape and the surrounding sea depths as they existed at the start of the decade. The map provides a clean cartographic record of the shoreline's interface with the sea, highlighting the essential maritime geography of Calhoun County before subsequent storm seasons or natural erosion could alter these delicate coastal boundaries.
