2019 Map of Mosquito Point

About this map

San Antonio Bay dominates this coastal landscape, where the shifting margins of the Texas shoreline meet the gulf. The Intracoastal Waterway cuts a straight course through the open water, serving as a vital artery for maritime traffic between the mainland and the barrier landforms. The map provides a detailed view of the complex island and reef structures that define this estuary, including Turnstake Island, Grass Island, and the avian-named Big Bird Island and Little Bird Island. Near the southern edge, the expansive Matagorda Island acts as a protective buffer against the open sea. This 2019 survey documents the modern configuration of tidal passes like Steamboat Pass and South Pass, while the northern mainland edge is marked by a few rural routes such as Falcon Point Rd and Lodge Rd near Mosquito Point.
