2019 Map of La Coste

About this map

The Medina River carves a winding path through this corner of South Texas, defining the landscape between the historic community of Castroville and the town of Lacoste. The map highlights a complex water management system essential to the local agriculture, including the Medina Irrigation Canal and the Natalia Canal, which support the surrounding ranchlands and fields. Significant landmarks such as the Castroville Municipal Airport and Rhins Hill stand as prominent features in an area otherwise characterized by creek systems like Little Sous Cr and Polecat Cr. Near the southern border, the N Prong Atascosa River begins its course, while several small lakes, including Ruby Lake and the Alamo Angus Ranch Lake, provide critical local water resources. This survey illustrates the continued development of the corridor along FM 471, connecting the established settlements of Pearson with the growing rural infrastructure at the Bexar and Medina County line.
