2010 Map of Keller Bay

About this map

Indianola and the surrounding coastline of Calhoun County are preserved in this 2010 study of the Texas coastal landscape. This specific survey area is defined by the complex convergence of Lavaca Bay and Keller Bay as they meet the broader expanse of Matagorda Bay and the Gulf of Mexico. The geography is characterized by distinct coastal features such as Mud Point, Rupert Point, and Sand Point, which delineate the intricate shoreline. Further south, the map details the terrain of Indianola Island and the marshy inlet of Powderhorn Lake. This 21st-century documentation by the U.S. Geological Survey emphasizes the evolving relationship between the land and the water in a region historically shaped by significant storms and shifting tides, providing a clear record of the shoreline's contemporary configuration.
