About this map

Indianola and the coastal edges of Indianola Island occupy the southwest corner of this coastal survey, where the terrestrial landscape meets the expansive waters of the Texas Gulf Coast. This map documents a fragile shoreline defined by the meeting of Matagorda Bay and several smaller estuaries, including Keller Bay and Cox Bay. The geography of the early 21st century shows a low-lying marshy environment characterized by intricate waterways like Powderhorn Bayou and the sheltered basin of Powderhorn Lake.

The coastal morphology is further detailed by prominent features such as Mud Point, Rupert Point, and Sand Point, which delineate the reaches of the local bays. Settlement is concentrated along local routes like S Ocean Dr and Bell St, providing a look at the modern footprint of a region with deep roots in Texas maritime history. The survey also captures the northern extent of the area where Redfish Lake meets the larger bay system, highlighting the hydrological complexity of the Calhoun County coast.
