About this map

Galveston Bay serves as the central focus of this mid-century hydrographic study, capturing the maritime infrastructure essential to the region's shipping economy. The Houston Ship Channel cuts a precise path through the bay, while the Intracoastal Waterway skirts the inner edge of the Bolivar Peninsula. At the tip of the peninsula, the settlement of Port Bolivar is documented alongside small coastal features like Horseshoe Lake and Oyster Lake.

The map details the complex sub-surface geography of the bay, from the broad Hanna Reef to the distinctive Halfmoon Shoal. Extensive engineering works are evident through numerous labeled Spoil Areas and the prominent Texas City Dike, reflecting a period of intense coastal management and dredging. A large Restricted Seaplane Area occupies the central waters, indicating the military and civil aviation requirements of the era.
