About this map

Port Arthur and its surrounding industrial marshlands are defined by an intricate network of man-made waterways and protective infrastructure. The city center is shielded by the S Levee, separating the urban grid from the expansive Sabine Lake. This 2019 survey highlights the massive engineering required for the local oil and shipping economy, including the Sabine Neches Canal and the Intracoastal Waterway, which carve through the landscape to create deep-water access for locations like Texaco Island.

South of the city, the landscape dissolves into a complex system of bayous and lakes, such as Johnson Lake and Mud Lake, punctuated by landmarks like Blue Buck Point and Mesquite Point. This map captures the coastal border between Texas and Louisiana, where the Sabine Pass serves as the critical gateway to the Gulf. The presence of the Taylor Bayou Outfall Canal and various basins reflects the ongoing management of this low-lying coastal environment.
