2018 Map of Tigre Lagoon

About this map

Tigre Lagoon and the surrounding marshlands of south Louisiana are meticulously documented in this coastal survey, which captures the complex hydrography where the land meets the Gulf of Mexico. The landscape is defined by its transit networks, featuring the engineered stretch of the Intracoastal Waterway and the Acadiana Navigation Channel cutting through Vermilion Bay. These waterways are vital arteries for maritime commerce, intersecting with natural drainage systems like Bayou Petite Anse and Three Bayou. The map illustrates the boundary between Vermilion and Iberia Parishes, marking localized landmarks such as Champlain Point and the remote Shark Island. This topographic record provides a clear view of the Louisiana coastline's shifting interface of canals, natural bayous, and expansive tidal bays during the early twenty-first century.
