2025 Map of Bay Ronquille

About this map

Grand Terre Islands and the complex salt marshes of Plaquemines Parish characterize this 2025 coastal topography. The landscape is a network of interconnected water bodies such as Lake Grand Ecaille, Bay Ronquille, and Bay Cheniere Ronquille, where the distinction between land and sea is constantly evolving. In the eastern portion of the sheet, the Robinson Canal provides a structured waterway through Bayou La Mer, while prominent landmarks like Point Cheniere Ronquille serve as nautical and geographic markers. The presence of the Gulf of America to the south underscores the area's exposure to the open sea. This mapping reflects the modern shoreline and maritime passages, including Quatre Bayou Pass and Bay Dispute, which are critical for navigating this fragile deltaic environment. Local historians and researchers can observe the current state of these marshlands, which have been shaped by both natural processes and man-made interventions like the canal system.
