2020 Map of Bay L'Ours

About this map

The low-lying aquatic landscape of the Jefferson Parish and Lafourche Parish boundary comes into sharp focus through this late-era survey. The region is defined by a complex web of wetlands and waterways, where the waters of Bay L'Ours and Turtle Bay meet the coastal marsh. The map illustrates how human intervention has shaped these wetlands, most notably through the Harvey Cutoff, a significant navigational corridor that cuts through the natural hydrology of the bayous. These coastal reaches, including Bayou Perot and Bayou Rigolettes, reflect a landscape that is both ecologically sensitive and historically vital for water-borne transit in southern Louisiana. The grid systems of T17S R22E and T18S R22E underscore the formal land divisions that overlie this fluid environment of winding channels like Bayou de la Gauche.
