2018 Map of Grassy Lake

About this map

Attakapas Landing serves as a primary access point to the intricate wetland systems of Assumption and St. Martin Parishes in this 2018 survey. The landscape is defined by the vast waters of Lake Verret and Grassy Lake, connected by a network of natural bayous and man-made passages such as the William Canal and Himalaya Canal. Small settlements like Upper Texas, Lower Texas, and Bayou Crab are concentrated along the northern and eastern fringes where higher ground or levees permit development. The southern portion of the map is dominated by dense marshland and winding waterways including Bayou Felix and Bayou Sherman, illustrating the persistent swamp character of the Atchafalaya Basin region. This map provides a detailed view of the modern drainage and navigation infrastructure, featuring numerous named passes like Persimmon Pass and Simon Pass near Lake Palourde.
