2024 Map of Grassy Lake

About this map

Upper Texas and Lower Texas anchor a landscape defined by the intricate waterways of the Atchafalaya Basin, where the border between Assumption and St. Martin Parishes meanders through cypress swamps and bayous. This map details the hydraulic complexity of the region, from the wide expanse of Lake Verret and Grassy Lake to the engineered precision of the William Canal and Himalaya Canal. Small settlements and family-named locales like Percle and Dwight Fields are concentrated along the northern and eastern road corridors, such as State Rte 400, while the southern reaches dissolve into a maze of wetlands including Bayou Sherman and Second Bay. The transition from established landings like Attakapas Landing to the dense network of interior bayous reveals the historic reliance on both water and overland travel in this part of southern Louisiana.
