About this map

Avoca Island and its surrounding wetlands dominate this coastal reach of the St. Mary Parish and Terrebonne Parish line. This landscape is a complex network of bayous and islands at the mouth of the Lower Atchafalaya River, where human infrastructure like the Avoca Island Cutoff and Levee Rd meets the natural flow of the delta. Large interior water bodies such as Sweetbay Lake and Lake Gascha are separated by narrow landforms like Sword Point. The map documents the intricate hydrography of the region, tracing the paths of the Bayou Penchant, Bayou Shaffer, and Bayou Lawrence as they move through the marshy terrain towards the Gulf. This 2024 edition reflects the contemporary state of these vital Louisiana wetlands, capturing the current relationship between navigation channels and the shifting deltaic environment.
