Project Location

The project is bounded on the north by the Gulf Intracoastal Waterway (GIWW), the east by a north/south line from Lake DeCade to the GIWW, the south by Lake Mechant and Lost Lake, and to the west by a north/south line from Lost Lake to Avoca Island in Terrebonne Parish, Louisiana.

Project Description

The objective of the project was to divert freshwater flow within the Penchant Basin in Terrebonne Parish from northwestern to southeastern sub-project areas coupled with protection measures to reduce inundation of fragile marsh areas in overall Penchant Basin in Terrebonne Parish.

Issue Addressed

Area problems include major hydrologic alterations, interior marsh erosion, subsidence, saltwater intrusion, herbivory, and hurricane damage.

Project Goals

This project will combine the long-term realignment of Penchant Basin hydrology with restoration and protection measures aimed at maintaining the physical integrity of the area during the transition toward greater riverine influence.
