As an update to Lafourche Parish’s initial RESTORE Act Multiyear Plan which was accepted by Treasury on 2/18/2016, 

the following three projects were updated to include new proposed start and end dates of January 1, 2019 through 

January 31, 2021, for which an application has not yet been submitted to Treasury: West Belle Pass Marsh Creation, 

Catfish Lake Marsh Creation, and the Bayou L'Ourse to Leeville Marsh Creation projects. Additionally, the following 

project has been added in the amended multiyear plan:

Grand Bayou Freshwater Reintroduction Project ‐ Phase II and Phase III 

Description:

The Grand Bayou Freshwater Reintroduction Project consists of the following three planning phases: Phase I project 

was included in Lafourche Parish's initial multiyear plan and funded by Treasury at $79,870 for the creation of a 

preliminary engineering and design report that will identify project areas or components that are most feasible, and 

outline a recommended path forward for project implementation. Phase II is to create a modeling technical report that 

will describe the study methodology, assumptions, model development and results. Phase III is to complete 100% 

engineering and design package that will finalize construction plans and specifications and complete bid documents.

The primary goal of this underlying restoration project is to increase the flow of freshwater from the Atchafalaya River 

down Grand Bayou Canal via the Gulf Intracoastal Waterway (GIWW). The future construction phase is to increase the 

flow of freshwater from the GIWW into Grand Bayou Canal from approximately 600 cubic feet per second to 1,600 

cubic feet per second; redirect much of the freshwater from Grand Bayou Canal into the marshes east and west of

Grand Bayou Canal; create 112 acres of fresh marsh; and nourish an additional 14 acres of intermediate marsh west of

Grand Bayou Canal near Highway 24. The completion of Phase II and Phase III engineering, design, and permitting 

activities are required to advance the project toward implementation.

Need:

To complete Phase II and Phase III engineering and design, and permitting activities to advance the project toward 

implementation. Without restoration, this region will continue to see the breakup of marshes and the conversion of low 

salinity marshes to brackish and saline marsh. More than 16,000 acres of marsh have been lost in this area since 1949, and 

a significant amount of this land loss may be attributed to direct removal and altered hydrology from canal dredging.

Altered hydrology remains a current cause of land loss along with high rates of subsidence, which are estimated to be 

between 2.1 and 3.5 feet/ century (LCWCRTF 1999). Because of the high number of canals that have been dredged in the 

area, high salinity Gulf waters move rapidly northward into the marshes within the project area from Lake Felicity and Lake 

Raccourci. The amount of high salinity waters moving north is increasing as the marshes continue to breakup and 

disappear. The only freshwater input to this area originates from the GIWW along the northern project boundary. The 

freshwater inflow from the GIWW is restricted by the small cross‐section of the channel north of the Highway 24 Bridge 

that could be dredged and the cross‐section of the channel for several thousand feet south of that bridge. There is also a 

restriction (earthen plug) in Margaret’s Bayou, which prevents freshwater from moving east from Grand Bayou into the 

broken marshes. The wetland loss currently experienced in this area jeopardizes natural resources, ecosystems, fisheries, 

marine and wildlife habitats, beaches, and coastal wetlands and it makes nearby communities more susceptible to flooding 

from storm events. This project requires additional data collection and hydrologic analysis, as well as initial permitting to 

coordinate with agency and flood protection authority representatives.

Purpose:

The purpose of this project is to complete engineering, design, and permitting activities to advance the project toward 

implementation.

Objectives of Phase II and Phase III:

Phase II is to create a modeling technical report that describes the study methodology, assumptions, model development 

and results. The following activities will be undertaken during this Phase:

‐Conduct hydrologic modeling: This will include development of model scenarios needed for delineation of marsh areas of 

interest, hydraulic boundaries, and proposed dredging and spoil placement and to identify water control structures.

‐Review existing models, data, and recommend additional data collection to support modeling: This will include obtaining 

further relevant studies, models, topographic, and monitoring data, data gap analysis, and develop a data collection plan 

based on project needs and existing data.

‐Develop model geometry: This will update model geometry and topography and preform preliminary test simulations

‐Review existing monitoring data and develop boundary conditions for the model: This will include obtaining and 

reviewing data from applicable data sources.

‐Conduct calibration and verification of the system‐wide model: This will include performing calibration and verification 

simulations.

‐Perform model scenarios: This will establish base conditions and evaluate changes in the water level, velocity, and salinity 

in the study area and extract predicted values of these variables at several points of interest in the system

‐Prepare output charges, figures, and tables of water levels and salinity changes: This will provide time‐series charts, 

maps, animations, and tables reporting on the studied variables.

‐Create modeling technical report: The report will describe the study methodology, assumptions, model development and 

results.

Phase III is to complete 100% engineering and design package that will finalize construction plans and specifications and 

complete bid documents. The following activities will be undertaken during this Phase:

‐Prepare 30% design package: This will include estimated construction cost and duration, permit drawings and application 

submittal, and ongoing agency coordination.

‐Prepare 95% design package: This will include preliminary construction plans and specifications.
‐Complete 100% engineering and design package: This will finalize construction plans and specifications and complete bid 

documents.

Milestones:

1. Modeling Technical Report

2. 30% Design Package

3. 95% Design Package

4. 100% Engineering and design package

Location:

Phase II and Phase III planning activities will be conducted within the Gulf Coast Region of Lafourche Parish. The

underlying restoration project will also be completed within the Gulf Coast Region of Lafourche Parish.
