Reasons to Restore:
- Natural erosion
- Construction of navigation canals along the northeast shoreline of a Marsh Island.
- Deterioration of the north rim of Lake Sand and the interior marshes.
- Stabilizes the northeastern shoreline of Marsh Island.
- Stabilizing the northern shoreline of Lake Sand.
- Help restore the historic hydrology.
- Construction of 7 closures for oil and gas canals at the northeast end of Marsh Island.
- Protect the northeast shoreline with rock including the isolation of Lake Sand from Vermilion Bay.
This project is located in Iberia Parish, Louisiana, on the eastern portion of the Russell Sage Foundation Marsh Island State Wildlife Refuge and surrounding Lake Sand.
Project Effectiveness :
- Effective at reducing water level variability within the northern portion of the project area
- Water level variability did not increase in the project area as is did in R1 post-construction
- Reducing erosion rates at the northeast shoreline was partially met
- Reduced erosion in areas of applied rock dikes versus unprotected areas.
- The steel sheet pile, rock rip-rap wingwall, and stone bank paving installed at each end of closure No. 5 proved to be successful in preventing erosion during a storm event.
Previous Progress :
- The monitoring plan was finalized in January 2000 following with further data collection.
- Pre-construction and post-construction aerial photography were in the year 2000, and 2009 with future imagery analyses upcoming.
- Water level, submerged aquatic vegetation and shoreline position and movement data were also collected to evaluate project effectiveness.
Progress to Date :
- Construction was completed in December 2001.
- This is one of the three projects nearing the end of their 20 year lives.
- The Task Force will vote on the Technical Committee’s recommendation on the path forward for the following projects :
This project is on Priority Project List (PPL) 6.
