The south shoreline of White Lake has been retreating at an estimated average rate of 15 feet per year as a result of wind-induced wave energy. If the shoreline would have continued eroding in the project area, low marsh management levees likely would have been breached, which would have increased interior marsh loss rates in the project area.
This project included constructing segmented breakwaters to protect approximately 61,500 linear feet of shoreline to protect 687 acres of shoreline and interior marsh over twenty years. The breakwaters were constructed with gaps to allow aquatic organisms and water to move freely. An estimated 270,000 tons of stone was placed on geotextile fabric. Material dredged to create a flotation channel was placed beneficially behind the breakwaters to create approximately 172 acres of marsh substrate.
The project is located along the southern shoreline of White Lake from Will’s Point to the western shore of Bear Lake in Vermilion Parish, Louisiana.
Project construction was successfully completed in August 2006.
This project is on Priority Project List (PPL) 12.
