Whiskey Island Restoration in Full Swing
The restoration work on the Caillou Lake Headland barrier island, also known as Whiskey Island, is in full swing with approximately 20% of the project already completed.
The restoration of Whiskey Island is located along the south central coastline of Louisiana and is being constructed with funds from the settlement of the Deepwater Horizon oil spill.
The work includes beach and dune restoration using material dredged from the offshore ship shoal borrow source, as well as restoring the marsh platform along the western half of the island.
Utilizing a hydraulic cutter suction dredge and booster stations, Great Lakes Dredge and Dock Company will dredge approximately 10 million cubic yards of seabed sand and pump it 14 miles through a submerged slurry pipeline to create more than 900 acres of barrier island and marsh habitat.
GLDD recently released an aerial photo of the project site with the beach and dune template at the point of discharge over 1,000ft wide. At the time of the photo – taken on July 21, 2017 – the contractor has placed nearly 2,000,000 cubic yards.
