Whiskey Island Caillou Lake Headlands restoration area 2016–2019 shorelines, Louisiana Barrier Island Comprehensive Monitoring Program

Metadata Updated: July 6, 2024

This data package includes a high-water shoreline position map and a structures map for each year from 2016–2019 for the Natural Resource Damage Assessment (NRDA) Caillou Lake Headlands project area (TE-0100), also known as Whiskey Island. The project created 170 acres of marsh habitat and 917 acres of dune and beach habitat on Whiskey Island in Terrebonne Parish using material dredged from Ship Shoal. For more information on this restoration project, see the project page on Louisiana Coastal Protection and Restoration Authority’s (CPRA) Coastal Information Management System (
Together with previous shoreline products developed for CPRA's Barrier Island Comprehensive Monitoring (BICM) Program Phase 2, this suite of Whiskey Island shoreline position maps spans the time period before, during, and after the restoration project was conducted. The shorelines were delineated primarily using linework from existing habitat classifications of Whiskey Island. Please see the Processing Steps sections of the individual metadata files for information on methodology for map development. The BICM Program, for which these maps were developed, uses both historical data and contemporary data collections to assess and monitor changes to barrier islands, and develops data products, including shoreline position maps. For more information about the BICM Program, see Kindinger and others (2013).
