Gulf Intracoastal Waterway West Closure Complex, Flood protection complex in Belle Chasse, Louisiana, US.
The Gulf Intracoastal Waterway West Closure Complex is a flood protection system in Belle Chasse that combines multiple water control structures. It features a navigable floodgate, a pumping station, reinforced floodwalls, sluice gates, and earthen levees designed to work together as an integrated network.
Construction began in August 2009 and the facility opened in April 2014 as part of New Orleans' expanded flood protection efforts. This project represented a major investment in the region's defense systems following earlier hurricane experiences.
The complex represents Louisiana's commitment to water management, incorporating engineering solutions that protect both urban areas and natural wetland environments.
The complex sits near where Harvey and Algiers canals meet, making it accessible from nearby roads. You can view the pumping stations and gates from several vantage points around the structures.
The facility removes over 25 miles of levees and floodwalls from direct storm surge impact, utilizing one of the largest interior drainage pump stations worldwide.
