摘要：	Louisiana Gov. John Bel Edwards and members of the state's Coastal Protection and Restoration Authority (CPRA), along with state and federal leaders, broke ground August 10 on the Mid-Barataria Sediment Diversion, a $2.3 billion project located on the west bank of the Mississippi River near the town of Ironton in Plaque-mines Parish. According to CPRA, the project, over the course of 50 years, is expected to build or sustain up to 21 square miles of wetlands in the Barataria Basin, an area degrading due to subsidence, relative sea level rise and salt water intrusion. "Today will be remembered as a critical turning point for Louisiana's coast," Edwards said at the groundbreaking. "The Mid-Barataria Sediment Diversion will restore and rebuild thousands of acres of coastal land and provide better protection to our most vulnerable communities and critical infrastructure. I'm grateful to CPRA and our federal, state and local partners for their decades-long effort to make this first-of-its-kind project a reality." The project will include a gate structure on the river levee, a channel to funnel water and suspended sedi- ment westward toward Barataria Bay and an outfall structure at the opposite end. In low-water conditions, the structure will divert about 5,000 cubic feet per second (cfs.) of the Mississippi River's flow toward Barataria Bay. In high water, when the flow at Belle Chasse approached 1 million cfs., the flow through the diversion would top out at 75,000 cfs.
