Seabrook Floodgate Complex is one of the major components of the Greater New Orleans Hurricane and Storm Damage Risk Reduction System built by the U.S. Army Corps of Engineers, New Orleans District. Finished in just two years, the $150-million plus project is located at the north end of the Inner Harbor Navigation Canal just south of Lake Pontchartrain and the Senator Ted Hickey Bridge. The structure works in tandem with the IHNC-Lake Borgne Surge Barrier to reduce the risk associated with a storm surge that has a one percent chance of occurring in any given year. Most recently, it helped prevent storm surge and flooding in New Orleans during Hurricane Isaac -- as the entire system worked as designed.
Ensuring commercial shipping continues unrestricted in southeast Louisiana, the U.S. Army Corps of Engineers contracts dredges to keep navigation “lanes” open. The challenge is in keeping the river’s navigable depth and width at authorized dimensions, a yearly focus for the corps. Recent operations on the Atchafalaya River saw the dredge Alaska working the Bar Channel. The authorized dimension for the navigation project is 20ft deep and a bottom width of 400ft.
The Bonnet Carré Spillway, part of the Mississippi River and Tributaries project (MR&T) is the southernmost floodway in the MR&T system. Located in St. Charles Parish, Louisiana, the spillway reduces risk for New Orleans and other downstream communities during major floods on the Mississippi River. This risk reduction is accomplished by diverting a portion of the floodwaters into Lake Pontchartrain and then into the Gulf of Mexico, bypassing New Orleans. This spillway was first opened during the flood of 1937, and nine times thereafter through 2011 to lower river stages at New Orleans.

Located approximately one half mile south of the confluence of the Harvey and Algiers canals on the Gulf Intracoastal Waterway, the approximately $1 billion project reduces the risk associated with storm surge for residences and businesses in three parishes on the west bank of the Mississippi River: Orleans, Jefferson and Plaquemines parishes.
